The Thai Meteorological Department forecasts rain with heavy downpours in the East and South today (22 Oct), with rain covering about 60% of those areas, and flash floods and mountain runoff possible in the south. Bangkok and its vicinity see rain over about 40% of the area, with strong gusts in places. Sea waves exceed 2 metres where storms occur, so boat operators should avoid those zones. For small businesses, this means delaying outdoor work or deliveries in affected provinces and checking stock stored in low-lying areas.
