"SIONY" SLIGHTLY INTENSIFIES AS IT MOVES SLOWLY OVER THE PHILIPPINE SEA EAST OF EXTREME NORTHERN LUZON.
Track and intensity outlook:
Track: "SIONY" is forecast to move slowly or almost stationary in the next 24 hours. Afterwards, the tropical storm will move generally westward towards Extreme Northern Luzon. A landfall scenario over Batanes-Babuyan Islands area around Friday remains likely. However, due to the projected quasi-stationary state of this tropical storm, there remains a high degree of uncertainty in the forecast track.
Intensity: "SIONY" is forecast to intensify into severe tropical storm in the next 24 to 36 hours. Intensification into Typhoon is likely on Thursday prior to close approach or landfall over Extreme Northern Luzon.
Hazards affecting land areas:
Today, the combined effects of the northeasterlies and the trough of Tropical Storm "SIONY" will bring light to moderate with at times heavy rains over Batanes, Apayao, Cagayan, and Isabela. Flooding (including flashfloods) and rain-induced landslides may occur during heavy or prolonged rainfall especially in areas that are highly or very highly susceptible to these hazards. PAGASA Regional Services Divisions may issue local thunderstorm/rainfall advisories and heavy rainfall warnings as appropriate.
The northeasterlies enhanced by Tropical Storms "ROLLY" and "SIONY" will bring strong to near gale conditions with higher gusts over Batanes, Babuyan Islands, and the northern portions of Cagayan and Ilocos Norte.
