The Thai Meteorological Department (TMD) today sent out a substantial rain warning for a staggering 32 provinces, as the southern region is predicted to witness hefty rainfall covering an extensive 70% of its geography. Thai locals in the affected regions are being sternly advised to stay alert for probable heavy water accumulation, an event that could trigger unexpected floods.
The most recent 24-hour forecast from the TMD points towards a continuous covering of high-pressure cold air mass over the upper northern and northeastern areas of Thailand. At the same time, a trough is currently moving across the upper southern region, the Gulf of Thailand, and the eastern territories, marking its entry into a low-pressure zone within the South China Sea.
These meteorological phenomena, paired with the southwestern monsoon blanketing the lower southern regions, the Gulf of Thailand, and the Andaman Sea, result in ongoing thunderstorms across the length and breadth of Thailand. More so, the south and east are recording heavy to incredibly intense showers.
Citizens inhabiting these areas are issued warnings concerning the hazards of excessive rain and water buildup, potentially leading to abrupt flood situations and forest runoff. The risks are especially prominent in regions close to hillsides, watercourses, and valleys. Travelers venturing through these areas are to exercise utmost caution, especially during thunderstorms.
Concerning the sea conditions, the Andaman Sea and the Gulf of Thailand are anticipated to have wave heights fluctuating between 1-2 meters. This could further rise above 2 meters during thunderstorms, requiring seafarers to proceed with care and steer clear of tumultuous regions.
In the northern reaches, expect thunderstorms in about 30% of the area, primarily in Mae Hong Son, Chiang Mai, Lamphun, and Tak, with temperatures swinging between 23-24 degrees Celsius and a high of 30-35 degrees Celsius. These precipitation conditions stem from easterly winds traveling at a rate of 10-20 kilometers per hour.
The northeastern quadrant will witness thunderstorms spread over 10% of the area, notably in Amnat Charoen, Sisaket, and Ubon Ratchathani. The mercury is likely to hit between 21-24 degrees Celsius and 32-34 degrees Celsius, with winds hailing from the northeast blowing at a steady 10-20 km per hour.
Moreover, the central belt is preparing for storms in 20% of the area, predominantly in regions such as Nakhon Sawan, Uthai Thani, Kanchanaburi, Ratchaburi, Samut Songkhram, and Samut Sakhon. Here, the temperature fluctuates between 23-27 degrees and escalates to 31-35 degrees Celsius, in tandem with easterly winds clocking 10-20 km per hour.
The eastern seaboard forecasts thunderstorms sweeping across 30% of its territory, and potential heavy rain in specific spots such as Rayong, Chanthaburi, and Trat. The temperatures are predicted to hover between 24-26 degrees and 33-35 degrees Celsius, complimented by easterly winds blowing with a force of 15-30 km per hour. Heading out to sea, you will encounter waves of around 1-meter height – a figure expected to surge beyond 2 meters in areas with thunderstorms.
Turning our attention to the southern region (east coast), it is predicted to experience thunderstorms enveloping a whopping 70% of the whole area, and hefty showers in select locales like Prachuap Khiri Khan, Chumphon, Surat Thani, Nakhon Si Thammarat, Pattani, Yala, and Narathiwat. Onto the temperature scale, expect figures to fluctuate between 23-25 degrees and 32-35 degrees Celsius, with erratic winds blowing at speeds of 15-30 km per hour. The marine environment forecasts waves reaching 1 meter in height, potentially exceeding 2 meters amidst thunderstorms.
Examining the southern region (west coast), the climate projections point towards thunderstorms notifying 70% of the entire area and possible heavy to very heavy rainfall in specific areas such as Ranong, Phang Nga, Phuket, Krabi, Trang, and Satun. Temperatures are likely to vacillate between 23-25 degrees and touch down on 30-32 degrees Celsius, under the influence of western winds with a velocity of 15-35 km per hour. Mariners are advised to brace for waves which can fluctuate between an estimated 1-2 meters in height, potentially breaching the 2-meter mark in storm-prone regions.
Lastly, venturing into Bangkok and its nearby regions, the chances of thunderstorms are faint, at an approximate probability of 20%. Here, the day’s mercury is predicted to oscillate between 24-28 degrees and 32-34 degrees Celsius, propogated by easterly winds consistently blowing at a speed of a brisk 10-20 km per hour.
