Hi Marty,
Someone please correct me if I'm wrong, but I believe that the JCU sat is a
false colour infra-red pic..... The different colours refer to the temperatures
of the cloud.
White meaning rather cold, and signifying high cloud tops, and storms
(hopefully).
Cheers,
Rosco.

Marty,
Check out our satpic links page:

It has links to many of the JCU images available, plus a link to the
calibration chart to interpret the colours.

Hi All,
Firstly I'm sorry if you get another message similar to this one but None of
my emails from Rocketmail (and Hotmail) seem to be being sent. I sent one
last night but it still hasn't showed up. Oh well just have to write it
again.
After alot of Umming and Erring, I finally decided that it was worth
traveling to the Upper Hunter (Sunday) just to get a glimpse of some
storms. I left St Ives around 12pm and arrived into Singleton just before
2pm. On the way up the was some very nice towers going up to the W of
Singleton. Looked a bit weak at first but seemed to be gaining in strength.
(There was also a nice tower going up near Coffs). I arrived into Singleton
to see what looked like 3 Separate cells all bunched up together W and NW
of there. I encountered the first one 5ks W of Singleton. Certainly looked
great up high with even Anvil but was a bit weak below. Only Heavy rain for
10 Minutes. Not much lightning. But I wasn't complaining it was the first
one I've been in for a while!. The other two cells were towards the NW and
were looking alot stronger. I headed over to Aberdeen which looked to be in
the path of them. On the way I did stop in Muswellbrook and took some great
shots of the two cells and an extremely dark and defined rain curtain.
Correct me if I'm wrong but there also seemed to be some microburst action
from the side of the curtain, pushing the base of it hundreds of metres
horizontally. Some more great shots!
I arrived into Aberdeen at around 3pm and was promptly hit by the first of
the two with still not much lightning and wind but extremely heavy rain and
pea size Hail. The downpour lasted about 15 - 20 minutes and covered most of
the streets and parks underwater. Got some good shots of the flash flooding
with one of the local bowls club who had no greens to play on , just
Water!!!!
At around 3:30pm headed North to the Southern outskirts of Scone to witness
the second of the two cells pass through. This one was alot more organized
with another dark heavy rain curtain (Horizontally shooting out at the
bottom again), shelf cloud (a bit unorganized at first), nice tinges of
green and some great CG lightning. This one hit with a bit more of an
impact. There was a very bright Flash and then spontaneously bang (couldnt
see where) and then a huge gust of wind and very heavy driving rain (some
hail was also observed) The wind was strong enough to break some small
branches off some trees. This lasted 15 minutes until the Hail hit, some
good size around 2cm's. This system passed onto the Barringotn area which is
pretty unpassable. So I had to be content with going back to Singleton. I
headed home down the F3 at 6pm and witnessed some great pulse storms that
shot up in a line running N - S. They looked fantastic with a clean strong
structure and circular anvil but not much in the way of lightning. A couple
of CG's near Wyong and some heavy rain but that was it. Took some more shots
at Sunset. The cloud colour was spectacular red's, pinks, and oranges! Got
home at 8pm
My only down point was that I had ripped the film out of its canister
thinking that it was a 36exp (Manual Camera) but really it was a 24exp. I'm
not too sure how many shots I have lost but Well see when they're developed.
Aggggggghhhhhhhhh!!!!!

The numbers are now in. Aggravatingly, Bellenden Ker (top station)
did not report on February 12, meaning that the 24-hour totals
from the event were lost. The two-day total for the 48 hours to 0900
on the 13th was 1870mm. Bizarrely, this is more than double the
Australian 24-hour record, yet it's not a 48-hour record because
the same station recorded 1947mm in the same circumstances for
the 48 hours to 0900 on 5 January 1979. (I've seen attempts made to
reconstruct 24-hour totals from that event, but nothing that is
officially recognised).
The monthly total was 2506mm, which is nowhere near a record - 5387mm
was recorded there in January 1979 (and 4057mm in February 1977).
Still a lot of water!

These storms that James talked about hit the Manning Valley area at about
7.30pm last night. Some areas received heavy rain, plenty CG hits & a great
gust-front. Taree received decent winds assoc with the gust front (actualy
quite spectacular considering the little activity associated with it). Nice
roll cloud blew in a fresh SW breeze.
Today is looking much better with altocu already present at 7.30am and
masses of it. So heres hoping.

Yeah, it was funny/strange but then they would think that of me. It's
all relative i guess. I had a great veiw of the multi-cell storms out
Oberon way. Developing cumulus, an anvil and then another pettering out
- really interesting. Coming home from Katoomba last night we had to
pull over near Medlow Bath (alt = 1050 metres) as the rain was blinding.
Still, got home to blackheath and there was only 5mm in the gauge. Does
anyone know why Blackheath doesn't seem to get the real heavy falls? Is
it because the storms are often still developing, ie:orographically, and
also because the rain is falling into dryer air or...?

Yes, maybe i did get "licked" by an offshoot from the strike or
something. I didn't want to exaggerate the experience in my excitement
but looking back on the email, i didn't. The sound was so loud it almost
blew my ear drum (and i had the windows closed!). There are some marks
on the Tyre, I'll have to look more carefully though.
We had a strike within feet of the house here last summer. My budgie
fell off his perch and the woman across the road screamed "Sh..!" and
came running outside. It was so loud and there was that strong smell
afterwards. we are so high here on a narrow ridge (around 3600 feet)
and the clouds get very close. Funny thing was during this strike there
didn't seem to be much cloud, it was really sunny. Is that possible?
There was no building thunder or rumbles, just an absolute rock of
thunder and the whole house light up and this really strong smell sat in
the street for a little while.

Lightning was very close. It flashed right next to me, dunno, maybe 0-30
feet. It was too bright to tell exactly.
Very exciting though!

With all of these really great shots starting to turn up, we out here (who
are amateurish in our attempts to produce the same stunning results as you

Please can you tell us (for each shot you post on a site somewhere)
what speed film you used
type of film
f-stop
shutter speed or exposure time for your pics.
That way we can start to get a feel for what works in which situations.

Jane -
I use ISO 100 (better to use 50 but its hard to buy). USE Kodak Gold as its
the best..........
I Use either a bulb setting (which means you hold down the button to keep
the shutter open for as long as necessary or a 15 sec or 30sec setting.
Its important that you either have a tripod and keep VERY still when taking
long exposures or do what I do to trick the camera:-
Put the setting on to self timer (if you have it) and set the exposure for
15 or 30 secs - then you dont get any blurring via movement - only problem
is its hard to capture exact shots - its a lot hit & miss

Hi Jane and all.
I cant resist an invitation like this to promote my site:
http://www.lightningphotography.com/
I have indicated films speed, F-stop and exposure times for most of the
pictures I have, and there is a tips page as well.
Though you wont see any new pictures from this season - apart from one shot
on 13/11/98 and a few at Moree on 30/1/99 there have been no opportunities
to photograph lightning.

Bellenden Ker reports manually at the end of each month, so these
should come in about the second week of April.
(I'm trying to find out who/what is up there - presumably no-one

At the moment 7-day forecasts are being run by the media, but they
are produced by private companies beyond day 4. I haven't seen
recently updated numbers but do know that, for Melbourne at least, the
6th and 7th days of the Channel 7 forecast were doing significantly
WORSE than climatology.
The Bureau only go to 4 days at the moment, although it's not unknown
for Queensland (especially) to put an indication of general conditions
(e.g. something along the lines of 'no significant rain is expected
until the weekend at least') beyond that in its extended outlook if
they're feeling confident. They will be going to 5 days in May with
an indication of 'general conditions' for days 6 and 7 - I've yet to
see what form this will take - hopefully it will be along the lines
of the US 6-10 day outlook (which predicts above/below temperatures/
precip for the period, rather than trying to indicate specifics for
each day), as this approach is a fair reflection of the uncertainties
involved.
(As a sidetrack, the reason that it's not happening till May is that
the Bureau is apparently required to give 3 months' notice of any
new services as part of the settlement when it got taken to court
by the NZ Met Service, who complained that the Bureau's providing of
services for free cut them out of the market...).
Having said that I don't think too much of 7th day forecasts, Sunday
does look as if it has the potential to be VERY interesting in
Victoria on both the GASP and ECMWF models.

tower on the summit) - i Think thats what I heard.
But I have driven past & flown over Bellenden Kerr and its a fairly
impressive mountain.
Also I wonder what rainfall obs could be obtained from the Mt Hinchinbrook
range NE of Townsville (pitty theres no aws there!)

G'day All
Quite a big wet season up there, though 300mm in a day doesn't quite compare
with over 1000mm/day possibly during TC Rona!
RENEWAL OF FLOOD WARNING FOR COASTAL RIVERS and STREAMS BETWEEN TULLY AND
COOKTOWN
Issued at 10:07am on Monday the 15th of March 1999 by the Bureau of
Meteorology, Brisbane.
Further heavy rainfall has been recorded in the coastal rivers and streams
between Tully and Cooktown in the 24 hours to 9am Monday. Highest totals
have
been concentrated in the area from Cairns to Innisfail and include Topaz
307mm,
Babinda 309mm and Copperlode 169mm.
Some rises have been recorded in the Johnstone River but, at this stage,
river
levels are expected to remain below minor flood levels.
A flood warning is current for the Barron and Tully Rivers.
Elsewhere along the coast, river rises are expected to cause local flooding
in
the area and motorists are advised not to enter flooded road crossings.
Isolated thunderstorms this afternoon may develop into more general rain
systems
tonight and cause further moderate to heavy rainfall.

Hi Jimmy,
I can't resist getting you excited but the models have a repeat of last
weekends forecast for the coming weekend. The NSW ASWA meeting could be
interesting if things start to fire !

I saw these and the Gosford one from Wollongong, they looked great, but
there was very little upper winds and I have learnt that this often produces
storms whose bark is worst than their bite.

Can't wait for the photos, you most probably did witness a microburst, these
events are far more common than once realised, yesterdays heat and
relatively low humidity ( it was here anyway ) in the lower atmosphere would
have enhanced microburst activity.
I am glad somebody chased to the Hunter, had I another car I would have gone
too.

Hi All,
Firstly I'm sorry if you get another message similar to this one but None of
my emails from Rocketmail (and Hotmail) seem to be being sent. I sent one
last night but it still hasn't showed up. Oh well just have to write it
again.
After alot of Umming and Erring, I finally decided that it was worth
traveling to the Upper Hunter (Sunday) just to get a glimpse of some
storms. I left St Ives around 12pm and arrived into Singleton just before
2pm. On the way up the was some very nice towers going up to the W of
Singleton. Looked a bit weak at first but seemed to be gaining in strength.
(There was also a nice tower going up near Coffs). I arrived into Singleton
to see what looked like 3 Separate cells all bunched up together W and NW
of there. I encountered the first one 5ks W of Singleton. Certainly looked
great up high with even Anvil but was a bit weak below. Only Heavy rain for
10 Minutes. Not much lightning. But I wasn't complaining it was the first
one I've been in for a while!. The other two cells were towards the NW and
were looking alot stronger. I headed over to Aberdeen which looked to be in
the path of them. On the way I did stop in Muswellbrook and took some great
shots of the two cells and an extremely dark and defined rain curtain.
Correct me if I'm wrong but there also seemed to be some microburst action
from the side of the curtain, pushing the base of it hundreds of metres
horizontally. Some more great shots!
I arrived into Aberdeen at around 3pm and was promptly hit by the first of
the two with still not much lightning and wind but extremely heavy rain and
pea size Hail. The downpour lasted about 15 - 20 minutes and covered most of
the streets and parks underwater. Got some good shots of the flash flooding
with one of the local bowls club who had no greens to play on , just
Water!!!!
At around 3:30pm headed North to the Southern outskirts of Scone to witness
the second of the two cells pass through. This one was alot more organized
with another dark heavy rain curtain (Horizontally shooting out at the
bottom again), shelf cloud (a bit unorganized at first), nice tinges of
green and some great CG lightning. This one hit with a bit more of an
impact. There was a very bright Flash and then spontaneously bang (couldnt
see where) and then a huge gust of wind and very heavy driving rain (some
hail was also observed) The wind was strong enough to break some small
branches off some trees. This lasted 15 minutes until the Hail hit, some
good size around 2cm's. This system passed onto the Barringotn area which is
pretty unpassable. So I had to be content with going back to Singleton. I
headed home down the F3 at 6pm and witnessed some great pulse storms that
shot up in a line running N - S. They looked fantastic with a clean strong
structure and circular anvil but not much in the way of lightning. A couple
of CG's near Wyong and some heavy rain but that was it. Took some more shots
at Sunset. The cloud colour was spectacular red's, pinks, and oranges! Got
home at 8pm
My only down point was that I had ripped the film out of its canister
thinking that it was a 36exp (Manual Camera) but really it was a 24exp. I'm
not too sure how many shots I have lost but Well see when they're developed.
Aggggggghhhhhhhhh!!!!!

The rainlist has come out for Berry which received 51mm on Saturday. The
rainfall in Kangaroo Valley was probably higher, perhaps by 25-50%. The band
was very narrow with both Nowra and Kiama scoring less than 10mm.
The Berry - Kangaroo Valley storm after it moved to sea produced very
extensive outflow winds from the SE, I was convinced it was outflow at
Gerroa, but when I got to Kiama it was still SE and I started to wonder, at
Shellharbour it was still SE and I was debating a SE change rather than
outflow, but the winds reversed to NW later, so it was outflow afterall.
A couple of Kiama workfriends reported hail, one indicated about the size of
2 dollar coins.
I watched the video last night and the storm whilst in the active growth
stage just west of Kangaroo Valley looked very suspicious, you could almost
imagine a rotating updraft, but the jury is out. Hope that the photos come
out.

Hi all,
I saw a very nice looking t'storm to my S today, only to find in shock
it was over 200km away! Initially it only looked weak, but while
sitting on the bus on a jammed up freeway (aren't freeway's meant to
have free-flowing traffic as the name implies? They seem more like
carparks half the time...) when I saw a very large, and prominent
'explosive like' overshoot from a fairly hard anvil. However, it was
only from this angle that it looked strong, other times it looked
relatively weak.
It had a maximum peak of 159 strong lightning strikes in 5mins...but is
dying very quickly to only 3 in the last 5mins at the moment. It
doesn't look that crash hot on the sat pic, which surprised me, as I
would have thought it was fairly high. It's moving slowly N/NNE
(towards us) but most of them die as they come off the ranges, but we
may see some lightning tonight if we're lucky. (Actually, if you have a
good advantage point to the S you should probably be able to
see some)
It's these types of days that keep me curious about NE NSW and SE QLD
t'storms...often scattered t'storms form in these areas from November to
Feb/March...but very few are documented (80-90% +) I'm certainly
looking forward to my 3 months off (Dec-Feb) next year when I should
hopefully have a car!!
