MANILA, Philippines– The Department of Science and Technology’s Project Noah (Nationwide Operational Assessment of Hazards) on Monday released a list of areas where storm surge and tides with combined heights reaching over two meters are predicted due to Tropical Storm “Domeng” (international name: Peipah).

Over 100 localities in the Visayas were listed where the storm surge and tides are expected to hit on Wednesday.

The state weather bureau defines the storm surge as an “abnormal rise of water” due to a tropical cyclone and it is an oceanic event responding to meteorological driving forces.”

“Potentially disastrous surges occur along coasts with low-lying terrain that allows inland inundation, or across inland water bodies such as bays, estuaries, lakes and rivers. For riverine situations, the surge is sea water moving up the river,” the Philippine Atmospheric Geophysical and Astronomical Services Administration said.

A fresh water flooding moving down a river due to rain generally occurs days after a storm event and is not considered a storm surge. For a typical storm, the surge affects about 160 km of coastline for a period of several hours, Pagasa also said.

“The list is a model run with 4,884 stations from specified localities with storm surge + tide values,” Project Noah said.

These are the areas that may be hit by the storm surge and tides on Wednesday:
