The Meteorological Department forecasts heavy rain in parts of the North and Northeast, with about 60% of Bangkok and surrounds expected to get thunderstorms today. Rain is due to increase from 8–13 September, starting in the Northeast. For SMEs: plan deliveries and outdoor work around flood-prone low ground, and check stock stored at ground level. Sea waves are about 2 m in the Andaman Sea and Gulf of Thailand, so boat operators should take care and avoid storm areas.
