Severe Tropical Storm Hanna has maintained its strength and is forecasted to develop into a typhoon, the Philippine Atmospheric, Geophysical and Astronomical Services Administration (PAGASA) said on Friday, September 1.
In its 5 AM bulletin, PAGASA said Hanna was located 870 kilometers (km) East of Extreme Northern Luzon, packing 110 km per hour (kph) winds near the center and gusts of up to 135 kph.
The severe tropical storm is progressing west northwestward at 20 kph speed and may continue to head in this direction.
"On the track forecast, the tropical cyclone is forecast to pass close or make landfall in the vicinity of Yaeyama Islands in the Ryukyu archipelago between tomorrow morning and afternoon, then make landfall or pass close to the northern portion of Taiwan tomorrow evening or on Sunday morning," the state weather bureau said.
PAGASA said Hanna may leave the Philippine Area of Responsibility (PAR) on Sunday, September 3.
"Outside the PAR, the tropical cyclone will turn more northwestward as it passes over the Taiwan Strait before making another landfall over mainland China on Sunday afternoon or evening," it said.
At this time, PAGASA has not hoisted any Tropical Wind Signal (TCWS) due to Hanna.
The state weather bureau said the combined forces of Hanna, Typhoon Saola, formerly known as Goring, and Severe Tropical Storm Kirogi will enhance the southwest monsoon, and bring occasional to monsoon rains over the western portion of Luzon.
