MANILA, Philippines 鈥� Some areas in Luzon are at 鈥渕oderate鈥� to 鈥渉igh risk鈥� of storm surge within the next 48 hours even as Typhoon Pepito (international name: Man-yi) moves away from the coasts of La Union and Pangasinan , the state weather bureau warned early Monday morning.
Philippine Atmospheric, Geophysical and Astronomical Services Administration (Pagasa) defines a storm surge as 鈥渢he abnormal rise in sea level that occurs during tropical cyclones or typhoons.鈥�
鈥淚t is caused by strong winds and low atmospheric pressures produced by tropical cyclones. As the tropical cyclone approaches the coast, strong winds push the ocean water over the low-lying coastal areas, which can lead to flooding,鈥� Pagasa said.
Below is the list of areas that may experience storm surge in the next 48 hours:
2.1 to 3 meters
- Ilocos Sur
- La Union
- Pangasinan
1 to 2 meters
- Aurora
- Ilocos Norte
- Ilocos Sur
- Isabela
- Pangasinan
- Zambales
The public is advised in these areas to stay away from the coast or beach, cancel all marine activities, and move to higher grounds away from the coast and storm surge-prone areas.
In its 2 a.m. cyclone update, Pagasa said Pepito is now 105 kilometers west southwest of Sinait, Ilocos Sur.
It is moving northwestward at 30 kilometers per hour (km/h), packing maximum sustained winds of 150 km/h near the center and gustiness of up to 185 km/h.
Pepito is expected to exit the country鈥檚 boundary by Monday morning or noon.
