A low pressure area off Catanduanes has developed into a tropical depression and was named “Jolina.”
Storm Signal No. 1 was raised over southern Cagayan, Isabela and northern Aurora, the Philippine Atmospheric, Geophysical and Astronomical Services Administration (Pagasa) said.
Possible storm Signal No. 1 could be raised over Quirino, Ifugao, Mt. Province, Kalinga and Northern Cagayan, it added.
Moderate to heavy rains are expected within the 300 kilometer diameter of Jolina.
The tropical depression is seen to grow stronger before it makes landfall over northern Luzon by Friday evening or early Saturday morning.
Jolina was last spotted 540 kilometers east of Casiguran, Aurora, with maximum sustained winds of 45 kilometers per hour near the center and gusts of up to 60 kph.
It moved west northwest at 17 kph.
