Name: TROPICAL DEPRESSION 18W [NINA]

TROPICAL DEPRESSION 18W (NINA) NEWLY-FORMED WEST OF GUAM, IS ABOUT TO
ENTER THE PHILIPPINE AREA
OF RESPONSIBILITY (PAR) AS IT ACCELERATES
WEST-SOUTHWESTWARD DURING
THE PAST SIX HOURS.

*Residents along the East Coast of Luzon including the Bicol Region should closely monitor the
progress of 18W (NINA).


+ FORECAST OUTLOOK: 18W is expected to slow down and turn westward for
the next 24 hours. It shall become a Tropical Storm later this afternoon
or evening. The 3 to 5-day long-range forecast shows 18W turning WNW-ward
in the direction of Batanes-Taiwan Area, becoming a Categoy 3 Typhoon w/
projected winds of almost 200 kph by Wednesday morning, Sep 24. *Alter-
nate Forecast Scenario: There's a possibilty that 18W may track more
Westward, making landfall over Central or Northern Luzon on Wednesday.
This scenario is likely if the westward extension of the strong steering
ridge north of 18W remains strong.

+ EFFECTS: 18W's developing circulation remains over the eastern part of
the Philippine Sea and is not yet affeting any Pacific Islands.

+ CURRENT MONSOON INTENSITY
A surge of the Southwest (SW) Monsoon has
been enhanced by the developing TD 18W (PRE-NINA) across Palau, Ulithi,
Yap and other small islands of Western Micronesia. This wind system is
expected to bring mostly cloudy skies with possible "on-&-off" light to
moderate to sometimes heavy rains & winds not exceeding 40 km/hr
.

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!
