26 September – 1 October 2011
Typhoon Pedring (international name, Nesat) exited the country the same time as Typhoon Quiel (international name, Nalgae) made its landfall in Isabela. Pedring came on September 27 and Quiel just a few days later on October 1, dumping even heavier rains and slamming strong winds into Luzon.
These typhoons caused severe problems in most areas of Central and Northern Luzon, with barangays in Bulacan submerged in roof-deep floodwater. The continuous rains caused Bulacan, Nueva Ecija, Pangasinan, and Pampanga to be inundated by floodwaters for weeks. Reports showed that the main cause of floods in the four provinces was the swelling of the Angat and Pampanga rivers.
The twin typhoons claimed 97 lives in Central Luzon and left 209,470 individuals in cramped evacuation centers for week. The typhoon also destroyed crops, infrastructure and access roads along its path. Destruction from both typhoons reached a total of more than PhP15 billion (Philippine Red Cross, 2011).
