MANILA (UPDATE) — Typhoon Ulysses, which further intensified as it makes landfall over Quezon, could cause storm surge with heights of up to 3 meters in several coastal areas in Luzon, the state weather bureau warned Wednesday.

In its 11 p.m. weather bulletin, PAGASA said the coastal areas of Aurora, Quezon including Polillo Islands and Camarines Norte are at high risk of experiencing storm surge of up to 3 meters due to the typhoon. 

Ulysses, which currently packs maximum winds of 150 kph near the center and gusts of up to 205 kph, will trigger storm surges as high as 2 meters in the following coastal areas:

There is also a moderate risk of storm surge over the coastal areas surrounding Laguna de Bay, according to PAGASA.

PAGASA said these storm surges "which may be accompanied by swells and/or breaking waves near the coast can cause life-thretening and damaging coastal inundation".
