Tropical Update

Quiet weather dominates Eastern Asia while the Inter-Tropical Convergence Zone is bringing widespread showers across parts of Borneo and Mindanao. A weak LOW is also bringing a mix of rain and snow for parts of Honshu.

A developing low pressure is currently south of Japan and is quickly moving eastward. This system is bringing scattered rain showers for Southeastern Honshu, including Tokyo. Areas facing the Sea of Japan could get light snow while accumulations of 10-20cm could fall in Northern Honshu over the next 3 days. There is also a chance for a mix of rain and snow for the Tokyo Area later tonight. Quiet weather for China and the Korean Peninsula. Next chance of precipitation will be this Wednesday. Temperatures will remain very cold for the region with some slight warming by the middle of this week.

Meanwhile, the ITCZ continues to bring scattered to widespread rain showers across SE Asia. While we haven't seen any reports of heavy rains yet, we'll continue to see precipitation for the next 2 days, particularly around Borneo and Southern Mindanao. As this batch of showers move westward, chances of precipitation will increase for Malay Peninsula and even Southern Vietnam tomorrow. Rainfall amounts should range between 40 to 80mm.


Forecast Graphic, NOT OFFICIAL!

Another quiet day for the region with the high pressure to the north bringing clear conditions and cool northeasterly winds. Breezy conditions along the waters of Eastern Luzon could produce some rough surf. No large rain maker in the forecast although there could be some light rain showers by Thursday as a cold front moves on by, especially around the Bicol Region. Temperatures will remain warm with a slight cooling by Wednesday and Thursday.


Rains from the ITCZ aren't affecting the region as of the moment although clouds are spilling into parts of Visayas. Clear weather expected for tomorrow as well. Computer models are showing some precipitation to affect the region late Wednesday into Thursday so we've increased the chances to 40% around Cebu. Higher chances for Eastern Visayas. Temperatures will range between mid 20s to low 30s.


As we have forecasted 3-days ago, scattered showers are affecting parts of Southern Mindanao. While amounts are mostly light, expect rains to linger for the next 2 days. Majority of the rains are confined south of the island although we are still seeing clouds and precip moving north. Another wave can be seen near Palau which could affect the region later tomorrow. Rains are forecast to subside by Wednesday although another round of showers is forecast to return by Thursday. We are not expecting large rainfall amounts although continuous precipitation can still trigger minor flooding and landslides.

We'll have another update by Thursday (January 26, 2012)
