Typhoon "CO-MAY" will affect Northern and Central Philippines

Affected by Typhoon "CO-MAY" (No. 8) (Figure 1), moderate to heavy rain is expected in central and northern Philippines from July 24 to 25, with heavy downpours in some areas. Specifically, localized extremely heavy rain is anticipated in the western Cordillera, Ilocos, western Central Luzon, and southern Tagalog regions, accompanied by severe convective weather such as short-duration intense rainfall and thunderstorms with strong winds. The cumulative precipitation during this period is forecasted to be 60-100 mm, reaching 120-150 mm in the northwestern coastal areas, with localized totals exceeding 200 mm (Figure 2). Additionally, coastal regions in central and northwestern Philippines will experience strong winds of 6-8 gales , with gusts reaching 9-11 (Figure 3).

Attention should be given to the adverse impacts of strong winds and heavy rain on power facilities, transportation, and other industries in the aforementioned regions. Additionally, there is a risk of secondary disasters such as flooding, landslides, debris flows, and urban waterlogging that may be triggered by the intense rainfall.
