BANGKOK — Thailand’s weather experts have issued a warning for widespread thunderstorms across 36 provinces, with Bangkok expected to see heavy rain over 60 per cent  of the capital area.

Residents should be cautious of potential dangers from these thunderstorms, caused by a low-pressure system over northern Laos and Vietnam combining with the southwest monsoon, The Bangkok Post reported today.

Mariners sailing in both the Andaman Sea and the Gulf of Thailand are advised to be careful, as waves could reach about one metre high and might climb over two metres in areas hit by storms.

Authorities strongly recommend avoiding sailing in any regions where thunderstorms are actively occurring.

Here’s the weather outlook across Thailand from 6am today to 6am tomorrow:
