TROPICAL STORM 09W (IGME) NEWLY-FORMED OVER THE NORTHERN PHILIPPINE
SEA
...MOVING SLOWLY WESTWARD...THREATENS EXTREME NORTHERN LUZON AND
TAIWAN.

+ FORECAST OUTLOOK: 09W is expected to continue moving Westward for
the next 2 days as it intensifies. The 3 to 5-day long-rang forecast
shows the system becoming a 120-kph Typhoon (Category 1) as it turns
WNW to NW-ward, passing to the north of Batanes Group of Islands on
Monday morning (July 28) and making landfall over SE Taiwan late Mon-
day afternoon, crossing the Central Taiwan in the evening and moving
out into Taiwan Strait on Tuesday morning, July 29. 09W shall make
landfall anew over Southeastern China Tuesday evening (July 29).
Complete dissipation of 09W is forecast over Fujian Province, China
on Wednesday, July 30. *Alternate Forecast Scenario: There is a po-
ssibilty that 09W may track NW to NNW-ward and pass close to Nor-
thern Taiwan or over Yaeyama Island Chain, if the High Pressure
Steering Ridge to its North weakens or retreats.  

+ EFFECTS: 09W's main circulation continues to organize over the Nor-
thern Philippine Sea, with improving spiral bands on the Northern and
Northwestern portion of the system. This storm is not yet affecting
any land mass.

+ CURRENT MONSOON INTENSITY: The Southwest (SW) Monsoon may be re-
activated once again by TS 09W (IGME) this weekend, and shall affect
Southern Luzon, Bicol Region, Metro Manila, Western Visayas and Wes-
tern Luzon. Partly Cloudy to Cloudy skies with possible light to mo-
derate passing rains w/ at times heavy downpour & SW'ly winds not
exceeding 40 km/hr can be expected. Landslides, mudflows (lahars)
and flooding is likely to occur along steep mountain/volcano slopes,
river banks, low-lying & flood-prone areas of the affected areas.
Strong ITCZ (aka. Monsoon Trough) affecting the rest of the Phili-
ppines bringing scattered rains and thunderstorms - most especially
in the afternoon or evening.

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!

^ANIMATED MULTISPECTRAL IMAGERY DEPICTS A LARGE, APPROXI-
MATELY 600 NM DIAMETER CIRCULATION (MONSOON DEPRESSION) WITH
A SLOWLY CONSOLIDATING SYSTEM EMBEDDED WITHIN THE SOUTHWEST
QUADRANT. A 242115Z QUIKSCAT IMAGE REFLECTS THIS WELL WITH A
BROAD LLCC CENTERED NEAR 21.6N 131.6E, THAT CORRESPONDS WITH
THE CENTROID OBSERVED IN SATELLITE IMAGERY, AND UNFLAGGED 35-
40 KNOT WINDS NEAR THE CENTER. IMAGERY ALSO SHOWS A SMALL,
EXPOSED LLCC NEAR 22.4N 132.1E, NORTHEAST OF THE SYSTEM
CENTER, WHICH IS ROTATING CYCLONICALLY AROUND THE CENTROID.
OVERALL, SYSTEM ORGANIZATION HAS SLOWLY IMPROVED WITH CURVED
CONVECTIVE BANDING EVIDENT IN A 242008Z TRMM IMAGE. THE
SYSTEM HAS BEEN UPGRADED TO TROPICAL STORM STRENGTH BASED
ON DVORAK ESTIMATES OF 35 KNOTS AND THE QUIKSCAT WINDS.
TROPICAL STORM (TS) 09W HAS TRACKED SLOWLY WEST-SOUTHWESTWARD
OVER THE PAST 12 HOURS WITHIN A WEAK STEERING ENVIRONMENT.
THE AVAILABLE MODELS REMAIN IN FAIR AGREEMENT AND ARE CONSIST-
ENT WITH PREVIOUS RUNS
