The Meteorological Department says heavy rain will continue in some areas, with very heavy rain in the east (Chanthaburi, Trat). Bangkok and vicinity have thunderstorms over about 60% of the area. Warnings: flash floods and landslides near streams and low ground, and the Andaman coast has waves of 2-3 m or more, so small boats should stay in port. If your shop, warehouse or delivery routes are in the east or the north, plan for delays and water risk, and check stock and deliveries in low-lying spots.
