TROPICAL DEPRESSION 13W (NONAME) NEWLY-FORMED WEST OF GUAM...ACCELERATING
WEST-NORTHWEST TOWARDS THE PHILIPPINE SEA...SHALL ENTER THE PHILIPPINE

AREA OF RESPONSIBILITY (PAR) TOMORROW.

+ FORECAST OUTLOOK: 13W is expected to maintain its fast WNW track for the

next 2 to 3 days and shall reach Tropical Storm status before entering PAR

tomorrow. The 3 to 5-day long-range forecast shows 13W turning gradually

towards the NW to NNW on Wednesday and Thursday (Aug 20-21) in the direc-

tion of Taiwan-Okinawa area. *Alternate Forecast Scenario: There is a po-
ssibilty 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 Mindoro, Palawan

and Western Visayas.

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!
