MANILA, Philippines — Cloudy skies and heavy rains caused by a shear line are expected to continue in some areas that have been inundated by floodwaters, the state meteorological department said Wednesday.
A shear line is the convergence of hot and cold wind.
In a meteorological advisory, Pagasa predicted cloudy skies with scattered rain showers and thunderstorms in Visayas, Bicol region, Mimaropa (Occidental Mindoro, Oriental Mindoro, Marinduque, Romblon and Palawan), Quezon and Zamboanga Peninsula.
Pagasa warned that possible flash floods or landslides could occur due to moderate to sometimes heavy rains in these areas.
Floodwaters inundated low-lying communities in the Bicol region on Wednesday morning, while severe flooding inundated Samar and Panay islands in the Visayas.

Meanwhile, the northeast monsoon, or amihan, persists in Cagayan Valley, Aurora, Metro Manila and the rest of Luzon, bringing cloudy skies with light rains.
Pagasa predicted that the rest of Mindanao will have partly cloudy to cloudy skies with isolated rain showers or thunderstorms due to localized thunderstorms.
Meteorological expert Obet Badrina said the northeast monsoon could weaken in the coming days, which would reduce the rains brought by the shear line.
“We expect it to be possible for the north to weaken in the coming days so that it is possible to reduce the rainfall caused by the shear line,” Badrina said.
(We expect the amihan to weaken over the next few days, which could weaken rainfall due to the shear line.)
Badrina added that the meteorological agency is not currently monitoring any low pressure areas within the Philippines’ area of responsibility and such conditions could continue until the weekend.
As for the country’s coastline, a gale warning is still in force in the following areas:
- Ilocos Norte
- Ilocos South
- North coast of Quezon including Polillo Islands
- Calaguas Islands
- Research-Research, Albay
- Eastern coast of Sorsogon
- North and east coasts of Catanduanes
