2.C ADDITIONAL INFORMATION:
T=CI=4.5-

THE LAST INFRARED IMAGES SHOW THE PREMISE OF AN ELONGATED EYE
PATTERN. TROPICAL CYCLONE STAGE IS CONFIMED BY THE 2045Z 85GHZ SSMI
MICROWAVE IMAGE THAT SHOWS NOW A CLOSED EYE.

TODAY URIAH'S TRACK SHOULD PROGRESSIVELY BEND SOUTHWESTWARD THEN
SOUTHWARD THURSDAY WITH THE REBUILDING OF A MID-LEVEL RIDGE IN THE
EAST. FRIDAY, URIAH IS LIKELY TO SLOW DOWN BECAUSE OF THE BUILDING OF
A MID LEVEL RIDGE IN THE SOUTH. MODEL GUIDANCE STILL SHOW LARGE
SPREAD FROM FRIDAY EVENING, SUGGESTING AN INCREASED UNCERTAINTY.
HOWEVER, THE MAJORITY OF THE ENSEMBLE MEMBERS AND THE OTHER NWP
MODELS FORECAST A SOUTHWARD TRACK STEERED BY A BAROCLINIC LOW MOVING
TOWARDS THE MID-LATITUDES AND CAUSING A WEAKNESS IN THE SUBTROPICAL
RIDGE.

ON THIS TRACK, UPPER LEVELS CONDITIONS SHOULD REMAIN CONDUCIVE WITH A
WEAK VERTICAL WINDSHEAR. ADDITIONNALY, THE BUILDING OF A NEW OUTFLOW
CHANNEL ON THE POLAR SIDE ALONG WITH GOOD OCEANIC HEAT CONTAIN NEAR
80E, ARE LIKELY TO HELP THE SYSTEM INTENSIFYING MORE RAPIDLY. FROM
THURSDAY, THE ARRIVAL OF AN UPPER TROUGH WILL INCREASE THE
NORTH-WESTERLY VWS, AND START THE WEAKENING, ACCENTUATED BY THE
MARGINAL OCEAN HEAT CONTENT SOUTH OF 23-24S. MOREOVER, THE SLOW
MOTION FORECAST FROM FRIDAY IS EXPECTED TO SIGNIFICANTLY COOL THE
UNDERLYING SST AND INCREASE THE WEAKENING TREND.=

南太的溫士頓上望很高,但疑似受到風切20kt影響. 發展目前不順

南印的Uriah發展正走入正規




目前升到Cat.3
高層開眼 , 結構整齊後. 強度還有上望Cat.4

底層還可以 , 不過OHC比較高區域.已經脫離..

環境開始轉差.



老J給了115kt而已 . 感覺有點低了.  Meteo-7分辨太差. 沒辦法..

烏利亞的巔峰美圖

最後給出了125kts  , 暫時的風王. 估計維持不久(隔壁溫士頓可能超越)
