(UPDATED) MANILA—Tropical Storm "Salome" maintained its strength and is now off the coast of Zambales and Bataan, state weather bureau PAGASA said in its morning advisory on Friday.

Salome was upgraded from a tropical depression to a tropical storm Thursday night, putting Metro Manila and neighboring provinces under signal no. 2.

But in PAGASA's 5 a.m. bulletin, only Bataan and southern Zambales were under signal no. 2.

The public storm warning was lowered to signal no. 1 in Metro Manila, Bulacan, Pampanga, Cavite, Batangas, the rest of Zambales, and northern Occidental Mindoro.

PAGASA warned residents in these areas, as well as those living in Central Luzon and CALABARZON, of possible flash floods and landslides, as Salome is expected to bring moderate to heavy rains.

Meanwhile, heavy rains battered Metro Manila overnight, particularly in Quezon City.

Waist-high waters were reported in Barangay Kamuning, where boats were prepared by village officials in case the waters rose further.

The center of the tropical storm was last spotted at 55 kilometers southwest of Subic, Zambales. It was packing maximum sustained winds of 65 kilometers per hour near the center and gusts of up to 100 kph.

Salome was moving west northwest at 20 kph. It is expected to exit the Philippine area of responsibility Saturday morning.

In Batangas, nine areas were plunged into darkness in the wee hours of Friday after Salome struck the province.

The Provincial Disaster Risk Reduction and Management Office said a power outage was experienced in Tanauan, Rosario, San Juan, Lobo, San Jose, Cuenca, Mataas Na Kahoy, San Luis, and Nasugbu.

In Batangas City, water levels in the Calumpang river reached the first alarm, prompting officials to prepare residents to evacuate should the situation worsen. — With a report from Arra Perez
