The weather bureau announced on Monday the termination of the northeast monsoon and the start of the warm and dry season.

Generally fair weather will prevail across the country and gradually, warmers days and isolated thunderstorms are expected, the Philippine Atmospheric, Geophysical and Astromonical Services Administration (PAGASA) said.

Some areas in Northern Luzon may still experience occasional northeasterly winds, it noted.

The bureau, in a statement, urged the public to take precautionary measures to minimize heat stress and optimize the use of water for personal and domestic consumption.

In a press conference, PAGASA Administrator Nathaniel Servando said the bureau will continue to monitor and provide updates on the expected high heat indices not just in Metro Manila but also in other parts of the country.

Heat index refers to the temperature felt by the human body when relative humidity is combined with actual air temperature.

PAGASA forecasts most parts of the country, especially in Northern and Central Luzon, to experience high temperatures in April through May.

Senior weather specialist Joseph Basconcillo said an extreme temperature of 40.5 °C may be experienced in Northern Luzon in May.

Hot and humid weather, lesser rains are expected until from April to May amid the dry season, he said. (PNA)
