Tropical Update

Mostly quiet for our forecast area today and hopefully should stay quiet for the next few days. A batch of rain showers from a frontal boundary are affecting parts of Southern Japan. Also some scattered thunderstorms over Wake Island with the upper-level low. Lastly, we have isolated thunderstorms popping up across the Tropics.

We begin in Eastern Asia where a slow-moving front is causing some showers across parts of Kyushu, Shikoku, and Southern Honshu. Most rainfall amounts in the area have ranged from 40 to 60mm, Rain should be ending here tonight. The rest of Eastern Asia looks quiet right now although another bath of rain showers could move in towards Central and Eastern China by this weekend. With that, temperatures will cool down, especially for Korea and Northern Japan where temperatures could fall into the single digits again.

Tropics are mostly quiet right now with dry air and subsidence influencing the clear weather. As is usually the case, there will still be some isolated thunderstorms forming, especially in the afternoon. These rains could drop a quick 30 or even 50mm of rain in less than 3 hours which could definitely cause minor flooding and flashfloods.


Forecast graphic NOT OFFICIAL!

Not much to write about in terms of the weather forecast. Mostly dry conditions will continue prevailing for the next 3 days or so. Highest chances of seeing widespread rain would be in Northern Luzon this weekend as a weak low is forecast to move in near Taiwan. Another area to watch out for would be Southern Mindanao. The ITCZ is pretty benign right now and any showers forming will stay mainly to the south, near the equator. Still, we can't rule out a possibility of a stray shower affecting Eastern Visayas and Mindanao. Aside from that, nothing really major in the forecast. Temperatures will range from mid 20s to low 30s (mid 30s in the cities like Metro Manila).

Next update will be on Sunday, March 11.
