03 FEB 2012 Eastern Asia / Western Pacific Weather Update

Cold and wet weather continues across Eastern Asia today as a deep area of low pressure spins to the North East of Japan. In the wake of this low cold air is rushing across the SOJ producing record breaking snowfall along the Western Coast of Honshu Japan. This snowfall will likely take a break on Sunday as an area high pressure settles over the country. Temperatures as low as -30C is expected in much of North West China and Mongolia. Across Korea and Eastern China the area of high pressure is bringing dry and stable weather but bitter cold temperatures. Moving in to early next week a new low will developing bringing another shot of wet weather to Eastern Asia The image to the right shows the model outlook for Sunday with an area of rainfall extending from Japan through Taiwan extending across Eastern Asia.

The tropics remain quite today in the Northern Hemisphere as the North East monsoon continues to remain weak. Scattered afternoon thunderstorms are still expected but no tropical activity is foreseen on any of the model outlooks in the near future.

Cyclone Iggy / Tropical Update 02 FEB 2012

Today’s Update is from Our Partners at OZCYLCONECHASERS.COM

MAIN POINTS

(1) Ex Iggy to hit the WA coastline between midnight and 6AM tomorrow WST. Most of the heavy rain and stronger winds will occur prior to landfall as the system weakens on approach to the coastline. Most of the strongest winds will be to the SW of the system’s centre and the heaviest rains will be to the south of it.

(2) Coral Sea LOW located over the Peninsula right now and will move quickly to be east of Cairns by 4AM tomorrow morning. The LOW should then slow for a few hours while it develops and then resume a fast push to the east or east south east and possibly develop into a marginal TC on saturday morning or overnight Friday. There is still a lot of doubt as to whether this system will even attain TC status, but the slightly favoured scenario is for it to become a Cat 1 TC.

(3) Heavy rainfall should occur as the LOW pushes offshore over Nth and FNth Qld after 10AM tomorrow as an inland trough and the easterly feeder bands combine to enhance convergence into the LOW.

(4) The LOW will have an unfavourable interaction with a Fijian system that may temporarily weaken it to below TC intensity between 155E and 160E should it have achieved TC intensity in the first place.

(5) Longer term (after the current LOW) no cyclone development is expected anywhere in the Australian region until at least mid February.
