Storm surge hit Metro Manila with West of Central Luzon, Olongapo City, Bataan, Batangas and Cavite area. While typhoon Pedring wrestled the Northern Island of Luzon (September 27, 2011). A storm surge is an offshore rise of water associated with a low pressure system (typhoon, hurricane, cyclone or wili-wili). Storm surges are caused primarily by high winds pushing on the ocean's surface. The wind causes the water to pile up higher than the ordinary sea level plus the factor of high tide. It is this combined effect of low pressure and persistent wind over a shallow water body which is the most common cause of storm surge flooding problems. Storm surges are Tsunami Juniors but sometimes they are as size as Tsunami that can kills up to 6,000 to 12,000 casualties like in Galveston, Texas in1900. So don't play with the surges they are dangerous. Typhoon Pedring's storm surge fury destroyed the sea walls of the bay walk in Roxas Boulevard in Manila. Stone bricks are scattered like in a modern war scenario.
