Tropical Storm CHAN-HOM (02W/Pre-EMONG) now carrying winds of 100 km/hr...still drifting NNE across the South China Sea...may become a Typhoon tonight. Pangasinan, Zambales down to Metro Manila are likely to be the Areas of Projected Impact, as shown on various Numerical Computer Forecast Models.

CHAN-HOM is expected to move slowly NNE to NE-ward for the next 24 hours becoming a Category 1 Typhoon tonight. It shall enter the western part of the Philippine Area of Responsibility (PAR) on early Thursday morning May 7 as a 150-km/hr Typhoon.

The 2 to 5-day Long-Range Forecast shows CHAN-HOM turning more to the ENE and accelerating closer to the coast of Western Luzon. CHAN-HOM shall make landfall either over Pangasinan, Zambales or Metro Manila in Western Luzon sometime Friday morning or afternoon, May 8.
