PAGASA warns of rain from shear line
THE SHEAR LINE will continue to affect the Philippines over the next four days, bringing rain, thunderstorms and lightning to Bicol and parts of the Visayas as its axis shifts northward, the state weather bureau said on Sunday.
The Philippine Atmospheric, Geophysical and Astronomical Services Administration (PAGASA) said in a 5 a.m. weather forecast that the shear line’s interaction with the remnants of former Tropical Storm Nokaen, locally named Ada, would keep weather conditions unstable, particularly along the eastern seaboard, from Monday through Thursday.
Ada had weakened into a low-pressure area about 765 kilometers east of General Santos City and was no longer expected to redevelop. However, it continues to enhance cloud cover and rainfall over eastern Mindanao and nearby areas.
Eastern Luzon, from Cagayan Valley down to Bicol, will experience cloudy skies with intermittent rains, whilst western Luzon, including Metro Manila, was forecast to have generally fair weather with isolated light showers.
PAGASA said the shear line would trigger moderate to heavy rainfall over Dinagat Islands, Surigao del Norte, Surigao del Sur, Agusan del Norte, Agusan del Sur, Davao Oriental and Davao de Oro.
Rainfall in these areas could reach 50 to 100 millimeters within 24 hours, raising the risk of flooding and landslides, especially in vulnerable communities.
Marine conditions will remain hazardous, with gale warnings raised along the eastern seaboard of Mindanao, particularly near Dinagat Islands and Surigao del Norte, due to strong northeast monsoon winds generating high waves.
In other areas, sea conditions were expected to be moderate to rough. PAGASA advised small fishing vessels and other small seacraft to exercise caution or avoid sailing during the period. — Chloe Mari A. Hufana
