Residents of areas affected by the southwest monsoon should be on alert for flash floods and landslides, too.

The rest of Luzon, including Metro Manila, might have light to heavy rain with occasional gusty winds starting Friday. PAGASA earlier said Metro Manila could be placed under Signal No. 1 if Ompong's outer rainbands affect it.

PAGASA also noted that since this is still a "long-range forecast," it could change. The public should closely monitor updates. (READ: Will Typhoon Ompong be the same as Super Typhoon Lawin?)
