CATANDUANES, EXTREMELY DANGEROUS SITUATION

Rolly now a super typhoon, Signal No. 5 to be raised over 3 areas


Typhoon Rolly has been declared a Supertyphoon by PAGASA early Sunday morning.

The weather bureau added that Tropical Cyclone Wind Signal (TCWS) No. 5 will be raised over Catanduanes, Eastern Camarines Sur, and Albay. Catastrophic wind damage is expected.

 

 

Earlier, in the 2 a.m. Severe Weather Bulletin, PAGASA said Catanduanes is under an extremely dangerous situation as Typhoon Rolly is hours from landfall over the province.

Within the next 12 hours, violent winds and intense to torrential rainfall associated with the region of the eyewall and inner rain bands of the typhoon will be experienced over Catanduanes, Camarines Norte, Camarines Sur, Albay, and the southern portion of Quezon. This a particularly dangerous situation for these areas.

As of 1 a.m. on Sunday, the center of the eye of Typhoon Rolly was located based on all available data including those from Virac and Daet Doppler Weather Radars at 110 kilometers east Northeast of Virac, Catanduanes with maximum sustained winds of 215 kilometers per hour near the center and gustiness of up to 265 kph and moving in the west southwest direction at the speed of 25 kph.

The center of the eye of Typhoon Rolly is forecast to make landfall at or near its current peak intensity over Catanduanes this early Sunday morning and over Camarines Sur.

Afterwards, the center will cross the Camarines Provinces before heading towards mainland Quezon this afternoon.

After crossing the CALABARZON area, the center of Rolly is forecast to exit the mainland Luzon landmass and emerge over the Philippine Sea on tomorrow early morning.

During its traverse of Southern Luzon, Rolly is forecast to weaken considerably and emerge as a severe tropical storm or minimal typhoon over the West Philippine Sea.

Hazards affecting land areas

On Sunday, the passage of Typhoon Rolly will bring heavy to intense with at times torrential rains over Bicol Region, CALABARZON, Metro Manila, Marinduque, Romblon, Mindoro Provinces, Bataan, Bulacan, Aurora, Northern Samar, Samar, Eastern Samar, Biliran, and the eastern portions of mainland Cagayan and Isabela.

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

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

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. 

Very destructive typhoon-force winds will be experienced in areas under TCWS No. 4, destructive typhoon-force winds in areas under TCWS No. 3, damaging gale- to storm-force winds in areas under TCWS No. 2, and strong breeze to near gale conditions in areas under TCWS No. 1.

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 No. 1.

In the next 24 hours, there is a high risk of storm surge of more than 3.0 m over the coastal areas of Catanduanes and Camarines Norte and the northern coastal areas of Quezon including Polillo Islands and Camarines Sur; up to 3.0 m over the 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, Northern Samar, Eastern Samar, and Burias Island and the remaining coastal areas of Quezon, Camarines Sur, 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

On Sunday, 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.

Other tropical systems being monitored

As of 1 a.m. on Sunday, the center of Tropical Depression Atsani was estimated at 1,385 kilometers east of Southern Luzon with maximum sustained winds of 55 km/h near the center and gustiness of up to 70 kilometers per hour and moving west-northwestward at 20 kph.

Atsani and is forecast to enter the Philippine Area of Responsibility on Sunday  afternoon.

Once inside the PAR, Atsani will be given the domestic name Siony. It remains less likely to affect any portion of the country over the next 2 to 3 days. It is likely to re-intensify into a tropical storm in the next 12 to 24 hours. -- BAP, GMA News
