The Meteorological Department forecasts thunderstorms and heavy rain in parts of the north, central and east for the next 24 hours, with flash-flood and flood-river risk near hills and low-lying areas. Storm Narra will not hit Thailand directly. Waves of 2-3 metres in the upper Andaman mean small boats should stay ashore. If your site, stock or deliveries sit in flood-prone low ground or on the Andaman coast, move goods and plan delivery timing around the next day's forecast.
