Tropical Depression Wilma is expected to bring heavy rains to areas far beyond its projected landfall zone as its effects combine with the shear line and the Northeast Monsoon, the Philippine Atmospheric, Geophysical and Astronomical Services Administration (PAGASA) warned on Friday, Dec. 5.
“It must be emphasized that heavy rainfall and severe winds may still be experienced in localities outside the landfall point and the forecast confidence cone,” PAGASA’s Tropical Cyclone Bulletin No. 6 noted.
“Furthermore the Northeast Monsoon (Amihan) will also bring strong to gale-force gusts over the following areas not under Wind Signal (especially in coastal and upland areas exposed to winds).”
According to the state weather bureau, Wilma maintained maximum sustained winds of 45 kilometers per hour (kph). moving west-southwest at 15 kph toward Eastern Visayas, where landfall or a close passage is expected between Friday night, Dec. 5,and early Saturday, Dec. 6.
Despite its relatively weak winds, PAGASA emphasized that rainfall may become the more significant hazard.
The state weather bureau urged communities not under Tropical Cyclone Wind Signal (TCWS) No. 1 to remain alert as rains may still develop due to the interaction of Wilma with the shear line and the Northeast Monsoon.
Here are the areas placed under Signal No. 1:
(Luzon)
The southern portion of Sorsogon (Matnog, Bulan, Irosin, Santa Magdalena, Bulusan, Barcelona, Magallanes, Juban, Casiguran, Gubat), and mainland Masbate, including Ticao Island.
