The Philippine Atmospheric, Geophysical and Astronomical Services Administration (PAGASA) said while the northeast monsoon caused a slight drop in air temperature on Wednesday, March 20, it may have its final wave in the coming days. 

PAGASA weather specialist Benison Estareja said in its public forecast on Wednesday morning that the northeast monsoon, also known as "amihan," has re-strengthened, affecting a significant portion of Northern and Central Luzon where light rains are experienced.

However, he said since the warm and dry season may soon officially begin, this could be the last wave of amihan.

“By tomorrow, iiral pa rin ang northeast monsoon sa malaking bahagi ng Luzon pero inaasahan na hihina agad ito pagsapit ng Friday at maaaring ito na ang katapusan o pagtatapos ng northeast monsoon season at iiral na iyong warm dry season or tag-init sa ating bansa (By tomorrow, the northeast monsoon will still prevail in huge part of Luzon but we expect that it will suddenly weaken on Friday, and it may be the end of its season, as the warm dry season will prevail in the country),” Estareja said. 

Based on the PAGASA’s extended weather outlook from March 21 to 23, the actual air temperature in some key areas are: 23–32°C in Metro Manila, 24-32° in Legazpi City, 14–24°C in Baguio City, 25–32°C in Metro Cebu, 25–32°C in Iloilo City, 24–32°C in Tacloban City, 24–34°C in Metro Davao, 24–35°C in Zamboanga City, and 24–31°C in Cagayan de Oro City. 

24-hour forecast 

Over the next 24 hours, PAGASA said Eastern Visayas, Sorsogon, and Masbate will have cloudy skies with scattered  rain showers and thunderstorms due to the easterlies, which are warm winds from the Pacific Ocean. 

PAGASA warned the public of flash floods or landslides due to moderate to heavy rains.

In Cagayan Valley, Apayao, and Kalinga, flash floods or landslides may still occur in times of moderate to heavy rains, as cloudy skies with rains will be felt due to amihan. 

Aurora and Northern Quezon will also have cloudy skies with light rains, while Metro Manila, Ilocos Region and the rest of Cordillera Administrative Region, Central Luzon, Cavite, Laguna, Batangas, Rizal, and Quezon will have partly cloudy to cloudy skies with isolated light rains due to amihan. 

PAGASA said the rest of the country will experience partly cloudy to cloudy skies with isolated rain showers or thunderstorms due to easterlies and localized thunderstorms. 

The public was also warned of flash floods or landslides that may occur during severe thunderstorms.
