The Meteorological Department forecasts scattered thunderstorms on 1 Oct across the north, northeast, central, east and Bangkok (about 20-30% of areas), and 40-60% of the southern areas. Seas are 1-2 m in the Andaman Sea and the Gulf, with higher waves where storms occur. For a business, plan for brief downpours and possible delivery or outdoor-work delays, and warn boat or fishing operators to avoid storm areas.
