The Thai Meteorological Department (TMD) reported 61mm of rainfall at the weather-monitoring station near Phuket airport yesterday, and more than 40mm of rainfall this morning.
The TMD currently forecasts heavy isolated thundershowers to continue across the island through to Monday (Aug 8) as the southwest monsoon prevails over the Andaman Sea.
The heavy weather conditions are easing, but waves are still forecast to reach over two metres in thundershower areas. All vessels in the area are warned to beware thunderstorms, and small boats are advised to stay ashore.
Lifeguards at many of the popular beaches along the west coast have posted red ‘no swimming’ flags to warn people to not enter the water where it is dangerous to swim.
