Hi All :)
TC gwenda looks like giving Karratha some interesting weather tommorow, especially with her moving South towards Karratha.
We have Showers and Storms forcast and Winds forcast to strengthen close to Gale force during the day.
Although as she moves further south its expected to weaken from unfavourable conditions......so we will see what happens. :)

Hi Les
Unfortunately our BOM most senior staff are seeing the UK Met Office as an example to follow. New Zealand is also another ideal that our present government looks too.
Thank God for the Internet, then!! As you probably know there are a small hard core of chasers over this end but fuel costs, congested roads and no free flow of data almost does it for us...
You mentioned that you are coming here next winter, is that your winter or ours ? if yours does that mean you may be chasing over here ?
Correct. Our winter = your summer. From what I've read from aus - wx Austrailia is the place to go chase and the thought of sun, sea, sand and supercells is almost too tempting...
I often wonder with the weak Pacific Peso ( Australian Dollar ) why some US and UK chasers have not taken advantage before. Granted we do not get the intensity of tornadoes as the USA, but we get several days each Spring - Summer that have supercells.
I've had my share of FC's, CG's (more common in the UK due to the higher latitude) and tornadoes in the UK - its the supercells I'm after and being Scottish may not even get the 'whinging pom' label... :) Looks like I may be there next January all I have to do is persauade the better half...
3000 km - no problem I can do that in a coupla days over here...

Subject: aus-wx: PLEASE READ - RE: ASWA Insurance & Discussion
Sender: aussie-weather-approval at world.std.com
Reply-To: aussie-weather at world.std.com
This topic has again raised some interesting points. One thing to remember
is that Lawyers will always jump on the liability band wagon if they can
sniff money attached to it. However we need to stay focused on a few
issues:
1. Liability.
Mozley & Whiteleys Law Dictionary defines liability as "being under an
obligation". ASWA is purely a voluntary organisation and as such any person
cannot find themself under an obligation. However during a "chase" the
driver is still under an obligation to comply with their respective Traffic
Acts and to drive as a reasonable & prudent driver would do. As for
insurance for cars sure there is a grey area regarding this. If it is found
that the insuree deliberately put their car in a position of danger then
the insurance company may not pay out - however their are always ways and
means around this (such as " I was out for a drive when this monster storm
suddenly caught me........."). As for insurance with ASWA I would most
strongly convey my opinion that we do not need it : - as soon as ASWA
starts to place people under obligation we move from being a organisation
to an obligation - and I think that the voluntariness of ASWA is what makes
it most appealing - its something people do because they want to - not
cause they are told to.
With CTP (compulsory third party insurance) Im not 100% sure but I was told
that it is also legislated that these "Green slips" are supposed to cover
all injuries and death - thats why we are required to pay for them.
Remember though it only covers third parties. I would recommend any one who
uses there vehicle for a chase that they have full insurance as well for
their own safety. It may be needed that we remove the word "CHASE" from our
vocabulary and use a less negligent term i.e. one that doesn't convey a
negligence on behalf of the "storm observation."
2. Hiring of cars for chases.
THIS IS A BAD idea. Not only are you not insured (you have to pay extra for
insurance) rental companies normally have a whole list of cant do's (for
example when we were in Darwin we were not allowed on dirt roads or outside
certain areas) and if you breach them you are solely responsible for loss
or damage as well as any personal injury ( which in NSW the amount you can
sue for is unlimited in Motor Vehicle accidents).
One thing to remember is not to get caught in hype. What makes us
difference to a camera club on a nature outing or any other voluntary
organisation on an outing? Nothing. Every activity these days has an aspect
of danger. Its part of society. We need to stay focused and not panic. Be
careful when driving, make sure that every passenger understands that they
are there under there own "steam" and that no liability is accepted if
something happens (unless the person driving was behaving like a fool
etc...) When partaking in an "observation" make sure that everyone agrees
to the course of action and route. This goes along way to removing
obligation or liability.

can contribute to the success of that Mission.
2. My membership in ALERT can be canceled by myself or ALERT

Hey Ben from Brisbane here..
This URL is for UNISYS, and it has maps (using AVN data) for Australia that
no other site has on the internet (not that i know of), such as forecast
Showalter Index values, and also some other nifty stuff... I also like the
style they are in (although they are quite small). They've been around for
quite some time, but was only availbable to NEMAS members up until today -
knock yourselves out.
http://weather.unisys.com/aviation/index_aus.html
The maps are updated from about 2:30pm onwards of an afternoon, and about
2:30am overnight as well - this is MUCH better than the maps we get from
FNMOC, wich are normally not updated to 7pm at night or later.
Been off the list for about a month.. nothing hugely exciting up here,
couple of nice night storms over souther parts of SE QLD over the past few
weeks.. and 50mm over the easter period - with 25mm on top of that from a
heavy period (45mins) of rain last night.

Yes Ben,
These are one of the sites I had contacted to do this but I had also asked
them to make them a little clearer. Otherwise it is very difficult to read.
They had also promised other information.
When i last checked, I had not taken motice of the Show as an index. It is
very hard to follow at first.
But who's complaining. I hope the other site which I have linked off our
site also gets its data out. It shows a fair bit of promise but not for
Australian data
http://www.australiansevereweather.simplenet.com/links/ozcharts.htm
second link below the usual AVN data links
How frustrating for everyone here to not have this data available.

Hi all,
I don't think I have posted this URL Ben. One thing to note is that
this site is not always updated, so don't despair if it doesn't work
initially, try again later - as sometimes it can take a while for the
data to come in. Unfortunately it's poor format, which is a shame, as
IMO EC is a very good model...

Hi Anthony!
Yeah! Right!
However...that must mean that night tornadoes go unreported (or even
worse...unforecast!) Just because no-one sees them doesn't mean that
Doppler doesn't etc...I agree that most people are killed by F4/5's
but I wouldn't mind betting that the majority of tornado deaths occur
from storms in the middle of the night or early morning...
any thoughts?

I often wonder with the weak Pacific Peso ( Australian Dollar ) why some US and UK chasers have not taken advantage before. Granted we do not get the intensity of tornadoes as the USA, but we get several days each Spring - Summer that have supercells. The last being the 30th January 1999. As for severe storms it is not unusual in the Nov - Feb period for 2 out of every 3 days to have a severe storm warning out somewhere in VIC, NSW or QLD . Mind you we are talking serious kilometres to chase all these, for example from Western Victoria to say the Capricorn coast in Queensland may be 3000km.

Hi All,
Bad news for me this week. I have glandular fever. Seems like it'll be an
intersting few months coming up for me. I still managed to go storm
chasing briefly on Monday (don't tell my mum). I hope I didn't give it to
you Chris.....(sorry if I did).
Interesting to read all the info about insurance,etc.
Can't wait till we start recording more tornadoes here in the wonderful
land of OZ.
Sorry - very boring letter.
OH YEAH - Good luck to Jason who is preparing for another close shave from
another cyclone. Enjoy yourself but be safe.

Hi Jane!
Hmmnn...I agree with all five points...
First the pros...
* the chances of being seriously injured on a storm chase (just
statistically) would have to be minor...however...you can be struck by
lightning taking in the washing before a thunderstorm (is that legally
an "Act of God"?) even though you should know better?
* You can drive under overpasses at any time and have somebody throw a
rock on the car....(foreseeable risk?)
* normally if chasing a storm we take inordinate care to see where
we're going! Unlike 90% of other road users!
* to avoid litigation as regards "organisation" of chases...well, I
guess (unfortunately) we chase alone...
Now the cons...
* when dealing with lawyers (and insurance companies) there are is
just one thing to remember...
* if you ask one, "How much to ask you just two questions?" and they
say "$200...what's the other one?" Don't be surprised!

Funny you should mention about night tornadoes, there are parts of the US
Mid West were nightime thunderstorms are very common ! more so than in
Eastern Australia, and yes they have tornadoes.
You are right about the doppler and in the US this again increases the
number of tornado occurences over say Australia where we do not have
widespread access to such things.

Let the gang know before you come over, I'm sure there are a few here that may want to chase with you. Even if the storms lay low there is the sunshine, mind you in January you may get burnt to a crisp if you are not careful.

Thank God for the Internet, then!! As you probably know there are a small hard core of chasers over this end but fuel costs, congested roads and no free flow of data almost does it for us...
You mentioned that you are coming here next winter, is that your winter or ours ? if yours does that mean you may be chasing over here ?
Correct. Our winter = your summer. From what I've read from aus - wx Austrailia is the place to go chase and the thought of sun, sea, sand and supercells is almost too tempting...
I often wonder with the weak Pacific Peso ( Australian Dollar ) why some US and UK chasers have not taken advantage before. Granted we do not get the intensity of tornadoes as the USA, but we get several days each Spring - Summer that have supercells.
I've had my share of FC's, CG's (more common in the UK due to the higher latitude) and tornadoes in the UK - its the supercells I'm after and being Scottish may not even get the 'whinging pom' label... :) Looks like I may be there next January all I have to do is persauade the better half...
3000 km - no problem I can do that in a coupla days over here...
