During severe thunderstorms, flash floods or landslides may result.
Coastal waters will be slight to moderate throughout the country.
Sunrise was at 5:31 a.m. while sunset will be at 6:14 p.m.
El Niño
Meanwhile, PAGASA said the rainy season may be delayed due to the El Niño weather phenomenon.
"Sa kasalukuyan kasi, isa sa mga epekto ng El Niño, kapag nakakaranas tayo ng El Niño, posible 'yung pagka-delay ng rainy season," PAGASA weather specialist Veronica Torres said in an interview on Unang Balita on Monday.
(Currently, one of the effects of El Niño, when we experience El Niño, is the possible delay of the onset of the rainy season.)
"And also isa rin sa mga epekto 'yung (one of the effects is the) below normal na rainfall," she added.
Torres however said PAGASA climatologists will still assess the possible effects.
As to tropical cyclones, Torres said there is a low probability of any being formed this week.
"Sa susunod na week, although may nakikita tayong vortex, may kababaaan pa naman ang possibility," she said.
(Next week, although we are seeing a vortex, there possibility of it developing into a tropical cyclone is still low.)
This month though, one or two tropical cyclones may be formed or enter the Philippine Area of Responsibility (PAR), Torres said.
"Base po sa assessment ng ating mga kasama sa Climatological Department, ngayong Mayo, posible isa o dalawang bagyo ang posibleng pumasok o mabuo sa loob ng Philippine Area of Responsibility," she said.
(Based on the assessment of our colleagues in the Climatological Department, this May, one or two tropical cyclones may enter or develop inside the Philippine Area of Responsibility.)
La Niña
Torres said the La Nina weather phenomenon may be felt in June, July, and August.
"Base sa analysis ng ating mga kasamahang climatologists, by June, one or two 'yung posibleng pumasok na bagyo; July, two or three na bagyo 'yung pwedeng pumasok; August, two or three; September, two or three; then October, two or three puwedeng mabuo or pumasok sa ating Philippine Area of Responsibility," she said.
