Pagasa update on tropical depression Nika
Between tonight and tomorrow evening, the combined effects of “NIKA” and the Southwest Monsoon will bring moderate to heavy rains over southern Isabela, Quirino, Nueva Vizcaya, Mountain Province, Ifugao, Benguet, La Union, Pangasinan, Central Luzon, Rizal, and northern Quezon including Polillo Islands. Light to moderate with at times heavy rains will also be experienced over Metro Manila and the rest of Luzon.
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.
No tropical cyclone wind signal is in effect. However, the enhancement of both the Southwest Monsoon and the Northeasterly Surface Windflow will bring strong winds with occasional gusts over the northern and western section of Luzon, especially in coastal and mountainous areas.
