MANILA -- (UPDATE) Cold winds blowing from the northeast weakened approaching typhoon Rosita (Yutu), but it is still powerful enough to cause landslides, floods and storm surges, the state weather bureau said.
The storm's maximum sustained winds have gone down to 150 kilometers per hour from 170 kph, while its gusts are now at 185 kph from 210 kph, due to the amihan, PAGASA said.
Rosita was spotted 410 kilometers east Northeast of Casiguran, Aurora at 1 p.m. Monday, on course to hit the Isabela-Aurora area on Tuesday, the weather bureau said.
The cold and dry amihan winds weakened the warm core of the typhoon, PAGASA Weather Services assistant chief Rene Paciente told reporters.
However, the 18th storm to enter the country this year will still dump moderate to heavy rains that may cause floods and landslides in northern and Central Luzon starting Monday night, said PAGASA weather forecaster Benison Estareja.
It may also trigger 3 to 6-meter storm surges in parts of Isabela, he said.
Two to 3-meter waves, meanwhile, may hit the coastal villages in La Union, Pangasinan, and Cagayan, while 1-2 meter storm surges are possible in parts of Ilocos Norte and Ilocos Sur, he added.
Residents in these areas should stay away from the beach, cancel all marine activities and evacuate to higher ground, said Estareja.
The weather agency raised storm signal 3 over Isabela, Quirino, and northern Aurora, which may be whipped by up to 170 kph winds in the next 18 hours.
The following areas, which could experience up to 120 kph winds, were placed under signal 2.
- Ilocos Sur
- Mountain Province
- La Union
- Nueva Vizcaya
- Nueva Ecija
- Northern Quezon
- Polillo Island
- Southern Aurora
Signal 1, meanwhile, was up in these areas:
- Southern Quezon
- Ilocos Norte
- Batanes and Babuyan group of Islands
- Metro Manila
- Camarines Norte
After making landfall, Rosita will cross northern Luzon, exit the landmass in the La Union-Pangasinan area and leave the Philippine area of responsibility on Wednesday, Estareja said.
The typhoon's outer bands may continue to bring rains until All Souls' Day Thursday, as millions of Filipinos troop to cemeteries to honor their dead, PAGASA earlier said.
Two more storms may hit the country before the year ends, said the weather agency.
Last September, powerful typhoon Ompong (Mangkhut) ripped thorugh northern Luzon, swamping farmlands and unleashing landslides that killed at least 75 people.
