Although Typhoon Falcon (international name: Chan-hom) will not be expected to make landfall, its presence near the Philippines will enhance rains brought by the southwest monsoon (otherwise known as Habagat). This enhanced monsoon was also the case for the recent Typhoon Egay, as though it passed through northern Luzon, other areas in the Philippines experienced continuous or intermittent rainfall. PAGASA has warned the public about successive days of potentially heavy rains in some areas in the Philippines.

Habagat, as defined by PAGASA, affects the Philippines from July to September. It is characterized as very warm and humid, and it occurs when warm moist air flows over the country from the southwest direction. Heavy rainfall due to Habagat may last for a week. Habagat also “brings the rainy season to the western portion of the country”.
