The state weather bureau warned Friday that tropical storm Paeng could cause storm surges of up to 2 meters in some coastal areas of Luzon and Visayas.

PAGASA said in a 2 p.m. advisory that a “minimal to moderate risk” of storm surge up to 2 meters high may cause flooding in low-lying and exposed coastal areas of Bicol Region, Quezon, including Pollilo Islands, the eastern portion of Aurora, the northern and eastern portions of Northern Samar, and the eastern portion of Eastern Samar. bulletin.

Storm surge, also known as “daluyong,” refers to rising seas caused by a storm, which creates a wall of water several meters higher than the normal tide level.

Large swells travel faster than the cyclone and can be seen up to 1,000 kilometers ahead of a major storm. The surge can reach dozens of kilometers inland, bombarding homes and making roads impassable.

“Storm surge becomes more dangerous when it arrives on top of a high tide,” PAGASA said on its website. “When this happens, it may flood areas that would otherwise be dry or safe. On top of the storm surge, big and strong waves generated by powerful winds also come with it.”

A 1 to 2 meter storm surge could cause moderate to significant damage to communities, disrupt all marine-related activities, and cause flooding in low-lying areas, according to the report.
