The low pressure area (LPA), which was formerly tropical depression "Crising" has dissipated early Saturday morning, May 15, said the Philippine Atmospheric, Geophysical and Astronomical Services Administration (PAGASA).
Hot and humid weather conditions are expected to prevail over a huge part of the country due to the prevalence of warm and humid easterly winds.
PAGASA said Palawan, Agusan del Norte, Agusan del Sur, Dinagat Islands, Surigao del Norte, and Surigao del Sur will have cloudy skies with scattered rain showers and thunderstorms.
The public is warned against possible flash floods or landslides during moderate to at times heavy rains.
PAGASA said Metro Manila and the rest of the country will continue to experience hot and humid weather conditions except for some isolated rain showers or thunderstorms mostly in the afternoon or evening.
Based on its extended weather outlook for key areas from May 16 to 19, PAGASA said that maximum air temperatures may reach 35-36 degrees Celsius (℃) in Metro Manila, 38℃-39℃ in Tuguegarao City, 27℃-28℃ in Baguio City, 32℃-33℃ in Tagaytay City, 32℃ in Puerto Princesa City, 32℃-33℃ in Metro Cebu, 33℃-34℃ in Metro Davao, and 33℃-34℃ in Zamboanga City.
How to stay cool amid the scorching weather
The highest recorded air temperature in the Philippines was 42.2 degrees Celsius in Tuguegarao, Cagayan on May 11, 1969.
Meanwhile, the highest recorded air temperature in Metro Manila was 38.5 degrees Celsius on May 14, 1987.
Air temperature is different from heat index as the latter is the measurement of how hot it feels when relative humidity is factored in with the actual air temperature.
The Heat index is at least 3℃ to 4℃ higher than the actual air temperature.
The highest heat index so far in 2021 was recorded in Dagupan City, Pangasinan on May 14 at 53℃.
