Tropical Depression Will Impact the Philippines and Indochina Peninsula

At 8:00 AM on October 17th, the center of a tropical depression was located approximately 1140 kilometers east of Manila, the Philippines. It is forecasted to move rapidly westward at a speed of around 30 kilometers per hour, gradually intensifying. The system is expected to strengthen into the  typhoon within the next 24 hours (Figure 1).

Affected by this system, significant wind and rain are expected from October 17 to 23 in the Philippines, the coastal regions of southern China, central Vietnam, southern Laos, and Cambodia. Heavy rainfall is anticipated in some areas, with parts experiencing very heavy downpours. The cumulative rainfall in most of these regions is forecast to reach 60-100 mm, with some areas receiving 120-160 mm and localized totals exceeding 250 mm (Figure 2). Attention should be given to the adverse impacts of the severe weather on power facilities, transportation, and other industries, as well as the potential for heavy rainfall to trigger secondary disasters such as flooding, landslides, mudslides, and urban waterlogging.
