The state weather agency Philippine Atmospheric, Geophysical and Astronomical Services Administration (PAGASA) warned the public to take extra precaution because the heat index may reach 42 degree Celsius from 12:00 p.m. to 3:00 p.m. this week,

Sonny Pajarilla, local weather chief, said Thursday residents should wear light-colored clothes, put sunblock lotion when out of their homes and offices, and to bring drinking water.

“Ang maximum ay hanggang 42 degree Celsius ang ating inaasahan between alas dose hanggang alas dos, alas tres ng hapon doon nagpi-peak ang heat index na tinatawag. Ang maximum temperature at the same time… itong hindi naman masyadong mababa ang ating humidity, ang ating humidity ay pumapalo sa 55 percent. It feels like 41 to 43 degrees Celsius,” he said.

The sunny weather will continue to be experienced until the middle of next week, but a shallow low-pressure area (LPA) system is expected to bring rains in the province towards the weekend.

Isolated rain showers due to localized thunderstorms will be experienced in the afternoon, especially in elevated areas.

“Next week ay maaaring may shallow low-pressure kung saan dadaan dito at magpipihit ng ating hangin na medyo magsa-southwest so consequently, magkakaroon ng convergence at maaring may pag-ulan na tayo towards the weekend of next week pero this week hanggang sa mid of next week ay magiging mainit pa rin tayo, magiging maaliwalas ang lagay ng panahon,” he added.

Pajarilla said the month of April accumulated a volume of one millimeter (mm) which is only two percent of the normal rainfall at 54 mm.

Since January, it was only in the month of March that rainfall was recorded with volume exceeding 40 percent because of the rain shower that occurred, adding that the drought will prevail in May but rain showers can be expected.

Pajarilla said that by June there will be a 50-60 percent chance of rain.
