PAGASA says there remains the possibility of a 2nd landfall for Tropical Depression Vicky, either in the Siquijor-Negros Oriental area or the Misamis Occidental-Zamboanga del Norte area

Tropical Depression Vicky emerged over the Bohol Sea late Friday evening, December 18, exiting land through Misamis Oriental.

Vicky had made landfall in Baganga, Davao Oriental, at 2 pm on Friday. After hitting Davao Oriental, it also crossed Davao de Oro, Agusan del Sur, and Misamis Oriental.

Based on the bulletin released by the Philippine Atmospheric, Geophysical, and Astronomical Services Administration (PAGASA) at 11 pm on Friday, the tropical depression is already 75 kilometers west northwest of El Salvador City, Misamis Oriental, or 75 kilometers east of Dipolog City, Zamboanga.

Vicky accelerated further, now moving west northwest toward the Sulu Sea at 40 kilometers per hour (km/h) from the previous 30 km/h.

PAGASA said there remains the possibility of another landfall, either in the Siquijor-Negros Oriental area or the Misamis Occidental-Zamboanga del Norte area before the tropical depression reaches the Sulu Sea.

Afterwards, Vicky is projected to cross the northern or central part of Palawan between Saturday afternoon and evening, December 19.

While crossing parts of the Philippines, Vicky will likely remain a tropical depression, according to PAGASA. So far, it continues to have maximum sustained winds of 45 km/h, while its gustiness is up to 70 km/h. (READ: FAST FACTS: Tropical cyclones, rainfall advisories)

But once Vicky has crossed Palawan and is already over the West Philippine Sea, “the likelihood of intensification is forecast to increase,” said the state weather bureau.

Below is PAGASA’s updated rainfall forecast for Vicky and the tail-end of a frontal system or shear line. It stressed that more floods and landslides may occur, as the rain could be intense.

PAGASA said areas under Signal No. 1 will have “strong breeze to near gale conditions.” But it noted that gusty conditions are also likely in most parts of Luzon and the Visayas which are not under Signal No. 1, due to the surge of the northeast monsoon or hanging amihan. Coastal and mountainous areas, most especially, would be affected.

Vicky and the surge of the northeast monsoon will continue to affect coastal waters in the next 24 hours as well. Travel remains risky.
