Strengthening southwest monsoon brings heavy rain to northern Thailand as Matmo weakens
Thai Meteorological Department warns of isolated heavy rain in northern and northeastern Thailand; Matmo downgraded over northern Vietnam.
The Thai Meteorological Department reported on Tuesday that the moderate southwest monsoon prevailing over the Andaman Sea, Thailand, and the Gulf is strengthening. Isolated heavy rain is expected in the northern and upper northeastern regions of the country, prompting officials to urge residents to remain cautious.
The Department also warned that the strengthening winds are likely to create waves of 1-2 metres in the upper Andaman Sea, while waves in the lower Andaman Sea and the Gulf are expected to reach around 1 metre, rising above 2 metres in areas affected by thundershowers. Mariners were advised to proceed with caution and avoid thundershowers whenever possible.
In addition, at 1:00 a.m. on October 7, Tropical Depression Matmo was downgraded to an active low-pressure cell over upper Vietnam, reducing the immediate risk of severe weather impacting Thailand. Authorities continue to monitor the situation closely, advising both residents and maritime operators to remain alert for any sudden changes in weather conditions.
