22W (UNNAMED) moving rapidly to the west...now a Tropical Storm...will pass south of Guam this morning.

*Residents and visitors along Eastern Luzon and the Mariana Island Chain should closely monitor the progress of 22W.

*Kindly refer to your local warnings & bulletins issued by your country's official weather agency. This advisory is intended for additional information purposes only.

+ Forecast Outlook: 22W is expected to start decelerating as it turns WNW-ward within the next 12 to 24 hours. The 2 to 5-day Long-Range Forecast shows 22W entering the Philippine Area of Responsibility (PAR) Saturday morning Oct 17 as a Category 1 Typhoon...turning more westerly slowly towards Eastern Luzon on Sunday Oct 18. It shall rapidly grow into a Category 3 Typhoon on Tuesday Oct 20 in a track that could bring it to Northern Luzon on Wednesday or Thursday. *ECMWF 10-Day Extended Long-Range Forecast: 22W shall make landfall over Northern Luzon or over Isabela Wednesday evening, Oct 21 and exit thru Ilocos Sur early Thursday morning, Oct 22. It shall be approaching Hainan Island on Saturday evening Oct 24. Please be reminded that the ECMWF model run changes every 12 hours, so a shift to the left or right of its future track and other conditions must be considered.

+ Effects: 22W's broad circulation continues to consolidate while moving rapidly westward. Its outer bands now spreading into Southern Marianas - bringing occasional rains w/ squalls and thunderstorms. 1-day rainfall accumulations of 50 up to 100 mm (moderate to heavy rain) can be expected along PARMA's rainbands...with isolated accumulations of up to 200 mm (very heavy rain) near the center of 22W particularly along its projected path. Residents in low-lying areas & steep slopes must remain alert & seek evacuation for possible life-threatening flash floods, mudslides & landslides due to the anticipated heavy rains brought about by this system. Precautionary measures must be initiated if necessary.

+ Tropical Cyclone Watch:

(1) Tropical Disturbance 93W (LPA) has moved out into the South China Sea...its rainbands spreading across Metro Manila, Mindoro, Southern Tagalog Provinces, Central Luzon and Northern Palawan including Calamian Island Group...currently located near lat 12.8N lon 118.5E...or about 205 km WNW of Coron, Palawan...with 1-min maximum sustained winds of 30 kph near the center...moving WNW @ 26 kph towards Vietnam. This system may likely become a Tropical Cyclone while over the South China Sea.
