Heavy rain and gusty winds are forecast for upper Thailand until Oct 15, with temperatures expected to drop in the North and the Northeast.
The Meteorological Department said on Thursday that another moderate high pressure system will extend over upper Thailand from Oct 12-15. Thundershowers and strong winds were possible in the North, the Northeast, the East and Central regions, including Bangkok and surrounding areas during this period.
After that, temperatures were expected to drop by 2-3°C in the North and the Northeast.
People in these areas should be ready for changeable weather conditions.
