TROPICAL DEPRESSION 13W (NONAME) NEARS TROPICAL STORM STRENGTH...CENTER

RELOCATED FARTHER TO THE WEST-NORTHWEST...SHALL ENTER THE PHILIPPINE

AREA OF RESPONSIBILITY (PAR) TOMORROW.

+ FORECAST OUTLOOK: 13W is expected to resume its WNW track for the next

2 to 3 days across the Philippine Sea and shall reach Tropical Storm sta-

tus before entering PAR late tonight. The 3 to 5-day long-range forecast

shows 13W becoming a Typhoon and turning gradually towards the NW to NNW

on Wednesday and Thursday (Aug 20-21) in the direction of Taiwan. It shall

be approaching the Eastern Coast of Taiwan on Friday afternoon, Aug 22.

*Alternate Forecast Scenario: There is a possibilty that 13W may continue

moving WNW passing over Northern Luzon-Batanes Area, if the High Pressure

Steering Ridge to its North remains strong and extends westward.

+ EFFECTS: 13W's developing circulation and spiral bands remains at sea

and is not affecting any Pacific Islands at this time. Once this system

reaches the Philippine Sea, it may enhance the Southwest (SW) Monsoon

and bring widespread rains across the Philippines next week.

+ CURRENT MONSOON TROUGH (ITCZ) INTENSITY: Strong ITCZ (aka. Monsoon Trough)

& Southwest Windflow affecting the Philippines. It will continue to bring

widespread scattered rains and thunderstorms - most especially in the

afternoon or evening becoming more frequent across Palawan.

Important Note: Please keep in mind that the above forecast outlook,
effects & current monsoon intensity, and tropical cyclone watch changes
every 06 to 12 hours!
