PRESS RELEASE
24 May 2017

START OF SOUTHWEST MONSOON

Southwesterly windflow has been dominant over the West Philippine Sea for several days now. This is due to the formation of semi-permanent trough over Northern Luzon-Taiwan area and the eastward migration of the North Pacific High Pressure Area which are the prominent indicators of the southwest monsoon onset in the country. 

Likewise, the prevailing weather condition in most parts of Luzon and Visayas particularly the western section is now warm and humid as characterized by occasional to frequent occurrences of afternoon-evening or early morning rainshowers and thunderstorms. These developments signify the approaching onset of rainy season under Type 1 climate covering the western parts of Luzon and Visayas.
