Tropical Depression to Bring Severe Rain and Wind to the Philippines

On the morning of November 24, a tropical depression was located near the eastern coast of Mindanao, the Philippines. It is expected that it will move west-northwestward through the central part of the Philippine Islands. It may intensify into Typhoon No. 27 of this year within the next 24 hours, with the maximum intensity reaching that of a strong tropical storm (Figure 1). Over the next three days, the Philippines will experience heavy to torrential rain, with localized extremely heavy downpours (Figure 2), accompanied by strong winds of 6-7 levels, with gusts reaching 8-9 levels (Figure 3). Additionally, influenced by the tropical low-pressure system, regions including the Malay Peninsula, Sumatra, Sri Lanka, and southeastern India will continue to face heavy to torrential rain, with localized extremely heavy downpours. Most areas will accumulate rainfall of 100-160 mm, with some regions reaching 200-250 mm, and the maximum could exceed 400 mm (Figure 4). Attention should be given to the adverse impacts of the severe weather on local power facilities, transportation, and other sectors, as well as the prevention of secondary disasters such as flooding, landslides, and mudslides that may be triggered by the heavy rainfall.
