The Philippine Atmospheric Geophysical and Astronomical Services Administration also said Gener slowed down and continues to be a threat to extreme northern Luzon.
“Bumagal siya dahil sa high-pressure area sa ibabaw ni Gener,” PAGASA forecaster Jori Loiz said in an interview on dzBB radio.
In its 5 p.m. advisory, PAGASA said Gener may bring an estimated 10 to 20 mm per hour of rainfall (heavy to intense) within its 700-km diameter.
Heavy rains since Sunday prompted education and local officials to suspend classes in Metro Manila and nearby provinces. On Monday afternoon, Malacañang announced that work in government offices as well as college level classes were also suspended.
Location of Gener
The weather bureau said that as of 4 p.m., Gener was estimated at 260 km east of Basco, Batanes, packing maximum sustained winds of 120 kph near the center and gustiness of up to 150 kph.
It said Gener was moving north northwest at 7 kph and is forecast to be 210 km northeast of Basco, Batanes Tuesday afternoon. By Wednesday afternoon, it is expected to be 350 km north of Basco, Batanes.
By Thursday afternoon, it is expected to be 600 km north northwest of Basco Batanes, outside the Philippine area of responsibility (PAR).
Storm Signal No. 3 was placed over the Batanes Group of Islands, while Storm Signal No. 2 was placed over Cagayan, Calayan Group of Islands, and Babuyan Group of Islands.
Under Storm Signal No. 1 are Isabela, Kalinga, and Apayao.
PAGASA said Gener may enhance the southwest monsoon that will bring rain and moderate to strong winds over Luzon and Visayas, especially the western section.
It reminded residents in low-lying and mountainous areas to be alert against possible flash floods and landslides. Those living in coastal areas under Storm Signal 2, meanwhile, were advised to remain alert against big waves or storm surges.
Meanwhile, PAGASA reminded fishing boats and other small seacraft not to venture out into the seaboards of Central and Southern Luzon, Visayas, and the eastern seaboard of Mindanao due to the combined effect of Gener and the southwest monsoon. — RSJ, GMA News
