Currently in Brisbane the conditions remain pretty much unchanged since 11am. About 22C...90% humidity and only light 'spitty' rain falling. A northerly at about 15kn has sprung up though. It would be good if that cloud cleared early for some nice a'noon storms...but we're not that lucky.

Cobar registered 60mm 3 to 9pm of which 5 was in the gauge at 6pm, 27.8 at 7pm, and 56.4 at 7.43pm. The Met Office at Cobar, which curiously is in the town, not at the airport, had 41, all falling 6 to 9. Glen Innes had 16mm 3 to 9, and on the Mid North Coast, Evans Head had 30mm 3 to 6pm. In Qld, Longreach had a big dump just after 6, with 22.2 in the gauge by 6.45pm, 11.0 falling in 10 minutes to 6.43pm. Lots of other heavy/storm falls in Qld during Sunday -- can you Qlders tell us any more about it? On the forecast front, the MRF for 00z Sunday still holds with very cold air moving over Tas/Vic/southern NSW Tuesday morning (528 thickness line crosses the Gippsland coast), heavy rain in eastern Qld not clearing until Tuesday, and a return to storms/rain through inland Qld on Friday. Tots is >60 over southwestern Qld for 00z Monday. -- Laurier Williams Australian Weather Links and News http://www.ozemail.com.au/~wbc/ -------------------------------------------------------------------------------------- Date: Mon, 26 Oct 1998 09:00:02 +1100 (EST) From: Paul Graham To: aussie weather Subject: Re: aussie-weather: Weather photos 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 On Thu, 22 Oct 1998, Mark Hardy wrote: > We would like to obtain some exciting weather photos to be made into some > introduction slides on the channel.

I just inquired about having a storm photo which appeared in a Sydney newspaper put online (either Michael and Jimmy's page or one of my own) and was quoted $75 for 6 months or $120 for a year!!! Just for one lousy storm photo (funnel cloud) and he said there were 4 rolls of film for this storm... Imagine paying for the whole lot - you'd be into the $1000's - Paul G. ---------------------------- Paul Graham m3052695 at hardy.ocs.mq.edu.au ---------------------------- -------------------------------------------------------------------------------------- X-Sender: mbath at ozemail.com.au Date: Mon, 26 Oct 1998 09:33:58 +1100 To: aussie-weather at world.std.com From: Michael Bath Subject: aussie-weather: CSIRO NOAA satpics Sender: aussie-weather-approval at world.std.com Reply-To: aussie-weather at world.std.com Just to let you all know that the 1.1km resolution NOAA AVHRR images are back online after 48 hours out of action: http://www.marine.csiro.au/~lband/storm/ regards, Michael *==========================================================* Michael Bath Oakhurst, Sydney mbath at ozemail.com.au Australian Severe Weather http://australiansevereweather.simplenet.com/ *==========================================================* -------------------------------------------------------------------------------------- From: disarm at braenet.com.au X-Sender: disarm at braenet.com.au (Unverified) Date: Mon, 26 Oct 1998 11:47:34 +1100 To: aussie-weather at world.std.com Subject: aussie-weather: sydney forcast today Sender: aussie-weather-approval at world.std.com Reply-To: aussie-weather at world.std.com IDF00N00 METROPOLITAN FORECAST BUREAU OF METEOROLOGY NEW SOUTH WALES REGIONAL OFFICE Issued at 11:25am on Monday the 26th of October 1998 For remainder of today and Tuesday Sydney Metropolitan: High to very high fire danger.

Some impressive cells with extensive anvil development to the NW through to NNE of Canberra (at least 100 km away - so won't be affecting Canberra itself). Some more isolated developing cells to the SSE to E with signs of glaciation. A few showers on the ranges to west but tops don't seem to be very high so not expecting too much in Canberra itself. Next Saturday's NOGAPS (12z) looks pretty interesting ... but is a long way off at the moment. ______________________________________________________ Get Your Private, Free Email at http://www.hotmail.com -------------------------------------------------------------------------------------- From: Blair Trewin Subject: Re: aussie-weather: Current Melbourne weather To: aussie-weather at world.std.com Date: Mon, 26 Oct 1998 14:14:04 +1100 (EST) Sender: aussie-weather-approval at world.std.com Reply-To: aussie-weather at world.std.com > > Melbourne > 3Cu/5Sc > 16.4 deg > Pressure: 1006.2 > Light shower to the SW at Laverton. > > Boring, boring...... > > Jane Might be boring now, but most progs have thicknesses below 532 reaching Melbourne in the next 12-18 hours.

Maybe they require reports from a "Storm Spotter" before a warning can be issued or perhaps they decided that by the time they were to issue a warning, it would all be over. Or perhaps it didn't match up with radar and other data they get. Remember the Good Friday storms here in Sydney - they issued a severe thunderstorm warning when it was almost over. - Paul G. ---------------------------- Paul Graham m3052695 at hardy.ocs.mq.edu.au ---------------------------- On Mon, 26 Oct 1998, Mark Hardy wrote: > Is not issuing a warning AFTER near 100km/h gusts have occurred akin to > shutting the gate after the horses have fled??? > > ---------- > >From: Paul Graham > >To: Aussie Weather > >Subject: aussie-weather: Latest... > >Date: 26 Oct 1998 16:03 > > > > >Sky very dark and looking quite spectacular: Steve Symmonds said he would > >be talking to people in severe weather about a possible warning given the > >reports of winds close to 100km/hour in areas.. > >- Paul G. -------------------------------------------------------------------------------------- Date: Mon, 26 Oct 1998 16:51:51 +1100 (EST) From: Paul Graham To: Aussie Weather Subject: aussie-weather: NSW Weather Forecast...

Warm to very warm with moderate to fresh north to northwest wind ahead of a cooler southwest to southerly change extending through the southwest tonight and reaching the central coast overnight and the northeast during Tuesday. A few showers about the coast and ranges tomorrow but fine over the southern inland.

Promising cells were punching upwards left, right and centre as I viewed them from the top level of a parking area in Gordon. The storm that eventually moved closest to me (it appeared to be a single cell) drifted to the south and was rather high based although it did put out some nice CGs - not sure if it was the decaying stage of the same cell which you had reports on Paul (BTW Paul is Steve Symonds on ABCnews radio?). Anyway made for a few ok photographs (i hope).

I have to remind people we stayed there just down from Rooty Hill to get some hail and whatever. Just heavy rain and severe runoff. Some flashflooding reported in low lying areas. It looked impressive with reasonable footage of the squall hitting us and then the rain but Iw ish there was more. I'd say the peak was just to the west.

Yesterday there was some light rain around, we received 8.1mm overall, no heavy or significant falls were reported nearby. But in other places (as some one already pointed out) they received copious amounts of rainfall. Today it started off overcast, but was 23C by 7:15am with a DP of 21C. The DP stayed in the low 20's today, and by midday it was 28C. It was much warmer then expected only because there were a few breaks in the cloud that caused a "greenhouse effect." That is - the sun's heat and radiation came in, only to be kept in by the other clouds. The sky consisted of predominantly mid and high level cloud. But with the Sun out periodically, I began to get very optomistic about the possibility of t'storms. This however was crushed by around midday when there were clearly very little signs of convection. This surprised me a great deal, as the models indicated good thunderstorm conditions - except from the high levels of moisture in the mid to high levels. But then again, I don't feel that the models have got a good "grip" on the current wx system affecting us, because both MRF and NGP supported falls of over 4 inches in about 36hrs, yet we've only had 8.1! Also, the models have had all the timings wrong. At the moment, lightning tracker has a scattering of lightning strikes between just south of Toowoomba, through to Dalby and up to near another town that I'm not sure what the abbreviation stands for! Currently, the strikes have been fluctuating for the past 2hrs, from 1 strike to over 20 strikes in 5 minutes. BoM is not expecting much, 18UTC obs (6pm here) (just one note, I suggest that perhaps we should use UTC now to avoid confusion in daylight saving times...it's just a suggestion) was 24C, 83%, DP of 21C, 1009hPa, NNE at 20km/h - with towering cu observed. I'm not too sure about towering, from what I can see, there is much more cu around now, but it would bearly make "congestus" in my opinion. I'm still remaining slightly more optomistic, it will remain 24C for a little while, it's far to humid for the temperature to drop much. I'm hoping for a t'storm late tonight - but it's more likely that we'll just get thundery rain. Which I guess is technically a t'storm! Just thought I'd inform you on what was happening up here! :-) Anthony -------------------------------------------------------------------------------------- From: "paulmoss" To: Subject: Re: aussie-weather: Latest...

From: "Mark Hardy" To: aussie-weather at world.std.com Sender: aussie-weather-approval at world.std.com Reply-To: aussie-weather at world.std.com A severe thunderstorm advice is the correct procedure if severe storms are likely. Waiting until reports are received is waiting too long. So many times we see advices issued just after the storms have passed through. The BoM does not wait for storm spotters reports before issuing an advice - these reports are used for verification and nowcasting. Generally the forecasters will have a fair idea of the likelihood of TS activity once the soundings and upper winds are available. Having said that we all know that these advices are often issued after the storms have already caused damage. This severely limits the effectiveness of the warning but does wonders for the BoM verification statistics.

Cumulus developed quickly over the western parts of Greater Sydney from late morning with two areas of congestus forming at this time also: to the far west probably around Lithgow and just to my north. The area to the west became obscured by closer cumulus so my attention was mainly on the cell now developing to the north. At first it was not promising as the updraft was weak and started to spread out as altocumulus towards the SE. But slowly it developed with the NW flank of this weak multicell gradually punching higher and higher. Pilleus formed at various stages. It began to preciptate around 12.30pm as it moved and spread towards the ENE. The clouds tops reached probably to about 8km before some slight backshearing occurred. Unfortunately it became obscured as it moved over the Gosford area. Later the cell intensified offshore and can be seen as the large cell on the latest CSIRO pic at 34 degrees S: http://www.marine.csiro.au/~lband/storm/199810260450.html Not much was happening around western Sydney at this stage (1pm) and it was rather hot in the sun I headed back home to check the latest data. I discovered that showers were moving into the metro area near Camden so I headed back out to Rooty Hill. Just as I arrived it bucketed down with rain from a single large cumulus overhead. This quickly cleared as the approaching 'cell' from the west edged closer. It devloped a nice rain free base on its northern side (close to me) while to its south very heavy precipitation occurred. I watched this cell for nearly an hour as it made its way eastwards and into the inner western suburbs (I guess). At the same time (from 2pm) a bank of large cells gathered on the western parts of the Blue Mountains. Congestus was visible ahead of the line and seemed that Sydney would not miss this one! I left the Hill at 2.30pm as I had to intercept with Jimmy (after he finishes work at 3), then get my car to my wifes work then we could go! It was a mad dash when Jimmy arrived at my place as the storm system to the west was quickly approaching. After many annoying trucks on the way &^! at % at we made it to Rooty Hill (once again) at 3.30pm. Just in time. The storm was now in the Sydney basin and developing a nice structure on its forward edge. A shelf cloud and scuds heralded the ominous looking precipiation core. It sure looked like we would get hail. We could see the intense rain spread through the valley towards us. The wind struck with gusts to around 70km/h I guess then very heavy rain with a little thunder for about 10 minutes. No hail - it was surprising. Flash flooding of streets was common as probably 25-30 mm fell in 10 minutes through Rooty Hill and then Doonside. A few flashes of lightning were visible after the cell passed, but there was surprisingly little. After that it was virtually all over. Light rain persisted throughout the afternoon. Some weak cells became visiable to the far west towards sunset. regards, Michael *==========================================================* Michael Bath Oakhurst, Sydney mbath at ozemail.com.au Australian Severe Weather http://australiansevereweather.simplenet.com/ *==========================================================* -------------------------------------------------------------------------------------- From: "Jimmy Deguara" To: Subject: Re: aussie-weather: events in Sydney today Date: Mon, 26 Oct 1998 21:53:09 +1100 X-Msmail-Priority: Normal 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 Still got my tennis game in too.

I remember waking up and watching a late night t'storm while sitting in bed, when one of the neighbour's TV antenna's got hit by lightning! It was about 20m away (diagonally) it was deafening! The other two experiences where in Malaysia, one was "cool" the other was almost scary. We were driving along and we hit a rain curtain of one of the storms, visibility was almost nill, very soon however we exited this, and there was only very light rain. But there was a series of construction sights along the highway with a few cranes - 3 CG's hit the cranes while we were passing only about 50m away! The other one was at my grandfathers house - we were in the lounge when the house got struck by lightning - but it somehow hit the phone wiring, it went through the phone wiring about 2m until nearby was a metal curtain frame - a spark escaped the plastic covering of the wiring, hit the metal curtain rod - and then hit one of the concrete walls actually chipping out a small piece of concrete! Perhaps what was the scariest thing was that not 2 minutes ago, I was standing right next to that curtain rod. Nonetheless, it was extremely interesting and exciting :-) Anthony Michael Bath wrote: > > As Jimmy has answered, the lightning on that day at Branxton was some of > the closest.

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 Dear Friends, Has anyone had an experience with ball lightning? This is the rarest form of lightning and is believed to form in certain situations when magnetic two magnetic fields are approximately perpendicular (recent New Scientist Mag). I have a few stories of the phenomena: one is from an uncle who used to be in the Air Force. Apparently, one of his colleagues, while flying a RAAF plane over Malaysia, witnessed a fireball drift through the cockpittowards his seat belt. It came very close and shrank in size an he received a large electric shock which caused permanent nerve damage. Apparently it detatched and drifted down the isle of the aircraft (witnessed by all those on board) before floating up to the top of the tailplane and blowing its top off! Another is a vague story I recall a friend telling me of his aunt living in east Roseville here in Sydney. Apparently one summer during an intense electrical storm she witnessed an orange fireball float around her kitchen before harmlessly exploding. A few years ago while I was in Canberra in January staying with family, we experienced a thunderstorm with intense lightning - it also brought some small hail and very heavy rain. I think that the Woden valley may have been flooded because there was a report about the storms the following day in the Canberra Times (and I believe that suburb is prone to flash floods). But what I remember (besides the report on the flooding) was a report of a lady in the southern suburbs who witnessed a fireball in her bathroom! Yet another case of this fascinating phenomena. My biggest fear is that one day I may have the rare opportunity of witnessing this phenomena (not likely) but my camera will be on the wrong settings. In my struggle to correct the apeture and shutter speed I'll miss the opportunity for a rare photograph. Worse still, I won't have my camera ready!! - Paul G. ---------------------------- Paul Graham m3052695 at hardy.ocs.mq.edu.au ---------------------------- -------------------------------------------------------------------------------------- Date: Tue, 27 Oct 1998 02:05:32 +0800 From: Michael Fewings Organization: Edith Cowan Uni X-Accept-Language: en To: Aussie Weather Subject: aussie-weather: Close Lightning Sender: aussie-weather-approval at world.std.com Reply-To: aussie-weather at world.std.com Hi, Mike from Perth. My favourite subject. Lightning. I have had quite a few close strikes. The most dangerous was when I was standing in a paddock about 30 metres from an 25 meter tower (you think that would be relatively safe). Lightning struck the ground about the same distance away on the other side of the tower. This was when I was about 12. Shocked the hell out of me. Since then I have been a more careful about standing out in the open when there are storms around. The closest strike was when I was photographing lightning from a place just out of Esperance called Blue Haven Beach. I was in my car trying to get a photo of lightning striking the tower on Wireless hill about 2 km away when out of the blue lightning struck about 3 metres away. All I saw were little filaments of lightning between me and the waters edge and a very bright arc that struck a bush next to me. The sound (if you could call it thunder) was a squeal similar to a very loud squeaky door closing and lasted for a fraction of a second. Then there was absolute silence. That was too close for me!! Unfortunately it didn't scare me enough to press the shutter release on my camera that I had resting on the window seal finger ready. Many times I have had lightning strike between 100 metres and 500 metres. I am reasonably safe though in my car and very rarely get out of it if a storm is less than 7-10 km away.

The storm had been rumbling around the hills for about an hour before it hit the course. We scurried off the course we had to run about 500 meters in heavy rain there were at least 5 cg falshes with no discernable break between the the lightning and the Thunder. I saw one flash hit the ground only about 100 meters away. It was very scarey. also about 3 years ago on a bush walk from Mt Baw Baw to mt St Gwinear car park got caught in a heavy storm which broke when we were at the very top of Mt St Gwineer( Elevation 1500m) very open rocky area with hardly any trees. Frequent cg flashes with little or no time lag between lightning and thunder,very scarey and very cold with heavy rain hail and temp down to about 8 celsius. Dane Newman.

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 Hello everyone, Somethhing a little bit different: where I used to live I had a much larger garden. Across this garden was strung a longwire antenna for HF (high frequency) radio communications (eg. Short Wave listening). The antenna system consisted of the longwire (about 35 meters) to the back fence and a ground wire which was draped down the side of the house. Both wires entered the house through my window side by side (so they were in close proximity). During intense electrical storms (when the lightning was clost by) I often witnessed a spark jump from the antenna wire to the ground lead due to the electromagnetic field associated with the lightning bolt. This is one reason why you should avoid using electrical equipment during storms. A friend of mine had a similar experience last summer: he left a 240volt extension cord plugged in and switched on but with no devices connected while he was out. During this time an electrical storm came through his area. When he returned home he found there was no electricity available but his neighbours still seemed OK - so he checked the fuse box (should say "circuit breaker box" these days) and found the circuit breaker had tripped. Then he found the power cord: the end was blackened and had melted slightly! He asked me what I thought (he's the physiscist...) and my theory was that strong EMF's associated with the lightning had caused the air to breakdown (ionise) near the end of the cord causing a short circuit to be established: once this had happened, current was free to flow from the mains (since he had forgotten to turn it off) and this caused the end of the plug to melt and the circuit breaker (or fuse) to respond. The moral of the story is: don't leave electrical cords plugged in and switched on during thunderstorms: don't use telephones (except perhaps cordless or mobile) either...Possibly avoid using any electrical devices when the lightning is close... - Paul G. ---------------------------- Paul Graham m3052695 at hardy.ocs.mq.edu.au ---------------------------- -------------------------------------------------------------------------------------- From: "Michael Thompson" To: Subject: Re: aussie-weather: events in Sydney today Date: Mon, 26 Oct 1998 23:47:43 +1100 X-Msmail-Priority: Normal 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 Jimmy has, and only just recently at Storm King Dam !!!
