TROPICAL STORM HAGUPIT (NINA) ALMOST A TYPHOON AS IT CONTINUES TO
TRACK NORTHWESTWARD...CLOSER TO EXTREME NORTHERN LUZON...OUTER RAIN
BANDS AFFECTING THE EASTERN COAST OF LUZON.

*Residents along Isabela, Cagayan, Batanes-Babuyan-Calayan Islands & Taiwan should closely monitor
the progress of HAGUPIT (NINA).


+ FORECAST OUTLOOK: HAGUPIT is expected to turn WNW tomorrow morning...
becoming a Category 1 Typhoon tonight. The 2 to 5-day long-range forecast
shows HAGUPIT, passing over or very close to Batanes Island tomorrow eve-
ning. It shall then move out into the South China Sea on Tuesday, Sep 23.
The typhoon shall be approaching the southern coast of Guangdong Province
of China, near Hong Kong-Macau area on Wednesday morning Sep 24...making
landfall just west of Macau Wednesday afternoon. HAGUPIT shall dissipate
along Northern Vietnam on Friday afternoon, Sep 26.

+ EFFECTS: HAGUPIT's large circulation remains over the Philippine Sea,
with the appearance of the eye as of this moment. Its outer bands conti-
nues to affect the Bicol Region, Samar Provinces and across the Eastern
Coast of Luzon. Under these bands, the affected areas will experience
light to moderate rainfall w/ winds not exceeding 50 km/hr. Moderate to
heavy Squalls associated with the outer bands can be expected along the
affected areas. Deteriorating weather conditions can be expected early
tomorrow morning across Extreme Northern Luzon, as the inner rainbands
approaches. Residents in low-lying areas & steep slopes must remain alert
& seek evacuation for possible life-threatening flash floods & landslides
due to the anticipated heavy rains brought about by this system. Precau-
tionary measures must be initiated if necessary. Possible coastal Storm
Surge flooding of 4 to 5 feet above normal tide levels...along with large
and dangerous battering waves can be expected near and to the east of
HAGUPIT's projected path particularly on where the center passes by across
Extreme Northern Luzon. Minimal damage is possible on this type of storm
surge.

+ CURRENT MONSOON INTENSITY: The
surge of the Southwest (SW) Monsoon
which has been enhanced by TS HAGUPIT (NINA) continues to affect Metro
Manila, Western Luzon, Visayas including Palawan & Mindoro. 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!
