MANILA -- Tropical storm "Domeng" is expected to hit landfall over Surigao provinces on Thursday, state weather bureau PAGASA said.
In its 11 a.m. bulletin on Monday, PAGASA said Domeng was last spotted 770 kilometers east of Davao City.
It maintained its strength, still packing maximum sustained winds of 65 kilometers per hour (kph) and gustiness of up to 80 kph.
The storm was still moving in a west northwest direction at 15 kph.
In a press briefing, Renito Paciente, officer-in-charge of PAGASA's weather forecasting division, said that with Domeng's current track and speed, it is expected to make landfall over Surigao del Sur on Thursday morning.
It will then cross northeastern Mindanao, southern Cebu and Negros provinces before crossing northern Palawan on its way to the Sulu Sea on Friday, he said.
No storm signals have been raised by PAGASA yet, but the weather bureau said rains may be felt over eastern Mindanao by Monday afternoon or evening and eastern Visayas by tomorrow.
According to Paciente, the storm has a low chance of intensifying further.
It was also expected to weaken after making landfall on Thursday.
"However, rains will continue over Visayas and Mindanao which may trigger flashfloods and landslides, particularly in the provinces of Surigao, Compostela Valley, Leyte, Bohol and Cebu," Paciente said.
An estimated rainfall of 5 to 15 millimeters per hour (moderate to heavy) was expected within the storm's 400-kilometer diameter.
Local disaster agencies were advised to brace for Domeng's onslaught. Residents in flood-prone areas were also advised to be prepared for possible evacuation.
Paciente said Domeng will have no direct effect on Metro Manila.
Meanwhile, PAGASA hopes the rains will replenish the country's water reservoirs to sustain water supply for power generation and irrigation.
Some water reservoirs, including the Angat, Binga, San Roque and Pantabangan dams, are going down at an average 20 centimeters per day.
PAGASA said supply for irrigation may stop next month if the drop in water levels continues.
