Currently(10.30am) 8/8 cloud continous mod to heavy rain. In the last 48 hours 40mm here in Kilsyth. Yesterday we experienced gale force winds all day in this area. We were blacked out 5 times including once this morning. Driving along Mt Dandenong road yesterday was quite hazardos as there was a lot of debris on the road ranging from twigs and small leaves and branches up to large branches and large uprooted trees. Quite a few houses in the area have suffered damage from having trees and large branches fall onto their property Winds have now eased. Yesterday the wind was from the SE which only blows strongly one or twice a year from this direction in Melbourne. When it does though the outer eastern suburbs around the foothills of the Dandenongs (ie Ferntree Gully, Boronia Kilsyth, Montose etc) get a funnelling or wind tunnel effect which greatly increases the wind in these foothill suburbs. The wind here in Kilsyth which was the worst affected suburb would have been gusting well over 40 knots for much of yesterday. I drove from Kilsyth to Ringwood about 10km to the west of here at 5.00pm yesterday. When i left here the wind was really blowing and as I mentioned there was a lot of debris on the road. In Ringwood though the wind was much lighter no more than 15-20 knots and there was no sign of any wind damage. When I returned home a couple of hours later the wind here was as strong as ever and the area was blacked out. I havent read any reports on this wind funnelling affect It must occur in many areas of Australia (that are near Mountains) under certain wind conditions.

By the way, do you know what > Wycheproof's highest daily rainfall record is? > > Yours, > Kevin Phyland. 111.8mm (and it's in November, so you can't even claim a November record). Swan Hill's record was actually rather low by the standards of the region - most of northern Victoria has 24-hour rainfall records in the 80-110mm range, occasionally higher (e.g. Beulah 165.6) where a place has presumably ended up underneath a particularly soggy thunderstorm. A few daily rainfall records for Victoria (first figure is for any month, second for November). * indicates the record was broken this week (this may be incomplete): Mildura 91.2/65.5 Birchip 88.6/51.3 Ouyen 83.8/49.0* Donald 93.5/77.2 Nhill 133.2/50.0 Wycheproof 111.8/111.8 Warracknabeal 77.0/31.6 (I think this is a short record) Stawell 91.7/65.5 Echuca 90.7/77.0 Kerang 127.0/54.1* Bendigo 87.6/63.5 Swan Hill 68.8*/51.1* Wangaratta 129.3/64.8 Castlemaine 91.2/50.6 Ballarat 121.9/71.2 According to the Barwon River flood warning there have been falls exceeding 200mm in the upper catchment, although the highest at a Bureau daily reporting station in that region is 72 at Meredith. Also a bit of interest last night in Melbourne - quite a bit of wind damage, particularly in the suburbs at the base of the Dandenongs - I suspect this may have been a Melbourne variation of the 'gully winds' that sometimes affect the eastern suburbs of Adelaide in easterly airstreams. Any comments from those who live out that way? Nothing particularly exceptional that I saw, either in the city or at home (Heidelberg).

Reply-Receipt: pgraham1 at extro.ucc.su.oz.au Reply-Read: pgraham1 at mail.usyd.edu.au Sender: aussie-weather-approval at world.std.com Reply-To: aussie-weather at world.std.com Hi everyone In response to Jimmy's letter about mail to this list, I have been thinking that it might be a good idea at some stage to set up a separate mailing list specifically for significant weather events here in Australia (eg. The Brisbane storm on 13th of October). That way, only messages about significant weather would be posted while all Australian weather related data could still be sent to this list. A possible policy for such a list could be: no personal replies, no real time observations or predictions and all messages to be only information related to significant weather (eg, Floods, Severe Storms, Record Temperatures etc...). The reason I have been thinking of this is because the volume of mail sent to this list might discourage people from continuing to subscribe to it. We have already lost some people who, in the past, have provided valuable information. I have a feeling it is for this very reason: too many messages to sort through, some of which are not weather related at all, and not much time in which to do so. One last observation: perhas we could compile a "frequently asked questions" document, since on a few occasions I have noticed the same questions being asked when they have been answered some time before. What do peole think about these ideas? - Paul G. ---------------------------- Paul Graham m3052695 at hardy.ocs.mq.edu.au ---------------------------- -------------------------------------------------------------------------------------- From: Paul_Mossman at agd.nsw.gov.au X-Lotus-Fromdomain: NSW_AG To: aussie-weather at world.std.com Date: Fri, 13 Nov 1998 11:30:00 +1000 Subject: aussie-weather: TS Prospect today Sender: aussie-weather-approval at world.std.com Reply-To: aussie-weather at world.std.com Howdy all.

Some observations: significant low level moisture and heating beginning to occur, mid-level dry air and upper level jet with a local maximum over northern NSW. Haven' t had a chance to examin the latest wind data but with the low situated over southern NSW, I think we have a good chance for some significant storms. - Paul G. ---------------------------- Paul Graham m3052695 at hardy.ocs.mq.edu.au ---------------------------- -------------------------------------------------------------------------------------- X-Sender: bayns at nornet.nor.com.au X-Mailer: Windows Eudora Light Version 3.0.1 (32) Date: Fri, 13 Nov 1998 11:01:47 +1000 To: aussie-weather at world.std.com From: steve baynham Subject: aussie-weather: goldcoast weather Sender: aussie-weather-approval at world.std.com Reply-To: aussie-weather at world.std.com hey, looks very stormy here today! temp. 22 C although thats probably wrong cos my thermometer always says 22 C. oh well. hopefully might get some rain or something. steve -------------------------------------------------------------------------------------- From: Dann Weatherhead To: "aussie-weather at world.std.com" X-Originating-Ip: [139.134.93.4] Date: Fri, 13 Nov 1998 01:24:10 "GMT" X-Msmail-Priority: Normal X-Mailer: AspMail 2.62 (SMTP85107B) Subject: aussie-weather: Humidity, and soft breeze Sender: aussie-weather-approval at world.std.com Reply-To: aussie-weather at world.std.com X-MIME-Autoconverted: from quoted-printable to 8bit by penman.es.mq.edu.au id MAA24003 After, the bucketing that we recieved last night(Penrith), their should be heaps of rising moisture which points to one(or several things).

Quite a bit of light rain off the coast from about P Macquarie north though, all moving SE. The storm south of Wgong at 1.50pm has an area about 20km x 5km of >40mm/hour rain from the coast northeast of Nowra extending north. The northern end of the line of storms/showers is still to the north of Bowral, but the activity is all between Wollongong and Nowra -- say around Kiama and Gerringong. I haven't seen radar for a month or so, and I'm a bit disappointed that the BoM doesn't seem to have done any further work on tidying up the map backgrounds. Locations are still just three letters, each a scale 10km high/wide, so working out precisely where things are in relation to anything remotely geographic is still guesswork.

It seems starnge thats all...I mean what did they want in the first place? As I have replied to Jimmys mail: severe weather is not only the physical event, but the hypothetical, and educational. Thats what I believe this list is all about, until the Society is up & running. The we may have a Society email list, which would then circumvent the problems (or supposed problems...it only seems problems to few people). I think that we all have to be a bit pateint & that the emails regarding telling people what or what not to write, is dangerous because of one major reason: its destroys enthusiasm...and thats not good. We are here to not only to talk about current weather /storm chasing but also to prepare future storm chasers. This "gagging" or "censoring" of email subject I think is dangerous.

I am one of those who have CONSIDERED unsubscribing for the group because of the volume of mail. HOWEVER, I find the majority of the discussion so interesting that I have not been able to take that step. A couple of easy problems to solve, for me who recieves commonly at less than 200 bytes per second. Common use of the reply option : recently I recieved an e-mail of 8 lines which I wanted hardcopy of - I printed four pages! The reply option had been used numerous times, so I got hardcopy of six or eight lengthy e-mails which I already had, and had no further interest in. Personal notes of reply: There are numerous e-mails containing something like "thanks jack" which could be addressed to the individual rather than directed through the group. Many of these are also "reply" options, and the system is further congested. On the bright side, the potential problem of attachments seems to have been solved - those image files, interesting though they may be, can really challenge servers. Other discussion groups in which I am involved promote the advertising of available (lengthy) files, and if individuals want then, they deal direct, not through the group. That's my say - keep the interesting info coming. Notice from sat pics and the discussion plenty of activity in the deep south. Good luck to the chasers. Plenty of cloud here, and advised chance of a storm. Actually we could do without it - plenty of outside work to get done. 20 odd mm reported around the district yesterday.

Sender: aussie-weather-approval at world.std.com Reply-To: aussie-weather at world.std.com Hi everyone, With the amount of people on this list, we are always bound to get some disagreement on a few things, but the most important thing we have to remember is the name of this list, being Aussie-weather, anything to do with Australian weather is fine, whether its talking about forming the Australian Storm Chasers Society or storm reports etc.. The short 1 line reply to individuals does add up to the volume on the list, and its probably better to send a reply to the original poster in that case, unless offcourse the reply is directed to everyone on the list. We all have a common interest, which is the weather, that's the main thing. Anyway, rain periods here in Perth today, due to a cold front interacting with cloud coming down from Tropical Cyclone Alision, this is what BoM in saying: Cloud from the remnants of Tropical Cyclone 'Alison' extends over the metro area. Showers and drizzle have resulted from the band and should persist for the rest of the day and this evening. Showers should clear overnight or early tomorrow. Much cooler today than on Wednesday when we had 37.7C, currently at 1:50pm WST its only 16.8C.

It was quite a small cell but did display some interesting features. There was some rotation at cloud base, on the updraft on the NW side, I am 90% certain that the rotation was at base level only and not the result of mesocyclone rotation, but rather clashing outflow - inflow boundaries. None the less it looked great for a while and even took on a hail colour. No hail fell. Now at 5pm I am pretty sure we are on the clearing edge of the trough line, there appears to be very little Cu west of the escarpment ( almost the reverse to normal situation ). A weak cell past just to the SE about 30 minutes ago, whilst another is trying to develop to the NW. There is something missing, the Cu is getting into congestus and calvus stage quickly, and even glaciating, but there is very little anvil building, perhaps an inversion high up, or lack of upper winds. All I know is one ingredient is lacking.

There appears to be a strong upper inversion (has been all day) and the tops of the current activity would be luck to much above 3,000m. I therefore doubt that much will survive the descent over the escarpment to the coast. I measured about 37mm from this event over the last 48 hours but no thunder or lightning activity in this region despite some hopeful looking congestus at various stages..

It's a very active growing list where lots of different people participate. The postings are seriously about weather, and so far we have been relatively free from the kinds of bickering that often takes place on a list. I have always endeavored to let this be your list, and limit my role to be a technical advisor. Having subscribed to or managed several list in the past, I have seen some of the growing pains that this list is beginning to experience, and some of the strategies that others have used to over come some of the common problems that I would like to share with you. Again, this is your list, so use these ideas, or ignore them as you see fit. As a list grows and becomes more active, you will lose some subscribers because of the volume of mail. This is not always a bad thing. Folks who don't want much mail probably shouldn't subscribe to mailing lists. On the other hand, there are strategies that can help keep the mail volume down. Often the issue is not so much the number of postings but the size of them. The only time I was aware of folks leaving the list because of the quantity of mail, was the time that I accidentally approved a message with a 200k picture attached (again, sorry about that). We got 3 of 4 unsubscribes that day. Here are some mailing list traditions that help to keep the size of the post down. 1. Dont include attachments. If you have a picture to share, put it on a web site, and just send the URL (jacob and I will try to help you if needed) 2. Don't send "me too's". These are responses to often long posts where the entire message is quoted followed by a line saying "me too!" It's better, for instance, if you agree post, send a message back to the list with the subject line: Re: Administrivia: Re: Mail to this List...(long) and just say: "I agree" (or any other thing you wish). Quote the original message if it is short, or if you are only responding to certain parts of the message (I that case only quote the parts that you are responding to, and for the other parts insert: [snip] 3. Send messages only in plain text (ascii). Dont use html or MS-Word formats. These almost always take up more space. Again if you have problems getting your mail software to send plain text, contact jacob or me and we'll try to help you out. There might be an odd instance where plain text wont work (like with table, where ascii won't always keep things lined up right). In these cases put formated text on a web space and include the URL in your message. 4. Dont include the signature or footer if you quote a message. In other words, if you were to quote this message in a reply, delete the "David Hart" (it says that at the top) and dont include the: +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+ To unsubscribe from aussie-weather send e-mail to: majordomo at world.std.com with "unsubscribe aussie-weather your_email_address" in the body of your message. -----------------------jacob at iinet.net.au------------------------------ The list will automatically add that to the bottom, and only one is needed. 5. Don't start the message by telling us who you are and where you are from every time . The message tells us the e-mail address that it came from. It might not be a bad idea to include a couple of lines at the bottom of the message with your real name and where you are from. This is called a signature, and the tradition on signatures is that they should be less than 4 lines. (look at the bottom of this message). Sometimes the issue is not so much the volume of the mail, but the volume of the mail that one is not interested in. With weather, just like most other things, people will be interested in some categories and not in others. The trick here is to use the subject effectively. If you have a message about fog in Tasmania, put "Fog in Tasmania" in the subject. That way Tasmania fog fans can go right to that, and those who couldn't give a fig about it can ignore it. There are certain subject line protocols that have been used in mailing list to give subscribers a hint as to what's in a message with out having to download it a read it first. Here are some traditional ones: Administrivia: This is for messages that deal with how the list operates, not the topic of the list (aussie-weather). This message is an example of that. off-topic: If one felt that they wanted to send a message about something that had nothing to do with the topic of the list. If someone wanted to post a comment to this list about the recent Australian elections they would put in the subject line: off-topic: Australian elections You can also develop conventions your own conventions that are suitable to the topic of the list for instance you could use: SVR-WX: for thunder-storms and tornados Tropical: for messages about Cyclones and the like. OBS: for observations or WA: for information about Western Australian weather. One other suggestion that will reduce the amount of mail of no interest to the general list is to send message aimed at one person or a group of persons, is to send them private e-mail. Finally, if you have a very long message, its not a bad idea to warn everyone that it will be lengthy by adding (long) to the end of the subject. I apologize for the size of this mail, but I hope there will be some information that you will find useful. Again, this is your list so use these ideas or not, and you see fit. -- David K, Hart Boston MA, USA -- -------------------------------------------------------------------------------------- From: disarm at braenet.com.au X-Sender: disarm at braenet.com.au (Unverified) X-Mailer: Windows Eudora Pro Version 3.0 (32) Date: Fri, 13 Nov 1998 18:25:34 +1100 To: aussie-weather at world.std.com Subject: aussie-weather: storm Sender: aussie-weather-approval at world.std.com Reply-To: aussie-weather at world.std.com a storm cell is passing over south/ south west sydney right now, some nice CG lightning,a couple even pulsating for a second or 2.. this is the only action all day around here... -------------------------------------------------------------------------------------- From: wbc at ozemail.com.au (Laurier Williams) To: aussie-weather at world.std.com Subject: Re: aussie-weather: Storms!!!

I left work just before 3pm in the hope of some action. Earlier, a line of congestus from Bowral to Wollongong (directly south of Sydney area) developed with a large thunderstorm cell on the eastern edge by about 1.30pm. The tower was capped by an extensive pilleus formation, but became obscured by cumulus in the metro area. I was hoping that a trough line was to out south and would move north into the Greater Sydney area, but it was not looking promising on the short train trip home. Scattered moderate to large cumulus dominated the sky line, the temp was in the mid to high twenties, and the wind a moderate NW-NE. Jimmy picked me up at 3.30pm just as some congestus formed to our immediate SW. It was a dash to get the gear from my place then on to Rooty Hill. Unfortunately, the activity had virtually collapsed by the time we got there, although a distinct line of larger cumulus was evident stretching from the western suburbs to the southern. We waited and hoped that one of the larger clouds would grow..... At around 4.40pm things started to happen. A large clump of cumulus to our SW began to punch higher. Jimmy wanted hail! We took off! Racing south, then west, then south, then east, then south and east again was made it under the base of the flanking cell of a line of activity stretching to the ESE. Location: Austral (undeveloped area west of Liverpool) Time ~5.20pm. Close CG's crashed around us as precipitaion took over the area. Intense rain reduced visibility to under 50m as we pressed on to the east and south remaining under the rear cell. YES - some hail fell. Small stuff only and it didn't last long, but boy did the rain continue. Roads were awash as probably 30-40mm fell. We ended up and Glenfield as the storm edged clear of us, then headed back west a little to Crossroads (where the SW freeway begins). Time about 6pm. What an awesome sight greated us! A massive updraft boiling overhead, a lowered base with indications of low level rotation, intense lightning, perfect contrast for photos, a rainbow and rain/hail shaft! What more could we ask for except a tornado...being in the exact right location (NW flank) for one to form it was on the cards. We watched in awe as the storm slowly moved away to the ESE, the low level features persisting and a back shearing of the anvil becoming evident. We only moved on after congestus forming to the west started to obscure the view. On the way back to my place (which is about a 45min drive from where we were) it became apparent that new activity was developing in virtually the same location as where the earlier storm formed. We headed up to Horsley Park Hill only to discover David Croan and Paul Graham in awe of what had just passed to their south. (they had seen us earlier make a dash from Rooty Hill, but we were too fast for them to catch us and remained at Horsley Park Hill). Chaser convergence - the first occurrence????? We watched and chatted as the next storm system organised to our west and SW. Close CG's and a rapidly developing rain shaft approached us around 7pm. The sunset lit everything up specatularly. The main part of the storm passed to our S, however an updraft developing overhead soon started to pelt us with rain and some strong winds as well. Awesome base lowerings occurred as it moved to the east while lightning struck close by. The rain persisted in our location before giving us the opportunity to take in the beauty of the storm edging away. We stayed on the Hill till about 8pm taking the oppotunity for lightning photography. I'm not sure at what stage either of the storms became severe, but they were not when we encountered them. The first storm had very little wind, but the rain could be classified as severe. The second storm did have strong winds and very heavy rain, but no hail at our location. regards, Michael A happy chaser!!!! -------------------------------------------------------------------------------------- From: "Michael Thompson" To: Subject: Re: aussie-weather: Sydney Storm Chase 13/11 Date: Fri, 13 Nov 1998 22:50:45 +1100 X-Msmail-Priority: Normal X-Mailer: Microsoft Outlook Express 4.72.3110.1 X-Mimeole: Produced By Microsoft MimeOLE V4.72.3110.3 Sender: aussie-weather-approval at world.std.com Reply-To: aussie-weather at world.std.com Tomorrows outlook is not that hopeful, yet the Hunter forecast is still suggesting storms.

Thanx for the fax about the Sandon tornado. I've a couple of questions about it though. Who is David A.J.Seargent? Is he Bureau, researcher (both?) The extracts look REALLY interesting! Does he mention the Tongala (Victoria) tornado, in 1977 if memory serves, or the Bendigo tornado in (now my memory gets hazy..) 1980/1? I managed to get to the Tongala site the next day, as relatives who lived there told me about the whole thing. Eyewitnesses told me that it came in from the WNW and straight winds nearly blew the windows in. One hundred metres south it took the local hardware store and "effectively relocated it", along with the local Catholic school. There may have been a family of cells associated with this event, because a caravan park (not trailer park :)) was devastated in Echuca about twenty minutes earlier. Tongala and Echuca are about twenty k's apart. I saw the results the next day...A gum tree that it would have taken two people to join hands around was uprooted, straight out of the ground, and deposited very neatly thirty metres away! (That was in Tongala, north side). P.S. I hear you've been chasing. Hope to get some 1sthand reports! Yours, Kevin Phyland. -------------------------------------------------------------------------------------- X-Originating-Ip: [203.25.186.101] From: "Kevin Phyland" To: aussie-weather at world.std.com Subject: aussie-weather: Hail=green Date: Fri, 13 Nov 1998 04:22:26 PST Sender: aussie-weather-approval at world.std.com Reply-To: aussie-weather at world.std.com Hi every1, I've seen a couple of references on the list to green optics and hail and having seen a few myself (Gold Coast about six years ago and locally about four years ago) was wondering about the physics of it. It's not an optical illusion (I don't think) and I was wondering whether hail bends light differently to raindrops. I think it does but I'm not sure how! There is a definite dark green hue to the low-based storms that I've observed that produced lots of hail. They've all been when I've been facing west (oddly enough) in late afternoon. Yours, Kevin Phyland. -------------------------------------------------------------------------------------- From: "Dr Martin Davey" To: Subject: aussie-weather: Re: " Gully" wind effect in Melbourne. Date: Fri, 13 Nov 1998 13:52:00 +0930 X-Msmail-Priority: Normal X-Mailer: Microsoft Outlook Express 4.71.1712.3 X-Mimeole: Produced By Microsoft MimeOLE V4.71.1712.3 Sender: aussie-weather-approval at world.std.com Reply-To: aussie-weather at world.std.com I was reading with interest the description of the " gully " wind effect or tunnelling of winds from the SE in Melbourne yesterday. In Adelaide " gully " winds are very common in the Eastern Suburbs in the Summer months. Apparently they are due to an " inversion" layer of air which then tunnels down through the hill gullies. When there is a south - easterly airstream the winds can be very strong, even gale force. It is quite an interesting wind in that it only occurs at night and is very localized to the foothills and nearby suburbs. While the wind can be close to gale force in the foothills it can be perfectly calm at the top of of the hill and some distance away from the foothills eg in the northern suburbs. I have travelled quite extensively but haven't come across this phenomenon much. Does it occur in Melbourne much? Does anyone know where else such unusual winds may occur?
