Flooding or landslides induced by rains may occur in those areas.

Windy.com, a Czech-based website aggregator of climate data, also predicts moderate rains over north Palawan and eastern section of Mindoro Oriental in the afternoon.

Pagasa said the rest of Luzon will have party cloudy skies with a bit of light rains.

Visayas and Mindanao will be cloudy, but can get wet and experience severe thunderstorms.

Windy.com said North Cotabato and South Cotabato might get heavy rainfall ( between 15mm-17.6mm) with thunderstorms around 2pm.

Flood alerts

A red flood alert was raised in the Bicol region, particularly in Albay, Camarines Sur, Sorsogon, Catanduanes and Camarines Norte. Red means the treat of flooding is “extreme,” as the rivers and tributaries have overflowed from the rains for the past few days.

+ Albay – Rivers and its tributaries particularly Guinale and Upper Donsol.
+ Camarines Sur – Rivers and its tributaries particularly Lower Kilbay Catabangan, Ragay, Tinalmud, Tambang and Lagonoy.
+ Sorsogon – Rivers and its tributaries particularly Lower Donsol, Ogod, Putiao, Cadacan, Banuang-Daan, Fabrica (Tugbugan) and Matnog.
+ Catanduanes – Rivers and its tributaries particularly Cabuyan, Bato and Pajo.
+ Camarines Norte – Rivers and its tributaries particularly Labo and Daet Basud.

An orange flood alert is also up in Quezon and Rizal provinces. Orange means the threat of flooding is “severe.”

What’s driving the rains?

There are two weather disturbances in the country today — the prevailing Northeast Monsoon in Luzon, and the Shearline.

The prevailing weather condition is the Shearline or the thin horizontal layer of clouds where the cold winds and warm winds merged. The Shearline is causing the rains in the Bicol region, Metro Manila, CALABARZON, Nueva Ecija, Bulacan, and Aurora.

Meanwhile, the persistent Northeast Monsoon north of Luzon is bringing rains over Apayao and Cagayan Valley.

It seems that the two LPA that Pagasa has been monitoring has dissipated. Pagasa’s weather advisory Tuesday 11pm still saw the LPA over the coastal waters off Silago, Southern Leyte. The other LPA was last seen 385 kilometers west off Puerto Princesa City in Palawan. However, the 4am Pagasa weather forecast no longer mentioned the two LPA’s.
