Typhoon 'Rolly' threatens Batangas-Cavite area

Hazards affecting land areas

Rainfall: Today, the passage of Typhoon 'Rolly' will bring heavy to at times intense rains over CALABARZON, Metro Manila, Marinduque, Romblon, Mindoro Provinces, Bataan, Bulacan, Aurora, and the eastern portions of mainland Cagayan and Isabela.

Moderate to heavy rains will be experienced over Cordillera Administrative Region, and the rest of mainland Cagayan Valley and Central Luzon.

Light to moderate with at times heavy rains will be experienced over Zamboanga Peninsula, Bangsamoro, Western Visayas and the rest of Luzon.

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.

Strong winds: Destructive typhoon-force winds will be experienced in areas under TCWS #3, damaging gale- to storm-force winds in areas under TCWS #2, and strong breeze to near gale conditions in areas under TCWS #1.

Potential impacts of the wind conditions to structures and vegetation under each wind signal are detailed in the TCWS section of this bulletin.

Elsewhere, strong breeze to near gale conditions due to the northeasterlies will be experienced over the rest of Northern Luzon that are not under TCWS #1.

Storm surge in the next 24 hours, there is a high risk of storm surge of:
  • up to 3.0 m over the northern coastal areas of Quezon including Polillo Islands, coastal areas of Metro Manila, Cavite, Bulacan, Pampanga, Bataan, the southeastern coastal area of Batangas (facing Tayabas Bay), and most of the southern coastal areas of Quezon;
  • up to 2.0 m over the coastal areas of Marinduque, Lubang Island, Albay, Masbate (including Ticao and Burias Islands), the northern coastal area of Mindoro Provinces, and the remaining coastal areas of Quezon, and Batangas.

Moreover, there is also a moderate to high risk of seiche or storm surge over the coastal areas surrounding Laguna de Bay and Taal Lake. These storm surges, which may be accompanied by swells and breaking waves reaching the coast can cause life-threatening and damaging coastal inundation.

Hazards affecting coastal waters

Today, rough to phenomenal seas (2.5 to 16.0 m) will be experienced over the seaboard of areas where TCWS is in effect and rough to very rough seas (2.5 to 5.0 m) over the remaining seaboards of Northern Luzon and the eastern seaboards of Eastern Visayas (that are not under TCWS) and Caraga.

Sea travel is risky for all types of seacrafts over these waters, especially those under TCWS.

Moderate to rough seas (1.2 to 2.5 m) will be experienced over remaining seaboards of the country.

Mariners of small seacrafts are advised to take precautionary measures when venturing out to sea. Inexperienced mariners should avoid navigating in these conditions.

'Bagyong Rolly' is the Philippines' 18th tropical cyclone for 2020, and the 5th for October.

On average, there are 20 tropical cyclones that could form or enter the PAR each year. Only half of those are projected to make landfall.

PAGASA declared the onset of rainy season on June 12.
