Typhoon "Fabian" (international name "In-fa") did not have a direct effect on the country but it enhanced the southwest monsoon or "habagat" that triggered widespread rains in several Luzon areas during the past five days.
Philippine Atmospheric, Geophysical and Astronomical Services Administration (PAGASA) weather specialist Ariel Rojas said 14 PAGASA monitoring stations have recorded more than 200 millimeters of rainfall from July 19 to July 23.
"Kaya malawakang pagbaha at pagguho ng lupa ang naiulat sa iba’t ibang bahagi ng ating bansa (That was why widespread floods and landslides have been reported in various parts of our country)," he said in the PAGASA's 5 p.m. weather forecast on Saturday, July 24.
Rojas also pointed out that most of the monitoring stations that registered the highest rainfall were those in the western section of Luzon due to the impact of the southwest monsoon enhanced by Fabian.
Below are the 14 stations that received the highest five-day accumulated rainfall due to habagat.
