TWO tropical cyclone-like vortices (TCLVs) are likely to emerge next week, with a “low chance” of developing into a tropical cyclone, according to the Philippine Atmospheric, Geophysical and Astronomical Services Administration (PAGASA).

In a threat potential forecast effective on Monday, the agency said the two TCLVs may occur over the eastern boundary of the Philippine area of responsibility (PAR) between April 27 and May 3.

It noted that both TCLVs have a low chance of developing into a tropical cyclone within the forecast period.

“Therefore, the TC threat potential is less likely during the forecast period,” PAGASA said in the forecast.

The TC threat potential forecast is released to identify the likelihood of tropical cyclone formation within the Philippine area of responsibility. It also tracks possible cyclone paths and movement over the next two weeks.

Meanwhile, easterlies continue to affect Southern Luzon, Visayas, and Mindanao, bringing warm winds from the Pacific Ocean and causing rainshowers in affected areas, PAGASA said in a separate 4 a.m. weather forecast.

In the next 24 hours, partly cloudy to cloudy skies with isolated rainshowers or thunderstorms are expected in Metro Manila, Calabarzon, Mimaropa, the Bicol Region, Visayas, and Mindanao.

PAGASA warned of possible flash floods or landslides during severe thunderstorms. The rest of Luzon may also experience localized thunderstorms, bringing partly cloudy to cloudy skies with isolated rainshowers or thunderstorms.

As for the country’s heat index, Sangley Point in Cavite City recorded the highest for four consecutive times in the computed five-day observed and forecast period.

The heat index ranged from 43°C to 44°C since April 19.

The area is still forecast to reach 43°C on Wednesday, PAGASA said.

Amid high heat index temperatures, PAGASA earlier reminded the public to wear light-colored clothing and bring sun protection when going outdoors. — Edg Adrian A. Eva
