Tropical Update

We are watching rain affect parts of the forecast area today. In Eastern Asia, a developing front is bringing light to moderate rain across Eastern China, Southern Japan, and the entire Korean Peninsula. Further south, the ITCZ is also bringing scattered thunderstorms across Borneo and parts of the Philippines.

Latest satellite image shows the front affecting much of Eastern Asia. Places near Shanghai and provinces like Fujian, Zhejiang, and Anhui are all reporting rainfall amounts of between 50 and 80mm these past 24 hours. Northern Taiwan is also seeing some light to moderate rains. Rain in these areas should lighten up in the next 12 hours. Meanwhile, a line of thunderstorms are going to affect the Ryukyu Islands tonight bringing thunderstorms, windy conditions, and potentially heavy rainfall. It should be gone by tomorrow though and we aren't expecting any big rain amounts. As for the Korean Peninsula, widespread rains will continue until tomorrow and could bring as much as 50mm in some areas. Japan will also get rains throughout tomorrow although amounts will mainly be light (25-50mm). Northern areas such as Hokkaido, and NE China (Harbin) will get a mix of rain and snow and then changing to moderate snow. Behind this front will be cold air that will last until Wednesday. Warm-up is expected by the latter part of the week.

As for the tropics, the ITCZ continues to bring scattered thunderstorms across Borneo. Some areas here are reporting 60 to 90mm of rain these past 24 hours. More rain could be on the way though as the surge of moisture continues. Light to moderate rains have also been affecting Eastern Visayas and Mindanao since yesterday. Most rains though have been relatively short and isolated.

Mainly dry and warm. There could be some rain showers affecting the Bicol Region tomorrow although should not last too long. A front will move through Tuesday which could bring light rains across Northern Luzon. Temperatures will be warm, especially in Manila where daytime highs could get into the mid 30s.


On and off thunderstorms will continue, particularly in the eastern sections. Again, we're not expecting large amounts of rainfall although these thunderstorms can still cause flooding and landslides in some areas. Temperatures will range between mid 20s to low 30s.


Isolated thunderstorms will continue for parts of the region, especially in the eastern and southern portions of the island. Another surge of rain could come in by Wednesday and could affect a larger area and bring heavier amounts of rain. Temperatures should range between mid 20s to low 30s.

Next update will be on Thursday, March 8.
