TERMINATION OF THE NORTHEAST MONSOON
The resurgence of the Northeast Monsoon that affected the Northern and Central Luzon during the last few days has weakened. Latest weather map analyses and numerical model outputs indicate the establishment of North Pacific High Pressure Area during the weekend. These changes in pressure system with accompanying changes in wind pattern signifies the termination of the Northeast Monsoon.
The day-to-day weather will gradually become warmer and drier in the coming weeks partly due to the dominance of the extended ridge of North Pacific High Pressure Area and easterlies. This would also signify the start of the dry season. However, some isolated rainshowers and thunderstorms are expected in the afternoon or evening particularly over the eastern sections due to localize convection. Moderate to occasionally rough coastal waters particularly over the eastern section of Luzon, Visayas will occur due to moderate to strong easterly wind. Mindanao will experience scattered rainshowers and thunderstorms due to the northward migration of the Intertropical Convergence Zone (ITCZ) or passage of easterly waves.
PAGASA will closely monitor these conditions and regular updates and advisories shall be issued as appropriate. For further information, please contact PAGASA at telephone numbers (02) 434-0955 or (02) 927-1335.
