Ah Well,
They all passed me by (sigh), just a few light showers at Mt. Crosby, but
it is still quite spectacular to the South, with a large storm now in the
Beaudesert region and a small cell pretty much over Anthony's place.
Lightning rates have picked up to around 80 every 5 mins, and there is
plenty of rumbling.
John.
>snip
Hi All,
Lightning to the SW, W, NW & N at Mt. Crosby, frequency approx 1 per 10s,
getting close, closest so far approx 15k's. Lightning Tracker has up to 50
per 5 mins in the SE region. Storm near kyogle has dissipated (ref: NSW
BoM Storm Warning).
Now raining.
Regards,
John.

Firstly, we just had a hailstorm go over here...with thunder audible
from 10pm, and slowly getting louder, as well as more frequent
lightning, I was considering turning off my computer. But mother nature
did that for me, by creating a large power surge that reset it :) After
that, it was a nice lighting show, 5-10s apart (only sheet though) but
certainly some nice thunder, and very heavy rain. And of course, pea
size hail to top it all off!!!
Also...Ben and I went storm chasing down south, we saw some nice cells
(including the one that presumably hit Kyogle, it had some very nice
structure). Lots of nice little cells, almost too many (could not
decide which one to chase). Unfortunately, many cells decided to sit on
the border ranges, so this made observing base features difficult.
Should have a report + pictures up in the next few days...

Hi Andrew and others,
>From my years in Perth, the term 'cock-eyed bob' was generally used in the
media to describe a severe winter storm cell causing F0..F2 damage along a
narrow path. Most definitely a vortex associated with a thunderstorm cell,
however, I wouldn't be surprised if the term has been incorrectly applied
from time to time to refer to damaging local squalls (i.e., straight
winds).
Known also as "coldies", some interesting facts present themselves, these
events generally occur in wintertime associated with frontal activity or
post frontal activity in southern ocean depressions. The weather is
usually very squally with scattered storm cells. The storms are not severe
electrically as we in the Eastern States are accustomed to and have nothing
like the same vertical development. They are generally fast moving in
conditions where there are strong westerly winds with high levels of shear
and there is no large change in wind direction during the passage of these
storm cells (i.e., < 45 degrees). They can also occur in tropical
depressions where similar high wind & high shear conditions exist (e.g.,
near Noosa QLD last Feb) and are known to occur in the couldbands
surrounding a tropical cyclones and hurricanes.
These conditions seem to be quite different to those we would normally
associate a Tornado with, i.e., violent supercell thunderstorms associated
with summertime troughs or 'dry lines', and also rather different to those
we would normally associate a waterspout with, i.e., a non-storm bank of
slowly drifting cumulus. While 'coldies' do tend to occur close the coast,
I do no believe that they are merely waterspouts. Personally I think that
the conditions and event are sufficiently unique that they should have
their own name (I guess they have).
Curiously, despite the fact that they are relatively frequent in certain
parts of Australia, particularly SW WA, no photo exists as far as I am
aware.
Ira would probably have something to say about all this.
John.

John,
There was a 12 year old girl recently that got a pick of the last nader
that hit the rockingham area a month or so back. Ira does know of who this
young girl was that took the picture of the nader. As her mum sent a copy of it
to the BoM which is how we found out about it, From Barry at the BoM severe
weather section Perth.

Hi Mark, Kevin and others who'd like to chime in,
Mark Hardy explained:
#In the Australian article they did draw a line. Mini Tornadoes form in cold
#air thunderstorms, mostly winter and seemingly near the coast. (real)
#Tornadoes form in hot humid air. They quoted Perth meteorologist Adrian
#Redmond.
[snip]
I am dazed and confused. Is a "Mini Tornado" a tornado or is it a different
beast altogether? I am guessing a "cold air thunderstorm" is a storm
with very cold air aloft and a steep lapse rate below that - would
that equate a Mini Tornado with a cold air funnel? Is there a BOM person
out there with all the answers?

I was woken up by another storm cell at around 3:20am this morning.
>From the look of the current radar/tracker, it appears that
thunderstorms have continued all night in the SE QLD district. However,
this has moved out to sea, but it has formed a nice rain band, and is
moving towards to coast slowly in a SSW direction. At 7:16am there were
50 new strikes on the tracker.
A rare (almost thought impossible) treat to receive so many
thunderstorms in August, if you take the 3:30am storm to be another day,
then that is 3 consecutive thunderdays in a row - in August! On Friday
night, a small cell developed over the southern suburbs and gave some
nice lightning, thunder and heavy rain. Certainly this cold pool has
been very nice!

There is no such thing as a "mini tornado" - it was simply a term used
for the media to explain the phenomena of very strong thunderstorms
(which were either associated with microbursts/straight line winds, or
tornadoes). To say "MIRCOBURST CLOBBERS CITY" sounds rather meek, and
the average person would not know what it means. Or to say "TORNADO
CLOBBERS CITY" sounds like fiction to the media, because of the (very
dangerous) myth that tornadoes do not occur in Australia. I think what
others are trying to say, is that, could it possibly be that
tornado-like phenomena (waterspouts, dust devils etc) could be akin to
what a "mini tornado" would be like (if there actually was such a
phenomena). A tornado is a tornado, be it an F0 or an F5.
Back in the pre 1900's and early 1900's, most severe events were called
"hurricanes" - although one would wonder if something would be wrong, to
have 20-30 hurricanes pounding SE QLD each year... As time progresses,
calling severe thunderstorms "cyclones" became the fashion, and in the
1940-1960's, severe thunderstorms were called either cyclones or
typhoons. Now we're in a new "era" were severe thunderstorms are called
"mini tornadoes" or "mini cyclones" which is really just a term to make
a storm sound better, to sell more newspapers, or to get people to watch
the news.
I hope this helps!

Hi All,
After the nice storm and chase from 3pm onwards yesterday, there was
distant flashes of lightning in many directions welll into the evening. I
went out again for a few lightning pics at 8.30 - 9.30pm, but most of it
was too far away, though still got a few pics. Fog was quickly developing
in the valleys around here, and I saw the hill in front of me become
enveloped in fog in about 30 seconds!
Lightning and rain spread in from late evening and it became very active
around 2-3am with some moderate falls. One CG hit very close to our house
with almost simultaneous thunder and a brief blackout. I think the
lightning continued till about 4am, but not sure after that.
So three storm days in a row here also, with activity on Friday S of me and
into the Evans Head area.
regards, Michael

That reminds me of the time not long ago when a currawong (I presume)
regurgitated its tummy into my rain gauge, (seeds and liquid) , which
made it terribly hard to derive the rain reading for the day!

There have been some "nice" rainfall totals with the storms observed by
Michael. The Channon (east of Lismore) had 40 mm in 35 minutes from 3.25
pm yesterday; Lennox Head reported 41.5 mm in an hour from 5 pm and
Pepentance river 28 mm in the hour from 3.55 pm.

As I write a huge mist is comming in from the east here in Taralga. We've
got very gusty E winds with associated occasional showers at the moment -
typical "easerly" weather. As expected the radar isn't picking up our
precip. WHAT'S THIS LOW THAT'S EXPECTED TO FORM OFF THE N COAST GONNA DO?

Hi all,
Pretty interesting here at the moment. The mist has rolled in from the east
with moderate, blowing drizzle comming in squalls. The wind is gusting at
around 50Km/h, pretty damn strong! I don't know how local this is because
the only wind warnings are for costal waters north of Wolli, but it's pretty
blowy here I can tell you!
Just about to check the Aviation Forecasts...
Andrew.

I just got a call from Matt Smith that he heard on the radio that just
after 2am this morning (2:18am) there was a tornado?? that left a narrow
path of damage to about 25 houses or so. Details are sketchy but as more
information unfolds, we will try and post to the list.
The synoptic conditions is unusual as it is more of the NE airstream type
of weather. There were some localised large cumulus and cumulonimbus during
the night with rain and local heavy rain. I would say that the cells
developed over the land in the unstable airstream here and there as
observed on the radar.

At Schofields, it took some time for rain to commence but we finally got

There's definately some on and off cells about there, there was pink on the
radar about 20 mins ago just east of Bankstown which disappeared as quickly
as it came. I'll be very interested to hear more...

Hiya all.....
Evans Head received 54 mm. 5 miles south at the AWS only 25mm was recorded.
It appears the cell yesterday afternoon/evening moved out to sea over
Lennox Head and then brewed there for several hours. I watched it last
night from 10pm northeast of here out to sea, and then it headed south
along the coast hitting here at 2am. Heaps of lightning but light winds,
and heavy rain at approx 25mm/hr. There was a smaller storm cell which
broke away to the southeast at the time and sat just over Yamba/Iluka. The
Evans Head cell hung around for 2-3 hours. Currently there is thunderstorm
activity and heavy rainclouds consolidating to sea, and the wind has turned
sharply from the northeast to the south in the past 30 minutes. It appears
as though an upper trough is keeping this event active in the northeast of
NSW this morning, and more thunderstorms are quite a possibility

Hey everyone,
Yesterday i observed some strong cells, but it seemed the updrafts, while
large and quick seemed to die once they had reached their 'peak'.
Last night we had typically drissly night with only 2mm til early this
morning. However, from 7am onwards we were hit with heavy shower cells. We
recieved 14mm, including heav downpours in the last hour.
However as quickly as they came, they have gone, and bright sunshine greets
us. Maybe I can get some painting done.

The weather in the northeast of NSW has taken a dramatic turn in the last
hour along the coast. While the Grafton Radar indicates most of the rain
and thunderstorms are coming in from the north east, winds on the ground
are blowing from the SSE gusting to 30 knots. This has brought with it
heavy rain along the coast, and the viz to sea is still very black. There
is a strong possibility that if these conditions persist over the next 24
hours the Northern Rivers region (The Wilsons River especially) could be in
for minor and perhaps moderate flooding. This will depend on how far the
S/SE wind pushes the moist air inland onto the ranges. I would not be
surprised if minor coastal flooding extends down to Coffs Harbour. In the
Clarence it appears on the Grafton radar that the Nymboida and Orara River
catchments are receiving rainfall but it is not heavy enough to cause
problems.
Will keep you posted (as thunder crashes overhead)

We've had thunder very close by in the past hour (currently 11.10am at
Wollongbar) with moderate rainfall. Radar (when the bloody Grafton local
one works!) shows extensive heavy rain spreading in from the NE with the
lightning tracker also confirming movement towards the SW -SSW. Low level
winds are S-SE and have freshened (as Halden has just posted).

All the Sydney wind AWS's seem prone to spikes like this -- Cannae

I remember some spectacular radar images from Giles last November (I
think) with great gobs of red cutting off into virtually clear air.
Whilst a few thunderstorms were reported in the area, they didn't
account for the nature of the image, and I remember some discussion on
the list which concluded that dust storms were responsible given the
high reflectivity of dust compared to rain. I guess this is a
condition we need to watch in all arid area radars.

We've had a succession of heavy showers at Blackheath since about 3am.
I had 19mm in the gauge between 2100 last night and 0900 this morning,
and a further 11.4 in the further 2 hours to 11.00. I note that Sydney
radar only shows the odd patch of dark blue in our area during that
time, so either the mountains are causing it a problem or the vertical
zone of heavy rain is lower than the beam angle at this point. I think
this is probably the same problem as yours, Andrew, though I haven't
noticed such a great discrepancy before.
As to a low developing off the coast, none of the present models seem
interested with the possible exception of last nights meso-LAPS run
which has a possible low developing east of about Brisbane, but as
it's right on the margin of the SE Australia panel it's a bit hard to
tell whether it's a low or just a tightening trough. All the models
agree on heavy rain continuing on the SE Qld and N NSW coasts for a
few days.

Susan from Balmain here.....
Was driving home from North Bondi last night (Saturday) around 1.30am. Left my
friends house at that time - drove down into Rose Bay when the rain started -
just light rain - by the time I got to the Kings Cross tunnel on William Street
it was bucketing down very heavily - I have efficient wipers on my car, blades
are only a month old - by the time I drove out of the Kings X tunnel the rain
was torrential, my wipers werent
handling the rain load and the road was covered in 4 inches (approx) of water -
had to pull up for around 20 mins and wait for the rain to ease - couldnt see
the lane markings - couldnt see more than 10 feet ahead of me. By the time I
got to Balmain it was barely spitting rain.
I have driven in a lot of heavy rain but in my experience that was the heaviest
I have ever driven through.
Anyone have any information on how much rain we got in that short burst around
the city - kings x area?
Susan

Since 9am Evans Head has recorded 27mm. Winds remain from the SSE however
they have abated slightly. There have been very heavy showers ranging in
from the ocean, and there is still a line of thunderstorms out to sea. The
radar weather indicated the storms are still coming in from the
northeast....however wind on the ground is opposing their movement, real
seeing them dumping mainly on the on the coastal belt.
The electrical storm line according to Energex data over the past few hours
is starting to rotate clockwise......and there is still a big band
extending from Evans Head to off the Gold Coast about 10-20 nautical miles.
The Tweed Valley appears to have received a good soaking of rain...with the
band heading SW. This could lead to creeks in the Upper Wilson's River
releasing a fair laod of water downstream as perviously predicted (1030).
As well rain activity in the Bungawalbyn catchment could see some rises in
creeks in the region southwest of Lismore/Coraki (known as the south arm
of the Richmond River).
As I speak anouther thunderclap rumbles overhead.
The overview......the SSE airflow over the ground on the coast appears to
be rotating this big band of storms in a clockwise direction. I anticipate
that the Lismore region to the north and the south will receive significant
rainfall overnight as the dew point consolidates the moist air, with
possible minor or nuisance flooding as a result.

As you all know there was a very severe localised storm in the early hours
of the morning (just after 2am) in the Fairfield West area.
I decided I would go and investigate what this might be as it seemed very
interesting in the way it was described by the media.
From first sight, you blinked you would miss it. Once in the area, I could
see that it was very localised with some houses untouched but branches,
trees, garden houses, roofs of carports totally lifted up and thrown along
the path. One tree according to the SES was totally destroyed and partly
thrown one way and other parts thrown across the road. There were branches
found 100 or so metres away. A roof tile was wedged into a fibro garage.
Fences were flattened. TV antennas were bent mostly in the direction of the
of the path but some opposite. Some walls were blown through but basically
fibro or weatherboard structures. All this was within the path of 30 or so
metres. Extremely confined. Absolutely nothing either side except for the
odd smaller road signs bent over. To me there seemed to be slight evidence
of convergence but again it is better seeing it from the air.
the damage was mainly confined to a small area,
around Lynesta Avenue, Beale Crescent and Royalston Street,
Mr Ryan said.
Reports from talking to people who were absolutely willing to talk
suggested that there was very heavy rain and then a noise with a sudden
wind which lasted around a minute (but I think this is speculative probably
under a minute). One person and his family hid in a small room as they
whole house was shaking. This man heard the roar coming down the path as
the whole building started shaking. Most that I interviewed suggested they
were awoken by the violent rain or a loud noise like the sparking
transformer and power lines. One interesting feature was a house that had
one wall cracked and slightly dislodged from the rest of the house which
was due to this event!! There were glaziers there most probably replacing
cracked or smashed windows.
I was interviewed by channel 7. I told them about ASWA and in the
interview, I mentioned there is really no such thing as mini tornados.
It was either a tornado which involved convergence flowing in at the
surface or a microburst which was air falling towards the ground and
spreading outwards. The again asked me what they thought it was but I again
said I had to study the situation a little more.
So watch channel 7 tonight and see if it features ASWA!!!!

Hi all,
James told me earlier that rooves were damaged by lightning...but on the
radio, one house was reportedly "blown apart by lightning" - a dozen
homes nearby had damage to rooves. Hmmm...this doesn't sound like
lightning damage to me! But we'll see, hopefully the news will have
some photos of damage. Apparently, the windows, walls and ceiling have
been blown out on one home. The SES has commented that it was fortunate
that no one was in the house at the time.
This occurred at Labrador - Steve, perhaps you can provide more feedback
on this?
Some Brisbane suburbs were blacked out by the storms last night too.

Hi Everyone
I also went to inspect the damage from this storm. Alot of it had been
cleaned up by the time i arrived, but its great that Jimmy got there early
and looked around and interviewed people. A few small tarps on roof's,
small tree's down in a park linking 2 streets, lots of leaf debri, branches
hanging from tree's and 2 small tree's with the top branches missing, yet a
tree next to them was unscathed. As Jimmy said, very localised damage. My
thoughts are towards a landspout that touched down breifly, or a weak F0
tornado, going by what I saw, and Jimmy's report of damage below. If it
was, I am pretty sure it moved in a E-W path or there abouts. 2DayFM called
it a Mini Tornado, JJJ called it a mini cyclone... *sigh*, Only if it had
happened 9 or so hours earlier when Jimmy and I were chasing....

Everything is settling down here very suddenly. The wind remain sse at 20
knots gusting to 30 but the rain has eased considerably. This will probably
meen the ground will be re-saturated waiting for the next event. The chance
of flooding albeit minor appears diminished.
Rainfall total Evans Head township since 9am local is 31mm.

Colleagues....
I am off to bed after a big day here.....as previously posted the rain has
eased considerably.
However, as predicted there are some unofficial reports (pretty official to
me) of minor flooding warnings from three centres in the Wilsons River
catchment.
* Repentance Creek north of Lismore there is an unofficial warning of minor
flooding after 43mm of rainfall in the area over the last 24 hours
* The Channon is unofficially warning of minor flooding after 52mm of
rainfall in the area over the past 24 hours.
* There is an unofficial warning of low level coastal flooding in the Lake
Ainsworth area (Lennox Head) right on the seaboard after 41.5mm onite in
the Michael bath storm cell... over the last 24 hours 97.5mm has fallen
possibly causing localised flooding of roads etc around Ross Lane.
After everything settles there is a good chance of a "fresh" in the
Wilson's River of up to 2 metres....possibly tomorrow 9am at Lismore.
Coraki should get the fresh at 9pm tomorrow night. Depending on my
observations of the Bungawalbyn storms today Woodburn should be up about a
metre at 9am on Tuesday. Tidal influences will determine the actual
recorded heights. I predict about 2.1 metres.
Thanks for the patience today....it's not always you get an event like
this....triggered by Michael Bath chasing that stinking stormasaurus
yesterday and giving it the irrates to do more!!!!
Cheers Halden

Cool Jimmy, that might get us some recognition from other organizations out there
i.e. the BoM and the media. Which should be good for membership for ASWA, and
hopefully it will help us increase our membership numbers. It was also good that
you put the media in there place on the "mini tornado" subject aswell !!!!!.

THE AUSTRALIAN SEVERE WEATHER ASSOCIATION INC WEEKLY NEWSLETTER -Issue 5
The Australian Severe Weather Association Inc (ASWA) is here to provide a platform for discussion into severe weather, research and education. A lot has been written about about Australia's severe weather in the past and you can view many different stories of people's experience with the weather in the offical ASWA magazine "Storm News". Discussion about the latest weather and a great place to learn from is the aus-wx mailing list from which ASWA Inc was originally formed. The mailing list is filled with people who are eager to help teach others about all aspects of meterology and to share their experiences.
Membership into the ASWA Inc is $30 a year (with access to the Bureau of Meterology's radar and a quarterly subscription to "Storm News) or if you don't wish for radar $20 a year (with the quarterly subscription to "Storm News" still remaining.) Both visitors and members are welcomed to attend State Meetings. State Meetings are held in Western Australia, South Australia, Victoria, New South Wales, and Queensland in their capital cites. Members can also have the chance to buy an ASWA T-shirt in either polo or round neck styles. If you would like to join you can visit the ASWA Inc website at http://www.severeweather.asn.au/ and fill in an online application form or get in contact with your State Rep. All details can be found at the website.

The house was pretty well stuffed by what I saw on TV tonight........they
said that the TV antenna got hit, but when they showed it, (the antenna),
there was no tell-tale lightning damage (melted ant. elements etc.)......I'm
wondering if the bolt touched down on a nearby tree & 'bounced" into the
house.
See ya's
John
