While the sun is up over Bacolod this morning, Philippine Atmospherical Geophysical Services Administration said that the trough of typhoon “ROLLY” will bring light to moderate with at times heavy rains over Negros Occidental until tonight.
It said flooding (including flash floods), rain-induced landslides, and sediment-laden streamflows (i.e. lahar) may occur during heavy or prolonged rainfall especially in areas that are highly or very highly susceptible to these hazards.
PAGASA Regional Services Divisions may issue local thunderstorm/rainfall advisories and heavy rainfall warnings as appropriate, the weather advisory added.
It is expected to move west-southwestward today towards the sea off the coast of Bicol Region. Beginning tomorrow early morning, it will gradually turn towards the west-northwest, bringing its inner rainbands-eyewall region near or over Catanduanes and the Camarines Provinces during the morning-afternoon hours and over Quezon-southern Aurora area during the afternoon-evening hours.
The center of the eye of the typhoon is forecast to pass very close or over the Calaguas Islands tomorrow afternoon and make landfall over Polillo Islands and mainland Quezon tomorrow evening. After crossing Central Luzon, the center of “ROLLY” is forecast to exit the mainland Luzon landmass on Monday morning.
Owing to very favorable conditions, there is remains a possibility that this typhoon will reach Super Typhoon category over the next 12 hours, it added. However, “ROLLY” is more likely to be near Super Typhoon strength (185-215 km/h) by time it grazes Bicol Region and makes landfall over Quezon.
