Thailand’s authoritative weather agency, the Thai Meteorological Department (TMD), has issued stern warning of intensified rainfalls that stand as imminent menace to 46 provinces across the country. TMD’s expertly crafted weather models project a surge in rainfalls over 70% of the areas, even afflicting the capital city, Bangkok with a sudden flash floods alert, courtesy of fearsome forest runoffs.
Upon close examination, the TMD specialists indicate that the current precarious weather conditions draw upon several contributing factors. These include a tropical storm coursing through the northern and upper northeastern parts of the country, couched with a low-pressure trough assaulting central parts of Vietnam. On top this, moderate south-westerlies overlooking the Andaman Sea, Gulf of Thailand, and Thailand are also influencing factors. These collectively have boosted rainfall intensity, thereby triggering intermittent occurrences of heavy to extremely heavy precipitation in some regions.
The TMD, through its public service messaging, is urging residents within these affected areas to maintain a high alert stance against possible adverse effects of intense rainfalls and accumulated precipitation. Specifically, expected dangers include sudden flash floods and rushing forest runoffs, amplified in hilly terrains near water bodies and regions with a lower altitude. In addition, the significant wind waves present in the Andaman Sea and the Gulf of Thailand have surged, with wave heights touching 1-2 meters. Any area currently witnessing thundershowers stands a chance of facing elevated waves beyond 2 meters. Hence, the TMD advises sailors in these regions to maintain cautious navigation, more so in regions with ongoing thundershowers.
The 24-hour weather prediction for Thailand, set off at 6am today, anticipates a 60% probability of thundershowers in the north alongside heavy rain in select districts. These include places like Mae Hong Son, Chiang Mai, Lampoon, Lampang, Sukhothai, Tak, Kamphaeng Phet, Phitsanulok, and Petchabun. The temperature variations across these regions could range between 24-26 degrees Celsius for the lows and 31-36 degrees Celsius for the highs. Moreover, dominant south-westerly winds could waft across these areas at a speed of 10-20 kilometres per hour.
The eastern regions of Thailand are projected to witness thundershowers across 70% of the area and bouts of heavy rainfall in finite zones, including provinces like Nakhon Nayok, Prachin Buri, Sa Kaeo, Rayong, Chanthaburi, and Trat. The temperature extremes are expected to oscillate in between 25-28 degrees (minimum) and 31-33 degrees Celsius (maximum). The southwesterly winds blowing over the Eastern sea could produce waves typically within the 1-2 meters range, but could exceed 2 meters during thundershowers.
Bangkok, along with its peripheral provinces, is also threatened by intense rainfall across 70% of the area, inclusive of some patches of heavy shower. The anticipated temperature fluctuations in these areas should range between 27-28 degrees Celsius(low) and 32-34 degrees Celsius(high) amid southwesterly winds blowing at a speed of 10-25 kilometres per hour.
