WA Pos Tropical low watch Dec 12- 19 2010
« on: 12 December 2010, 05:47:42 PM »
Hello all it looks like there could possibly be a Tropical low developing mid next week in the Indian ocean and may make contact with the WA Coast on Friday December the 17th 2010

BOM outlook no 1 :

Potential Cyclones:
There are no significant lows in the region at the moment. However, a monsoon
trough is expected to strengthen over the region during the weekend and a
tropical low is likely to develop south of Java by early next week.

Likelihood of a tropical cyclone being in the the Western Region:
Sunday      :Very Low
Monday      :Low
Tuesday     :Low

Weatherzone Charts :



BSCH wind Chart Start Monday End Saturday each day is 9am



So it will be interesting to see what happens here so sorry if i have posted a little early but i am just looking forward to monitoring this possible event.

The latest update for the western sector is there is the potential for 1 cyclone and another low forming over the next few days.

BoM :

Potential Cyclones:
At midday WST a weak low was near 13S102E, around 450 kilometres south west of
Christmas Island, embedded in a monsoon trough. It is possible that the low will
develop into a tropical cyclone by late Tuesday, or more likely on Wednesday or
Thursday, by which time it is expected to be moving towards the south southeast.
       
   
Likelihood of this system being a tropical cyclone in the Western Region:
Tuesday     :Moderate
Wednesday   :High
Thursday    :High

Another tropical low may develop off the Kimberley coast on Thursday.

Likelihood of this system being a tropical cyclone in the Western Region:
Tuesday   :Very Low
Wednesday :Very Low
Thursday  :Low

Just looking at the current sat pics and obs for the western region and it appears that one of the lows embedded in that trough must be very close to forming into a tropical low. It would not surprise me to see some time later today BoM showing a TL on the track map.
It is an interesting sat image from Western Australia right over the NT and the Cape in QLD.

A topical low did form yesterday at 20S110E just of WA.


BoM

Potential Cyclones:
At midday WST a tropical low was located near 20S 110E, about 480 kilometres
west northwest of Exmouth, within an active monsoon trough. Gales are possible
to the north and south of the monsoon trough, please refer to the latest
Shipping Warnings for more details [IDW21100, IDW21200]. The low may develop
into a tropical cyclone during the next 3 days, although it is more likely to
remain a large monsoonal low with strong to gale force winds well away from the
centre.

Well not a TC but it did smash some rainfall records in the Gascoyne region of WA. This was posted elsewhere by Don White:

Records are detailed at http://www.australianweathernews.com/news/2010/101217.SHTML. Carnarvon AP's total of 204.8 for the 24 hours to 9 this morning was almost exactly double its previous all time one-day record in 65 years (102.6mm, 13/7/1998). Marron with a 99 year history also set a new all-time record by a considerable margin (166.4 compared to 132.4 9/3/200).

Quite an incredible rain period!  200mm in reflection of what, 1.8mm for the average!  The only part of Australia that desperately needs this rain is Perth..their dam level is a miserable 35% whilst the rest of the country's dams are overflowing.

I'm currently in Perth on a work trip and the rainfall / flooding up there has been receiving a bit of coverage on the local news. They have been commenting about the areas getting it's annual rainfall in 24-48 hours, and some extensive flooding shown with buildings east of Carnarvon underwater.

Here in Perth we may get some showers from it tomorrow as it tracks south and weakens.
