The Thai Meteorological Department warns of thunderstorms, strong gusts and heavy rain in the north and northeast today (4 Oct), spreading to central Thailand, Bangkok and the east. Rain is forecast to increase again 8-13 Oct, with heavy to very heavy falls in some areas of the east, central region, Bangkok and the south, raising the risk of flash floods and flooding. For businesses: secure outdoor stock and equipment, plan deliveries and staff travel around the 8-13 Oct window, and check flood-prone premises. Sea waves above 2 m are expected in areas with storms, so boat operators should take care.
