Meteorological Department Issues Warning: Severe Thunderstorms to Batter Thailand April 29-May 1, Lists High and Moderate Risk Provinces

The Thai Meteorological Department issued its first severe thunderstorm warning (41/2569) on April 27, 2025, affecting northern Thailand from April 29-May 1. Thunderstorms with strong gusty winds, hail, heavy rainfall in some areas, and possible lightning strikes are expected to begin in the North, Northeast, and East regions before moving to central Thailand, Bangkok, and surrounding areas. A high-pressure system and cold air mass from China will interact with hot conditions in northern Thailand, creating favorable storm conditions.

Residents are urged to avoid open areas, large trees, unstable structures, and weak signs. Farmers should reinforce fruit trees and prepare measures to protect crops, livestock, and agricultural operations. Residents should monitor updates from the Meteorological Department via their website (http://www.tmd.go.th) or phone lines 0-2399-4012-13 and 1182, available 24 hours. The next warning will be issued on April 28 at 5:00 AM.
