MANILA - (2nd UPDATE) More areas were placed under signal number 1 early Tuesday as tropical storm Ulysses slowed down while approaching Quezon, the state weather bureau said.
The country's 21st storm this year is forecast to strengthen into a severe tropical storm by Tuesday night and may reach typhoon category and its peak intensity on Wednesday afternoon or evening, PAGASA said.
Ulysses was last estimated 475 kilometers east of Virac, Catanduanes as of 10 a.m., moving northwest at 15 km per hour while slightly stronger winds of 75 kph near the center and gusts of up to 90 kph, according to the weather bureau.
It is expected to "closely approach" Catanduanes and Camarines Norte on Wednesday and is forecast to make landfall over Quezon on Thursday morning, PAGASA said.
A "slight southward shift" in its track shows an "increasing likelihood of landfall" over Bicol region between Wednesday afternoon or evening, it added.
Ulysses may traverse south of Metro Manila between Thursday morning and afternoon, said PAGASA weather specialist Chris Perez.
"Mula po Central Luzon, southern Luzon, kasama ang Metro Manila at ibang bahagi ng Visayas ay kailangan pong maghanda sa posibleng direct effect ng Ulysses," he told ABS-CBN's Teleradyo.
(From Central Luzon, southern Luzon, including Metro Manila and parts of Visayas needs to prepare for Ulysses' possible direct effect.)
The storm comes as majority of southern Luzon is still reeling from the onslaught of Super Typhoon Rolly and Typhoon Quinta, which left billions of pesos in damage and killed dozens.
On Tuesday, it will bring light to moderate with at times heavy rains over Aurora, Quezon, Bicol Region, Eastern and Central Visayas, Caraga, Zamboanga Peninsula, Basilan, Sulu, Tawi-Tawi.
Moderate to heavy rains associated with the rainbands of "Ulysses" will begin affecting Bicol region and portions of Eastern Visayas on Wednesday, PAGASA said.
The tail-end of a cold front on Tuesday would bring light to moderate with at times heavy rains over Cagayan including Babuyan Islands, Isabela, and Apayao.
PAGASA warned that flooding, rain-induced landslides, and sediment-laden streamflows (e.g. lahar) may occur during heavy or prolonged rainfall especially in areas that are highly susceptible to these hazards.
