Summer storms to hit upper Thailand again on March 11-13, says TMD

MONDAY, MARCH 09, 2026

TMD issues its first warning for March 11-13 as summer storms return to upper Thailand, bringing heavy rain, strong winds and hail.

The Thai Meteorological Department (TMD) on Monday (March 9) issued Weather Advisory No. 1 (15/2026) on summer storms over upper Thailand, with impacts expected during March 11-13.

According to the announcement, summer storms are expected to affect upper Thailand during March 11-13, beginning in the North. The Central region, the western part of the Northeast, the East, as well as Bangkok and its surrounding areas, will be affected in the following stage.

The storms are expected to bring thunderstorms, strong winds, hail and heavy rain in some areas, as well as isolated lightning strikes.

The conditions are being driven initially by a westerly trough moving in from Myanmar over the North, while another moderate high-pressure system, or cold air mass, from China is extending across the Northeast, the East and the South China Sea, as upper Thailand remains hot.

 

The TMD has advised people in the affected areas to beware of the dangers posed by summer storms by avoiding open spaces, large trees, unstable structures and unsecured billboards. 

Farmers are advised to reinforce fruit trees and prepare measures to prevent possible damage to agricultural produce and livestock, while the public is also urged to take care of their health during the changing weather conditions.

The department also urged the public to follow further announcements from the TMD. Updates are available on the department’s website and via its 24-hour hotlines at 0-2399-4012-13 and 1182.

The next announcement will be issued on March 10 at 11am.
