2-DAY FORECAST OUTLOOK & ANALYSIS*

TALAS (15W) is expected to accelerate toward the North during the next 24 hours, with a slight turn towards the NNE through 48 hours. On the forecast track, the center of the storm will move across Western Honshu through the night...and move out into the Sea of Japan early tomorrow morning. TALAS will be moving into the central part of the Sea of Japan Sunday afternoon...and over Eastern Russia Monday afternoon. Below is the summary of the 2-day forecast for this system.

SUNDAY AFTERNOON:  Moving North across the Sea of Japan...about 478 km North of Okayama, Japan [5PM SEP 04: 39.0N 133.8E @ 95kph].
MONDAY AFTERNOON:  Becomes an Extratropical Cyclone while moving into Eastern Russia [2PM SEP 05: 45.1N 135.7E @ --kph].

Maximum Sustained Winds (10-min. avg) remain near 100 km/hr (55 knots) with higher gusts. TALAS is a Tropical Storm (TS) on the Saffir-Simpson Tropical Cyclone Scale. TALAS will weaken upon crossing Western Honshu later tonight.

Tropical Storm Force Winds (62-117 km/hr) extend outward up to 220 kilometers (120 nautical miles) from the center. TALAS remains a very large-sized tropical cyclone with a diameter of 1,205 kilometers (650 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 radial circulation remains fragmented as it crosses Western Honshu. Below is the summary of the storm's parts and its hazards affecting specific areas:

LARGE EYE-LIKE CENTER - Over Western Honshu, Japan. Possible calm and lull conditions (with <20 kph winds) will be expected inside the eye (click here to know more about the EYE).
FRAGMENTED INNER RAINBANDS - affecting & spreading across Shikoku, Eastern Kyushu & Western Honshu. Tropical Storm to Near-Typhoon Conditions w/ Tropical Storm to Near-Typhoon Force Winds (62-117 kph) will be expected along these bands.
OUTER RAINBANDS - affecting & spreading across the whole of Japan & the Sea of Japan except Northern Honshu. 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 210 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): 2 PM (06 GMT) SAT 03 SEPTEMBER POSITION: 34.2N 133.8E.
*TROPICAL STORM 15W (TALAS), LOCATED APPROXIMATELY 80 NM EAST OF
IWAKUNI, JAPAN, HAS TRACKED NORTHWARD AT 06 KNOTS OVER THE PAST SIX
HOURS. ANIMATED MULTISPECTRAL SATELLITE IMAGERY (MSI) AND RADAR FROM
JAPAN SHOW A WEAKENING LOW LEVEL CIRCULATION CENTER CURRENTLY
TRACKING OVER SHIKOKU. THE INITIAL POSITION IS BASED ON THE MSI AND
A 03/06Z RADAR FIX FROM JAPAN. THE INITIAL INTENSITY IS BASED ON
03/06Z OBSERVATIONS FROM RJOP AND RJOT STATIONS NEAR THE CENTER
REPORTING 987 MB. TS 15W IS EXPECTED TO CONTINUE TRACKING NORTHWARD
ACROSS HONSHU ALONG THE WESTERN PERIPHERY OF A MID-LEVEL SUBTROPICAL
STEERING RIDGE. A MID-LATITUDE TROUGH CURRENTLY TO THE NORTHWEST IS
EXPECTED TO WEAKEN THE STEERING RIDGE AND ALLOW TS 15W TO TURN
NORTHEASTWARD. TS 15W SHOULD BEGIN INTERACTING WITH THE BAROCLINIC
ZONE AFTER ENTERING THE SEA OF JAPAN (SOJ) AND FULLY TRANSITION INTO
AN EXTRA-TROPICAL LOW BY TAU 36. THE SYSTEM WILL CONTINUE WEAKENING
DUE TO LAND INTERACTION AS WELL AS INCREASED VERTICAL WIND SHEAR AND
LOW SEA SURFACE TEMPERATURES IN THE SOJ. THIS FORECAST FAVORS A
STRONGER RECURVATURE SCENARIO INTO THE MID-LATITUDE WESTERLIES THAN
THE NUMERICAL MODELS ARE PREDICTING...
