Spring Storms From Hong Kong to Japan, Damaging Winds and Heavy Rain Warnings in Place

The roller coaster ride of spring weather continues to bring its ups and downs across north east Asia this April, and this week is no exception to that.


On Wednesday a storm system can be seen tracking north east across Japan and South Korea where it is expected to bring strong to severe storms at times and at the very least a wet day for those commuting Thursday morning.


Already this storm has been impacting South East China, in Hong Kong high wind warnings were issued for gust up to 100kph Wednesday morning due to strong thunderstorms.  Wide spread rain alerts have also been issued. Check more on these warnings here.




In Okinawa Severe Thunderstorm warnings have been issued for lightning, damaging wind gust and the possibility of tornadoes through Wednesday afternoon.

Furthermore up to 150mm of rainfall is expected across the Southern Japanese islands Wednesday.

Watch the radar for Okinawa at this link. 

Wednesday night in to Thursday the storm will track north east passing along the Pacific coastline of Japan bringing the threat of flash floods in the mountains of Shikoku and Tokai. Thunderstorms are still possible but should be less violent as the ones further to the south on Wednesday.

The Thursday morning commute in Tokyo and Nagoya will be a wet one too. Those rainy season boots you are storing for May and June might need to be broken out a little early. Good news is that by the afternoon hours this hard charging system should have moved east so by the time work is done conditions should have improved and sunny skies will be moving in heading in to the weekend.


The next storm system to impact Japan will be on Sunday, big thing with this the Jet stream will be further north allowing more tropical air to infiltrate the region pushing temperatures to some of the warmest yet this spring.


Daily update- Tuesday, April 12, 2016

NWPAC outlook, 12 APR

NWPAC outlook, 12 APR

Unsettled weather begins to show up in the north region, as showers and thunderstorms affect much of the central region. More dangerous heat is on tap for the south region, while the tropics flat line. 


A frontal system extending to the southwest from eastern Russia and through northern China will be the focus of clouds and a few showers today. Temperatures behind the front are negligibly cooler, and the air mass is still a bit moist as new moisture comes into the picture from the west. Remnant moisture associated with the last storm system will couple with this incoming moisture as another weak pulse of low pressure spins up over north-central China during the next 24 hours. Clouds and showers will be prevalent across the eastern seaboard of mainland Asia today, as Japan sees the most sunshine of all locations in the region.

City High Temp C (F) Low Temp C (F) Conditions
Ulaanbaatar 11 (52) -5 (23) Scattered Showers
Vladivostok 7 (45) -1 (30) Rain
Beijing 20 (68) 7 (45) Partly Cloudy
Seoul 22 (72) 12 (54) Cloudy
Tokyo 14 (57) 11 (52) Fair
Xi’an 26 (79) 9 (48) Partly Cloudy
Shanghai 19 (66) 14 (57) Rain



Unsettled weather remains fixed across the central region as moisture along a stationary frontal boundary in southeastern China. The frontal system will be a focal point for showers and a few thunderstorms during the peak of afternoon heating today. Many locations will see good weather today, especially to the west and south, with just a few scattered clouds.

Kunming 26 (79) 13 (55) Partly Cloudy
Hong Kong 24 (75) 23 (73) Thunderstorms
Taipei 26 (79) 21 (70) Partly Cloudy
Iwo To 24 (75) 21 (70) Scattered T-Storms
Hanoi 31 (88) 22 (72) Partly Cloudy



Intense and dangerous heat is once again in place across a good portion of the south region today. Once again, words escape me when trying to point out the risks of heat exposure in portions of Cambodia, Laos, and interior locations of Thailand and Vietnam. Longer days, intense sunshine, and ample humidity, will combine to drive up heat indices, which could approach 48C (118F) in some areas. Residents of these areas should avoid prolonged afternoon exposure to the conditions, and restrict any vigorous activity to the early morning and late evening hours. The northern Philippines will also see intense heat and humidity today, with heat indices of 41C (106F) possible, especially over inland provinces of Luzon. Extreme caution should be observed if plans take you outside this afternoon. To the south, plentiful tropical moisture will offer up a chance of thunderstorms to the southern Philippines, Singapore, Malaysia, and Indonesia.

City High Temp C (F) Low Temp C (F) Conditions
Siem Reap 41 (106) 26 (79) Fair
Ho Chi Minh 35 (95) 27 (81) Partly Cloudy
Manila 36 (97) 26 (79) Partly Cloudy
Davao City 33 (91) 25 (77) Scattered T-Storms
Brunei 32 (90) 26 (79) Partly Cloudy
Singapore 33 (91) 27 (81) Thunderstorms



The tropics remain quiet today, and as a matter of fact, convergent activity as observed VIA satellite has significantly diminished over the past 3 days. The heat and moisture continues to build up in the region, making for some very warm afternoons. However, without any concentrated areas of convection, activity is scarce. A good chance for showers and thunderstorms is in place for the islands of western Micronesia, while most other locations will see plenty of warm sunshine.
