The northeast monsoon or "amihan" may bring cloudy conditions and rains over the northern part of Luzon, including some areas in Bicol, said the Philippine Atmospheric, Geophysical and Astronomical Services Administration (PAGASA) on Tuesday morning, Oct. 26.
It will be rainy over Aurora, Quezon, Camarines Norte, Camarines Sur, Catanduanes, Cagayan Valley, and Cordillera Administrative Region in the next 24 hours.
PAGASA warned against possible flash floods or landslides during moderate to at times heavy rains.
Partly cloudy to cloudy skies with isolated light rains may also prevail over Ilocos Region.
Meanwhile, Metro Manila and the rest of the country will have partly cloudy to cloudy skies with isolated rain showers or thunderstorms due to localized thunderstorms.
Those in these areas were also warned against possible flash floods or landslides during severe thunderstorms.
Senior weather specialist Chris Perez said PAGASA continues to monitor the two tropical cyclones outside the Philippine area of responsibility.
The tropical depression was last spotted at 630 kilometers (km) west of Kalayaan Islands, Palawan, while the tropical storm with an international name "Malou" was estimated at 1,760 km east of northern Luzon.
Perez said the weather disturbances may not directly affect the country's weather nor enter the PAR but may trigger rough to very rough sea conditions.
He added that the country will be cyclone-free in the next two to three days.
Meanwhile, a gale warning is currently in effect due to strong to gale-force winds associated with the northeast monsoon, causing rough to very rough seas over the northern seaboards of northern Luzon, particularly Batanes, Babuyan Islands, and the northern coast of Ilocos Norte.
Under these conditions, fishing boats and other small seacrafts should not venture out into the sea while larger sea vessels should watch out for big waves.
Perez said more areas may be placed under gale warning in the next weather bulletin.
