The Meteorological Department warns of heavy to very heavy rain across the Upper Northeast and Mekong basin, with flash floods and mountain runoff possible in Ubon Ratchathani. Bangkok and vicinity have a 60% chance of rain over the next 24 hours. Sea waves in the upper Andaman Sea are above 2 metres. For a business, this means checking stock and deliveries in low-lying areas, avoiding flood-prone routes, and delaying sea trips in storm zones.
