Tropical Depression Ramil slightly intensified as it traversed the Calamian Group of Islands, the state weather bureau said on Wednesday afternoon.
Signal No. 1 remained over northern Palawan including Calamian Group of Islands and Southern Occidental Mindoro, the Philippine Atmospheric, Geophysical and Astronomical Services Administration (Pagasa) said.
Ramil was last spotted 25 kilometers south of Coron, Palawan, and has slowed down at 18 kilometers per hour (kph) westward.
The tropical cyclone has maximum sustained winds of 55 kph and gusts of up to 75 kph.
Residents with storm signals, as well as those in Central Luzon, Cagayan Valley and northern portion of Quezon including Polillo Island, were alerted for possible flashfloods and landslides.
Metro Manila and the rest of Luzon are expected to have light to moderate with possible occasional heavy rains and thunderstorms.
Pagasa warned of risky sea travel over areas under Signal No. 1 and the seaboards of northern and eastern seaboards of Luzon.
Heavy rain brought by Tropical Storm “Ramil” has caused flooding in Camarines Sur province, the Office of Civil Defense (OCD) Bicol said Wednesday.
OCD Bicol Director Claudio Yucot said seven villages were submerged in Baao town and two villages were flooded in Balatan town.
Iriga City and Garchitorena town, also in Camarines Sur, each had one flooded village. In Caramoan, the flood was described as knee-deep.
There is also a reported power interruption in Lagonoy town.
All boat trips connecting Oriental Mindoro and Occidental Mindoro have been canceled since Wednesday morning after the weather bureau raised typhoon signal number 1 over the provinces as Tropical Depression “Ramil” dumped rains over Southern Luzon since Monday night.
