Meanwhile, another high-pressure system from China has covered upper Vietnam, Loas and the South China Sea. This forces the southerly and southeasterly winds to blow the humidity from the sea to the lower North, the Northeast, the Central and the East, causing isolated light rains in the areas.
The Department also mentioned that the weak northeast monsoon prevails across the Gulf of Thailand, leading to isolated thundershowers over the South.
The weather forecast for the next 24 hours is as follows:
North: Cool to cold weather with fog in the morning and thundershowers in 10 per cent of the areas; temperature lows of 12-17 degrees and highs of 30-36 degrees Celsius. Temperature on hilltops is likely to drop to 4-12 degrees Celsius.
Northeast: Cool to cold weather with fog in the morning and thundershowers in 10 per cent of the areas; temperature lows of 13-21 degrees and highs of 28-34 degrees Celsius. Temperature on hilltops is likely to drop to 8-14 degrees Celsius.
Central: Cool weather with fog in the morning and thundershowers in 10 per cent of the areas; temperature lows of 21-23 degrees, highs of 32-36 degrees Celsius.
