Signal No. 2 has been hoisted in 13 areas in Luzon as Typhoon Uwan maintained its strength and moved northwestward over the West Philippine Sea, PAGASA said late Monday evening.
Based on the state weather bureau's 11 p.m. cyclone bulletin, the following areas are under Signal No. 2:
Signal No. 1 is placed under the following areas:
At 10 p.m., Uwan was located 245 km west northwest of Laoag City, Ilocos Norte or 245 km west northwest of Sinait, Ilocos Sur.
It is carrying maximum sustained winds of 120 km/h near the center and gusts of up to 150 km/h, and was moving northwestward at 15 km/h.
State meteorologists warned that on Tuesday, the storm will bring occasionally gusty conditions reaching strong to gale-force strength over most of Luzon that are not under any wind signal.
Meanwhile, within the next 12 hours, a moderate risk of storm surge with peak heights reaching 1.0 m to 2.0 m is expected over the low-lying or exposed coastal communities of the Ilocos Region.
A gale warning is still in effect over the seaboards of Northern and Central Luzon and the western seaboards of Southern Luzon.
PAGASA maintained that heavy rainfall, severe winds, and storm surge may still be experienced far from the landfall point or center track, and even in areas outside the forecast confidence cone.
Uwan is expected to follow a recurving path turning northward then northeastward on Tuesday for most of the forecast period.
"A brief period of re-intensification may take place tonight until tomorrow while UWAN moves over the waters southwest of Taiwan, before eventually weakening from Wednesday (12 November) onwards," PAGASA said.
It added that Uwan will then exit the Philippine Area of Responsibility (PAR) on Monday evening or early Tuesday morning.
"It may re-enter PAR on Wednesday evening as it makes landfall over the southwestern coast of Taiwan, resulting in further weakening," PAGAS said.
"It will then emerge over the waters near Ryukyu Islands on Thursday (13 November), where it is expected to eventually weaken into a remnant low on Friday (14 November)," it added. -- Mariel Celine Serquiña/RF, GMA Integrated News
