SUPER TYPHOON YAGI (16W) STRENGTHENED TO A 260-KM/HR
CATEGORY FIVE CYCLONE...MOVING CLOSER TO IWO JIMA-BONIN
ISLANDS...OUTER BANDS NOW OVER THE AREA
.

+ FORECAST OUTLOOK: YAGI is expected to continue moving
WNW to NW'ly for the next 24 hours, with the eye & core
(eyewall) passing very close to Iwo Jima Island tonight
approx 7 PM Japan Standard Time (JST). The 2 to 4-day
(Sep 24-26) Long Range Forecast shows the system doing
a sharp Northward turn & recurving to the NE - sparing
Kyushu, Japan on a direct hit. This dangerous super ty-
phoon is forecast to move into an environment of increa-
sing wind shear and lower sea surface temperatures (SSTs),
thus, gradual weakening can be expected and eventually
losing tropical characteristics sometime Monday (Sep 25)
- becoming an Extratropical Cyclone.
All interests in Iwo
Jima & Southeastern Japan especially Honshu should con-
tinue closely monitoring the progress of this approa-
ching super typhoon
. 

+ EFFECTS: The typhoon's western outer bands has arrived
over Iwo Jima & Bonin Islands. These islands must expect
deteriotating weather conditions later today as the Inner
Bands and its core approaches. Dangerous storm tides with
large battering waves can be expected along the coastal
areas of Iwo Jima & Bonin Islands & Kyushu, Japan today
until Sunday (Sep 24)...Coastal Storm Surge flooding of
greater than than 18 feet is most likely to occur near
YAGI's core
.

+ TROPICAL CYCLONE WATCH: The Tropical Disturbance (LPA/
96W/1006 mb) over the South China Sea now intensifying.
Its ill-defined center was located about 650 km WSW of
Manila (13.8N 115.0E)...drifting West during the past 6
hours w/ winds of 35 km/hr. This system will be closely
monitored for possible development into a Tropical De-
pression within a day or two.


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!
