Most of Thailand, with the exception of the south, will become cooler tomorrow as temperatures are forecast to fall further by 2-4^oC in the Northeast and by 1-3^oC in the northern, eastern and central regions, including Bangkok and its peripherals.

The Meteorological Department attributed the cooler weather over the next 24 hours to a strong cold front from China, which is blanketing northern parts of Thailand.

In northern provinces, the department reports that temperatures this morning (Wednesday) fell by 1-3^oC, to 17-21^oC on the lowlands, while temperatures in the highlands range from 5-12^oC, with ground frost in some areas.

In the north-eastern region, the mercury this morning had dropped by 2-4^oC, to 13-17^oC on the lowlands, and between 7-13^oC in mountainous areas.

In the central and eastern regions, temperatures range from 18-20^oC and 17-21^oC respectively.

Temperatures in Bangkok and its suburbs ranged from 19-21^oC this morning, with strong winds.

Strong winds and rough seas are reported today in the Gulf of Thailand and the Andaman Sea, with waves between 2-3 metres high. Small vessels are advised to stay ashore.
