Tropical Weather Discussion for the Western North Pacific between
the Equator and 25N from 130E to 180. The following information is
based on recent satellite imagery/data, weather observations, radar,
and meteorological analysis.

...SPECIAL FEATURES...

TROPICAL CYCLONES...
Typhoon In-fa is located near 22.9N 144.0E this morning and has
weakened since yesterday, now with sustained winds around 115 miles
per hour. Further weakening is anticipated through tonight as dry
air entrainment continues. In-fa is expected to slowly move eastward
today before performing a loop tonight and then moving to the west
with little change in forward speed through Monday. Typhoon force
winds extend outward from the center up to 80 miles. Tropical storm
force winds extend outward from the center up to 165 miles. Maximum
wave heights are 40 feet.

For more information on Typhoon In-fa please refer to the Tropical
Cyclone Public Advisory, prepared by the National Weather Service,
under WMO header WTPQ31 PGUM, or the Tropical Cyclone Warning,
prepared by the Joint Typhoon Warning Center under WMO header WTPN31
PGTW.

...OTHER WEATHER SYSTEMS...

MONSOON TROUGH...
The monsoon-like trough enters the Area of Responsibility near
11N130E and extends east-northeast, passing north of Palau, before
turning to the north-northeast and connecting with Typhoon In-fa. The
trough then dives to the southwest, passing over the far northern
Marianas and continues to the southwest, crossing 10N around 160E
where it turns more west-southwest and passes through the RMI before
exiting the area around 8N180. Convection remains spotty along the
trough but an area of active convection south of the trough axis is
observed from just southeast of Chuuk, passing south of Pohnpei and
ending just south of Kosrae. Scattered to numerous showers and
isolated thunderstorms are observed in this area. The monsoon trough
will sag southward a little over the next day or two with the
aforementioned convection south of the trough axis washing out but
another area developing south of Majuro may lift northward.

OTHER SYSTEMS...
A trade-wind surge is located from roughly 165E to the Dateline
where it continues to extend eastward and from 15N to well past 25N.
Yesterday evening`s ASCAT pass showed winds ranging from 20 to 25
knots with pockets of up to 30 knots near the Dateline. Isolated to
low-end scattered showers are seen accompanying this surge with
partly to locally mostly cloudy sky cover. This surge will push
westward over the next couple of days.
