2-DAY FORECAST OUTLOOK & ANALYSIS*

TALAS (15W) is expected to swiftly accelerate toward the NNE during the next 24 to 48 hours. On the forecast track, the center of the storm will move across the Sea of Japan throughout the day...and approach the coast of Eastern Russia Monday. TALAS will become an Extratropical Low prior in making landfall over Eastern Russia Monday evening or Tuesday morning. Below is the summary of the 2-day forecast for this system.

MONDAY MORNING:  Just along the northern part of the Sea of Japan...about 290 km SE of Vladivostok, Russia [11AM SEP 05: 41.6N 134.8E @ 85kph].
TUESDAY MORNING:  Becomes an Extratropical Cyclone while moving into Eastern Russia...about 238 km ENE of Vladivostok, Russia [8AM SEP 06: 44.4N 134.3E @ --kph].

Maximum Sustained Winds (10-min. avg) have decreased to near 75 km/hr (40 knots) with higher gusts. TALAS is a Tropical Storm (TS) on the Saffir-Simpson Tropical Cyclone Scale.

TALAS remains a very large-sized tropical cyclone with a diameter of 1,295 kilometers (700 nautical miles).

*Please be reminded that the 2-Day Forecast Outlook changes every 6 hours, and 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 must be anticipated from time to time.


EFFECTS & HAZARDS SUMMARY

TALAS' (15W) large circulation remains fragmented as it moves into the Sea of Japan. Below is the summary of the storm's parts and its hazards affecting specific areas:

FRAGMENTED INNER RAINBANDS - affecting & spreading across the coastal areas of the Northern & Northwestern parts of Honshu. Tropical Storm Conditions w/ Tropical Storm Force Winds (62-117 kph) will be expected along these bands.
OUTER RAINBANDS - affecting & spreading across the rest of Honshu & the Sea of Japan. Tropical Depression Conditions w/ moderate to strong winds (25-61 kph) will be expected along these bands (click here to know more about Rainbands).
24HR TOTAL RAINFALL ACCUMULATION - from 5 up to 100 mm (low to high rainfall) can be expected along areas affected by the outer & inner rainbands (see above)...with isolated amounts of 105 to 205 mm (high) along areas near the center of TALAS (15W). (click to open NOAA's eTRaP graphic).

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): 8 AM (00 GMT) SUN 04 SEPTEMBER POSITION: 37.0N 134.5E.
*TROPICAL DEPRESSION 15W, LOCATED APPROXIMATELY 200 NM NORTHEAST OF
IWAKUNI, JAPAN, HAS TRACKED JUST EAST OF NORTHWARD AT 13 KNOTS OVER
THE PAST SIX HOURS. ANIMATED INFRATED SATELLITE IMAGERY INDICATES
CENTRAL CONVECTION HAS SIGNIFICANTLY ERODED AND DISPLACED NORTHEAST-
WARD AS THE SYSTEM BECAME EXPOSED TO VERY STRONG (40-60 KT) VERTICAL
WIND SHEAR ASSOCIATED WITH A MID-LATITUDE TROUGH DIGGING IN FROM THE
NORTHWEST. THE LOW LEVEL CIRCULATION CENTER HAS BECOME DISTORTED AND
DIFFICULT TO PINPOINT. A BROAD AND ELONGATED NOTCH FEATURE ON A
032213Z SSMIS MICROWAVE IMAGE COUPLED WITH A REFLECTIVITY RADAR LOOP
FROM CHOGOKU WERE USED TO APPROXIMATE THE INITIAL POSITION. THE
INITIAL INTENSITY WAS BASED ON NEARBY SURFACE OBSERVATIONS AND
SUPPORTED BY A DVORAK ESTIMATE FROM RJTD. TD 15W IS NOW EMBEDDED
IN THE BAROCLINIC ZONE IN THE COLDER WATERS OF THE SEA OF JAPAN.
IT IS EXPECTED TO BECOME EXTRA-TROPICAL BY TAU 12. THE SYSTEM IS
ALSO EXPECTED TO WEAKEN SIGNIFICANTLY IN VIEW OF THE HARSH
ENVIRONMENTAL CONDITIONS...
