Storm surge alert raised in Cadiz City

FIVE coastal villages in Cadiz City, Negros Occidental are among the more than 100 barangays in the Visayas where storm surge is predicted to occur with Tropical Depression Domeng moving toward land.

The list, released Monday by the Project Noah of the Department of Science and Technology (DOST), include barangays Banquerohan, Poblacion 4, Daga, Luna and Tiglawigan.

Other villages in the list are in Negros Oriental, Iloilo, Cebu and Leyte.


According to the Nationwide Operational Assessment of Hazards’ (Noah) website, the list “is a model run with 4,884 stations from specified localities with storm surge + tide values.”

The agency said the storm tide is expected to hit the areas tomorrow, April 9.

According to the Philippine Atmospheric, Geophysical and Astronomical Services Administration (Pagasa), a storm surge is the rise of seawater brought by strong winds.

Usually, storm surge happens if the seabed is shallow and the beachfront is wide.

During the super typhoon Yolanda last November, Tacloban City, for instance, was devastated as waves as high as 20 feet upturned cars and drowned animals and people who failed to escape the rampaging waters.

Storm surges happen when the weather disturbance produces a rise of water way above the predicted astronomical tide, according to the United States National Weather Service.

As an archipelago, the Philippines is vulnerable to storm surges but the effect is dependent on several factors such as the storm's pressure, size, intensity, forward speed and angle of approach to coast, shape of coastline, width and slope of the continental shelf and local features.

The DOST said this week’s storm tide prediction was generated using Japan Meteorological Agency Storm Surge Model results. (NLG/Sunnex/PNA)
