ANALYSIS & FORECAST OUTLOOK (up to 2 days)*

TY KOMPASU is currently crossing Central Korea and is expected to rapidly accelerate NE to ENE across the eastern part of the Korean Peninsula this morning, and exiting through the Sea of Japan this afternoon. This system is likely to be downgraded into tropical storm soon. The cyclone will begin Extratropical transition later tonight...completing its transition tomorrow [2AM SEP 03: 41.3N 132.4E @ 75kph...2PM SEP 03: 42.3N 137.8E @ 65kph]. KOMPASU will be over the eastern coast of Hokkaido, Japan by early tomorrow morning [2AM SEP 04: 42.0N 143.7E @ 55kph].

KOMPASU is a Category 1 Typhoon on the Saffir-Simpson Scale. Current Maximum Sustained Winds (1-min. avg) are near 130 km/hr (70 kts) with higher gusts. Typhoon Force Winds (120 km/hr or more) extend outward up to 35 kilometers (20 nautical miles) from the center...and Tropical Storm Force Winds (62-117 km/hr) extend outward up to 130 kilometers (70 nautical miles).

EXTENDED FORECAST TRACK (3 days)*

SUNDAY EARLY MORNING:  Over the NW Pacific Ocean [2AM SEP 05: 39.1N 155.6E @ 55kph].

*Please be reminded that the Forecast Outlook changes every 6 hours, and the Extended Forecast Track have an average error of 250 km on Day 3...450 km on Day 4...and 650 km on Day 5, while the wind speed forecast error, averages 35 kph per day. Therefore, a turn to the left or right of its future track and changes in its wind speed can be expected from time to time.

EFFECTS & HAZARDS

KOMPASU's circulation continues to lose tropical characteristics...may start Extratropical transition soon. Typhoon Conditions are continuing across a small area (35 km outward from the center) in Central Korea...Tropical Storm Conditions spreading across most parts of Central Korea...will be reaching Eastern Korea later this morning . Click here to view the latest NOAA-CIRA's Wind Analysis. 6-hr total rainfall amounts of 5 up to 100 mm (light to moderate rain) can be expected along its rainbands...with isolated amounts of up to 150 mm (Moderate) near the center of Kompasu. Click here to view the latest NOAA's eTRaP graphic on the storm's rainfall amount. Under Tropical Storm Conditions, storm surge heights may reach 1 to 3 feet (0.3 to 0.9 meters) above ground level w/ large and dangerous battering waves...increasing to 4 or 5 feet (1.2 or 1.7 meters) during Typhoon Conditions.

Important Note: Please keep in mind that the above forecast outlook, extended forecast, effects-hazards, current monsoon intensity, & tropical cyclone watch changes every 6 to 12 hrs!

JTWC (US NAVY & AIR FORCE) REMARKS:

REMARKS (for Meteorologists): 2 AM (18 GMT) THU 02 SEPTEMBER POSITION: 36.1N 125.5E.
*ANIMATED INFRARED SATELLITE IMAGERY DEPICTS RAPIDLY DECAYING DEEP
CONVECTION SHEARING NORTHEAST OF THE LOW-LEVEL CIRCULATION
CENTER (LLCC). HOWEVER, A 011745Z TRMM 37 GHZ IMAGE CONTINUES
TO INDICATE A STRONG LLCC SIGNATURE WITH A MICROWAVE EYE
FEATURE. THE CURRENT POSITION IS BASED ON THIS IMAGE WITH
HIGH CONFIDENCE. THE CURRENT INTENSITY IS BASED ON THE
HIGHER END OF DVORAK ESTIMATES RANGING FROM 65 TO 77 KNOTS
BUT IS CONSISTENT WITH THE WELL-ORGANIZED LLCC AND IS
SUPPORTED BY SURFACE OBSERVATIONS FROM KUNSAN AND SEOSAN
INDICATING 40 TO 46 KNOTS. THESE OBSERVATIONS ALSO SUPPORT
THE 34- AND 50-KNOT WIND RADII AT TAU 0. MODEL GUIDANCE
REMAINS TIGHTLY-CLUSTERED THEREFORE THERE IS NO CHANGE TO
THE FORECAST TRACK. THE MAJOR CHANGE TO THIS FORECAST IS
THAT THE TIMING OF EXTRA-TROPICAL TRANSITION (ETT) IS EARLIER.
THE SYSTEM IS CURRENTLY MOVING OVER COOLER SST AND INTO
THE MIDLATITUDE WESTERLIES. VERTICAL WIND SHEAR HAS INCREASED
TO 30-40 KNOTS AND IS EXPECTED TO CONTINUE INCREASING. THE
SYSTEM IS INTERACTING WITH A WEAK BAROCLINIC ZONE SITUATED
OVER THE NORTHERN YELLOW SEA. TY 08W IS EXPECTED TO COMPLETE
ETT AND BECOME FULLY EMBEDDED IN THE BAROCLINIC ZONE BY TAU
24 TO 36.
