Hi all,

I thought that I'd forward this email to the list as some people might
be interested in it.  It's a new plotting programme, so that you can
choose an area (ie rectangle, rather than a square, and you don't have
to worry about lat/longs).  Only one catch - the only way to get
Australia the right side up in your final plot is to just click on the
map, but you only get a square image again, and you have to fiddle with
how many degrees radius you want.  I've emailed and requested that they
can devise a way to fix this, and have Australia the right side up.

------------------------
We have added another method to choice a map domain when plotting
meteorological fields with the Interactive Forecast Mapping program
(ARLPLOT) in READY.  You can now use a rubber-banding technique to
highlight the rectangle of interest.  This will only work on the
newer browsers that support java-based programs (the original method
is still available for those that don't have a recent browser). As
this is new and experimental, please submit problems to the READY
webmaster.  Enjoy!

Hi all,

On Wednesday, the radio apparently interviewed some one who witnessed
the phenomenal severe electrical t'storm that hit Texas, and several
other towns at around 2:30am Wednesday morning.  This person said
"...there were balls of lightning rolling across the ground!  I have
never seen this before in my life..."

Tracker was reporting phenomenal amounts of lightning, in excess of
100CG's per minute.  As Ben mentioned earlier, there were also reports
of people losing their roofs.

Anyone care to comment?

A potentially very nasty tropical cyclone is currently churning away
in the Bay of Bengal. It has sustained winds of 135 knots at present,
making it a Category 4 storm. It is forecast to intensify further.
Given that most Bay of Bengal storms don't get beyond Category 3,
this is a fairly serious matter.

The forecast landfall point is in just about the worst imaginable
place - near the border of India and Bangladesh, putting the 
Bangladesh coast in the firing line from any storm surge.

Given the past history with cyclones in this area, the death toll has
a fair chance of being catastrophic. Anyone want to guess what body
count will be required for the story to make it onto page 1 of an
Australian paper? (There have been six-figure tolls from cyclones on
two occasions in the last 30 years in this region).

Probably over 1,000,000 before they will touch it.

NOt a bad TC considering that they are at the end of the season - wonder if
thats a prelude for our TC season?

Certainly this will be a complete disaster - the TC that hit Bangledesh
in 1970 killed between 300,000 and 500,000 people.  The main killer was
the storm surge, much of the area isn't much higher than sea level.  The
figures I have on this TC was only a Cat 2 (160km/h gusts)...although if
some one believes they have more reliable, conflicting figures, I'd be
more than happy to accept them (as this sounds too weak to be
believable...)

Anthony -
They said last night on CNN & BBC news that it was a Cat 4 TC  with winds at
arounf 130 knots - normally I wouldnt believe the news but they both agreed so
they must be getting their info from somewhere.

Paul.

Hi All,

I apologize for the lateness of this email. I have been having lots of
problems with my email and it is only now that I have been able to post this

SATURDAY 23 OCT

Well last weekend was a very interesting weekend with the rain really
starting to come down on Saturday morning in Sydney and the Low developing 
to the north things were looking good for NW of Sydney.
After a quick check of the LI's and of the latest Sat pic of NSW it was 
decided that the best place to head would be Dubbo. I set off and picked up 
Jimmy on the way and were out of Sydney by 9am. We drove across the 
mountains into Lithgow through steady rain, but as we came to Orange the 
rain lightened up and revealed a nice looking band of rain and embedded 
storms. What was interesting was that it was only 11:30am at this stage. 
Nothing worth chasing as we though. The road from Orange heads N to Dubbo 
and the whole way up we drove through constant heavy rain with the 
occasional strike of lightning nearby. A quick phone call from Patrick and 
Michael Bath assured us that we were not far from the end of the band. And 
sure enough as we entered Dubbo at around 1pm we could see the clearing to 
our N to NW.
We headed N from Dubbo towards Gilgandra and stopped about half way right 
underneath the clearing. What a sight it was, perfect conditions also. There 
were storms to the N, NE, E the rain storm band to SE and S with more 
developing stuff to our W with some great accas to be seen in the clearing.

Another Phone call advised us that the storm to our NE was a Severe storm . 
It certainly looked good with a nice boiling updraught coming from behind 
but it looked a bit too far to go after and considering the speed they were 
traveling it was decided it was not worth it and we would wait for the 
action to the clearing in the W to develop. We also noted the inflow from SE 
to NW of the developing storms to our NW. The visible low cloud was really 
being pulled into the new system and the wind on ground level was extremely 
strong.

We ducked into Gilgandra and picked up some lunch before heading onto the 
road W to Warren. We stopped about 10 kms out of Gilgandra and watched as 
the cloud cover had formed above and to our N to E a band of embedded storms 
were once again teasing us to go after them. But still we stood our ground 
and waited for the new development (now above and to the W) to do something. 
There was now 100% cloud above us which is a pity as we couldn't see any 
vertical development. By about 3pm heavy rain dropped from the sky to the S, 
above us and to the N. Nothing too exciting though. What took our attention 
though was the sky to the W. It had taken on a very dark appearance and so 
was decided we would head further W and see what we could make of it. About 
10kms further we pulled over to get some shots of a now active storm to the 
W.  It had a very nice green tinge with what seemed to
be a mixture of hail shafts and heavy rain underneath. There was however not 
too much lightning to be seen.  The cell passed and all that was witnessed 
was one very close CG and some very heavy rain. Once passed there wasn't too 
much further W at that stage just a lot of cloud cover. We headed back 
towards the storm and Dubbo but couldn't catch it. Some very nice Mammatus 
be seen from the back end. At 5pm we started back the journey to Sydney 
.There was more developing Congestus turning to Cb to our west again, but it 
looked very weak. Arrived back into Sydney about 10pm after traveling 900kms
for the day. It was definitely worth the trip and I know it  gave me a great 
incite on how Low pressure systems affect the weather across the state.

SUNDAY 24 OCT

9am -  Once again a quick check of the LI's, winds  and satellite and once 
again I was off to Williamtown to meet up with Jimmy. There certainly was a 
chance for some strong storms especially with the shear and the strong upper 
level winds near the Hunter and Northwards.
On my way out I stopped at a lookout at the end of my street with a clear 
view over the City and Southwards.  Well I can see why Wollongong copped a 
hammering. There was clear sky all around but to the South a wall of CB's .A 
very pretty sight. I even had people walking past commenting on how amazing 
it looked, and I m happy to say that I got some great shots and video of it.

By now it was around 10am , crap I was going to be late meeting Jimmy, but 
it was worth it.Headed straight up the F3 and in no time at all was past 
Newcastle. A quick call from Jimmy alerted me that there was already some 
severe storms to our north near Taree and onwards. Bulahdelah was our new 
target area. At Newcastle I ran into a decaying cell that was just dumping 
alot of rain.I meet Jimmy near Buladelah at around 12:30pm and received a 
call from Max who advised that  the more intense cells had passed out across 
the sea and were moving again at high speeds. There was one in particular 
near Taree
that had been showing Red for a while. Apparently there was more development 
to the N and NW of Taree all heading SE which at this stage was covered by 
low cloud.

After a quick bite it was back on to the Pacific HWY towards Taree. On the 
Bulladelah range we encountered a nice cell with some very heavy rain which 
made the trip across quite interesting. On the other side we broke clear of 
that cell and could see to our north through the broken middle level and low 
level cloud some very nice anvils.Near Nabiac at around 1 - 2pm we picked up 
some petrol and was advised by the garage owner that Taree had reported up 
to golf ball size hail in places from the Big cell that went through about 
12pm. A quick look out the window showed a very dark base heading towards 
us. Unfortunately the low level cloud flowing into the cell was covering all 
the features of it. A quick look again and it was decided to head N of the 
cell hopefully to get a better view of it and to get out of the way off the 
Hail. We ended up at Old Bar about 15km E of Taree and watched as the main 
cell passed to our South. Some weaker cells with just heavy rain passed over 
head but the annoying part was that the Lowcloud didn't clear so no 
significant features could be seen, not even the back of the storm. Some 
more calls from Max and Anthony gave us the news that the main stuff had 
passed out to sea but there was stillmore developing to the W and SW.

It was now about 3pm and not wanting to be too far from home headed back to 
Williamtown. We got there about 4:30pm and witnessed something that I have 
never seen before. On the whole coastal fringe N and S was a mid- high level 
Stratus type cloud. To
the W and NW was just blue sky, but very dry looking. Right on the edge of 
the stratus cloud was a large congestus that had grown right through the 
cloud layer. Just that looked great but what really made it special was the 
fact that from side on we could see the whole formation of it very clearly. 
This cloud also seemed to be rotating  clockwise as it rose!!!! it sure was 
a great example of the rotational shear that day it. It was just south of 
Newcastle crossing the coast , no chance of going after it but a very nice 
sight.



Back on the F3 again and heading to Sydney at about 6pm and another surprise 
for us. Another Cell coming across from the W. With the Sun setting in the 
background it sure made for some nice photo opportunities. At wyong we 
passed to the side of it and was surprised again as hail started pounding 
against the roof of the car. A quick stop at the Servo (protection for the 
car) and some nice CC's and we were on our way home again. Another 
interesting day chasing. It was great being able to get out and witness 
these events first hand. A big thanks goes out to Anthony, Max, Michael, 
Patrick and others who called with regular updates.

What a season so far ......... and its only October

The Weather Channel's web site (www.weather.com) also backs this up.

This article also quotes possible storm surges of 6-12 metres. I
gather Bangladesh has a better emergency response system than they 
did in 1970 (when there was also a lot of political unrest), but
evacuating everyone on the coast to higher ground, which is what the
Americans would be doing in a similar situation, is presumably still
beyond them.

WX & ASWA-people,

I've just lost contact with http://www.npmoc.navy.mil/ from 13:30
today which is returning the error "client forbidden". Can this
be confirmed or otherwise by other persons on the list or in ASWA
ASAP please? I'm trying to isolate the problem.

Please note that if access is not restored from my computer, then
the hourly archive of gmsd/gmsc/gmsfull will cease and you will
need to obtain archive satpic images from elsewhere

Just checked out the latest warnings (via the Hong Kong Weather
Underground) on this storm. The good news is that it isn't heading
for Bangladesh. The bad news is that it has intensified further and
now has sustained winds of 140 knots.

It is currently about 300km SSW of Calcutta and is expected to make
landfall by 0600Z (1600 AEST) about 60km NE of Cuttack (a city of
some size which I know of chiefly because Australia's played the
odd cricket game there). I don't know much about how heavily populated
this coastline is (although presumably there's no such thing as
sparsely populated coastline in India). Still, it sounds like a less
horrific scenario than it could have been (although I'd still expect
the death toll to be in the hundreds or thousands).

The CIMSS satpic cloud motion data is useful here, showing the average
windsheer between the 925/700hPa layer and the 350/150hPa layer every
6 hours. They have also just introduced (yesterday) panels showing the
24-hour windsheer change. URL is

Hi Michael,

This is my first post here, so hi! everybody....

I can confirm that there is some trouble with http://www.npmoc.navy.mil -
I get the same error message. 

All the information is stillavailable at the NRL Monterey California:

kauai.nrlmry.navy.mil:80/sat-bin/tc_home

At 00Z the cyclone was more or less on the coast not far from Cuttack and
had started to weaken rapidly. There is still good organisation there, but
the cloud tops have warmed considerably, and the eye was becoming ragged.
Definitely not a worse case scenario for Bangladesh, but not good either.
There has been strong on-shore winds up the entire Bay of Bengal striking
the Ganges delta - there will be a substantial storm surge there, even
though the cyclone did not hit directly. The forecast recurvature has been
delayed, and that has partially saved Bangladesh. But recurvature is still
likely, which will take the remains of the storm over Bangladesh. There's
going to be a lot of water hanging around there with not many places to
go. 

A death toll in the thousands would seem likely all things considered, but
anything above 10 000 would be slightly surprising IMO (depening on the
immediate future of the TC of course). 

Jonty.

Hi all - made it safely to Darwin - bloody hot although it is raining as we 
speak. Storm already which is a good start. Cells galore atm - only clear 
area really is the NW. Hector is going and is its usual 18-20km or so in 
height. Cells from E round to the W. Off to have a look now and run around 
in the rain to cool off a bit :)

May everyone get good storms

I can get on to http://www.npmoc.navy.mil/ and
http://www.npmoc.navy.mil/products/jtwc/GMSFull_ir2.jpg ok (at
15.50EST). The full ir2 is a bit strange, with the top 10% normal and
the bottom 90% reversed and purplish. Maybe they're having problems.
