TD Mirasol made landfall in Casiguran, Aurora at 3:20 a.m. Wednesday, the state weather bureau reported.
Chenel Dominguez, weather specialist of PAGASA, said that Mirasol was carrying maximum sustained winds of 55 kilometers per hour near the center and gustiness of up to 90 kilometers per hour.
It is moving northwest at 10 kilometers per hour, crossing Northern Luzon throughout the day.
“We can see that Mirasol remains under the Tropical Depression category and is now over land in Casiguran, Aurora,” Dominguez said.
“Because it is within land, we observed a slight strengthening in its gustiness,” she added.
Tropical Cyclone Wind Signal No. 1 is up over Batanes, Cagayan including Babuyan Islands, Isabela, Quirino, Nueva Vizcaya, northern and central Aurora, Apayao, Abra, Kalinga, Mountain Province, Ifugao, northern and eastern Benguet, Ilocos Norte, Ilocos Sur, and Polillo Islands.
Strong winds in these areas, she said, are expected along with heavy rainfall brought by Mirasol.
Rainfall exceeding 200 millimeters was already recorded in Aurora, while 100 to 200 millimeters are forecast in Quirino, Isabela, and Cagayan. Parts of the Cordillera Administrative Region, Nueva Vizcaya, Nueva Ecija, and Ilocos Norte may also receive 50 to 100 millimeters of rain.
Dominguez said residents should remain alert for flooding and landslides, especially in areas under rainfall advisories.
The southwest monsoon is also being enhanced by Mirasol, bringing rains over Southern Luzon, western Visayas, and Mindanao.
PAGASA said fair weather is expected in other areas but warned of hot and humid conditions with chances of localized thunderstorms in the afternoon and evening.
A low pressure area (LPA) spotted outside the Philippine Area of Responsibility, about 1,320 kilometers east of southeastern Luzon, may also develop into a tropical cyclone in the coming days, raising the possibility of another storm next week.
Mirasol may intensify into a tropical storm before leaving the Philippine Area of Responsibility by Thursday, PAGASA said.
