    Ciclone Tropicale Thomas


    Satellite







    REMARKS:
    151500Z POSITION NEAR 16.9S 179.7W.
    TROPICAL CYCLONE (TC) 19P (TOMAS), LOCATED APPROXIMATELY 170 NM
    EAST-NORTHEAST OF NADI, FIJI, HAS TRACKED SOUTHWARD AT 05 KNOTS OVER
    THE PAST SIX HOURS. ANIMATED INFRARED SATELLITE IMAGERY SHOWS
    CONVECTIVE BANDING WRAPPING INTO A LOW LEVEL CIRCULATION CENTER WITH
    A 10 NM EYE. THE INITIAL INTENSITY IS BASED ON PGTW, PHFO, KNES, AND
    ABRF DVORAK INTENSITY ESTIMATES OF 115 KNOTS. UPPER LEVEL ANALYSIS
    INDICATES AN ANTICYCLONE ALOFT IS PROVIDING LOW VERTICAL WIND SHEAR
    (VWS) AND GOOD RADIAL OUTFLOW. TOMAS IS CURRENTLY TRACKING SOUTHWARD
    ALONG THE WESTERN PERIPHERY OF THE SUBTROPICAL RIDE (STR) IN AN AREA
    OF HIGH SEA SURFACE TEMPERATURES (>27 DEGREES CELSIUS). TC 19P IS
    FORECAST TO BEGIN ROUNDING THE STR AXIS AFTER TAU 24 WHEN IT WILL
    BEGIN TO INCREASE IN SPEED AND TURN SOUTHEASTWARD. THE SYSTEM WILL
    BEGIN TO TRANSITION TO AN EXTRATROPICAL SYSTEM BY TAU 48 AND FULLY
    BECOME EXTRATROPICAL BY TAU 72 AS TOMAS INTERACTS WITH THE
    BAROCLINIC ZONE. INTENSITIES WILL WEAKEN AS TC 19P APPROACHES THE
    WESTERLIES WITH INCREASING VWS AND DECREASING OHC. NUMERICAL MODEL
    GUIDANCE IS IN GOOD AGREEMENT WITH THIS FORECAST. MAXIMUM
    SIGNIFICANT WAVE HEIGHT AT 151200Z IS 26 FEET.

    Ciclone Tropicale Ului


    Satellite






    REMARKS:
    151500Z POSITION NEAR 13.1S 158.4E.
    TROPICAL CYCLONE (TC) 20P (ULUI), LOCATED APPROXIMATELY 925 NM NORTH-
    NORTHEAST OF BRISBANE, AUSTRALIA HAS TRACKED WESTWARD AT 04 KTS OVER
    THE PAST SIX HOURS. ANIMATED INFRARED SATELLITE IMAGERY SHOWS DEEP
    CONVECTIVE BANDING WRAPPING INTO A LOW LEVEL CIRCULATION CENTER
    (LLCC) AND A 180820Z SSMIS MICROWAVE IMAGE SHOWS THE MAJORITY OF THE
    DEEP CONVECTION IS LOCATED ON THE WESTERN PERIPHERY. THE INITIAL
    POSITION IS BASED ON TIGHTLY CURVED BANDING AND THE INITIAL
    INTENSITY IS BASED ON PGTW DVORAK INTENSITY ESTIMATES OF 130 KNOTS.
    UPPER LEVEL ANALYSIS INDICATES AN ANTICYCLONE ALOFT IS PROVIDING LOW
    VERTICAL WIND SHEAR (VWS) AND GOOD RADIAL OUTFLOW. ULUI CONTINUES TO
    TRACK ALONG THE NORTHERN PERIPHERY OF THE SUBTROPICAL STEERING RIDGE
    IN AN AREA OF HIGH OCEAN HEAT CONTENT (OHC) AND WARM SEA SURFACE
    TEMPERATURES. TC 20P IS FORECAST TO CONTINUE TO TRACK WESTWARD FOR
    THE NEXT 12 HOURS AND THEN BEGIN TO TURN SOUTHWARD AS THE
    SUBTROPICAL RIDGE (STR) WEAKENS DUE TO AN UPPER LEVEL, MID-LATITUDE
    TROUGH AND A NEAR EQUATORIAL RIDGE (NER) BUILDING IN. BY TAU 72, THE
    STR SHOULD BUILD BACK IN AND BEGIN SPEEDING UP TO THE SOUTHWEST.
    INTENSITIES ARE FORECAST TO STEADILY DECREASE WITH INCREASING VWS
    AND DECREASING OHC. NUMERICAL MODEL GUIDANCE IS DIVIDED IN THE
    TIMING OF THE TURN TO THE SOUTHWEST. THIS FORECAST WAS IN AGREEMENT
    WITH THE MODEL CONSENSUS. MAXIMUM SIGNIFICANT WAVE HEIGHT AT 151200Z
    IS 36 FEET. NEXT WARNINGS AT 160300Z AND 161500Z. REFER TO TROPICAL
    CYCLONE 19P (TOMAS) WARNINGS (WTPS32 PGTW) FOR TWELVE-HOURLY
    UPDATES.

    Ultimo bollettino aggiornato per il ciclone Ului

    REMARKS:
    171500Z POSITION NEAR 14.6S 158.0E.
    TROPICAL CYCLONE (TC) 20P (ULUI), LOCATED APPROXIMATELY 730 NM EAST
    OF CAIRNS, AUSTRALIA, HAS TRACKED SOUTH-SOUTHEASTWARD AT 04 KNOTS
    OVER THE PAST SIX HOURS. AFTER BEING QUASISTATIONARY FOR NEARLY 36
    HOURS ULUI HAS BEGUN TO ACCELERATE WITH THE STRENGTHENING OF THE
    SUBTROPICAL STEERING RIDGE TO THE SOUTH. THE TROUGH THAT HAD BEEN
    RESPONSIBLE FOR THE WEAKENED STATE OF THIS RIDGE IS POSITIONED TO
    MOVE DOWNSTREAM WITHIN THE NEXT 12 TO 24 HOURS. WITH THE TROUGH
    DOWNSTREAM THE RIDGE WILL FURTHER STRENGTHEN AND TRACK THE CYCLONE
    TOWARDS THE EAST COAST OF AUSTRALIA, OF WHICH THE MODEL GUIDANCE IS
    NOW IN EXCELLENT AGREEMENT WITH. THE INITIAL INTENSITY HAS DECREASED
    TO 100 KNOTS IN RESPONSE WEAKENED CENTRAL CONVECTION, WHICH IS MOST
    LIKELY THE CONSEQUENCE OF UPWELLING OF COOLER SUB-SURFACE WATER.
    RECENTLY IMPROVED POLEWARD VENTING SHOULD HELP TO OFFSET SIGNIFICANT
    DECAY OF CENTRAL CONVECTION AND STABILIZE THE INTENSITY NEAR 100
    KNOTS FOR THE NEXT DAY. THE 0600Z DVORAK INTENSITY ESTIMATE FROM
    PGTW INDICATES A 77 TO 102 KNOT SYSTEM. THE SYSTEM WILL COME ASHORE
    SHORTLY AFTER TAU 72 AND WILL DISSIPATE OVER INTERIOR QUEENSLAND
    NEAR TAU 120. THE CYCLONE WILL SLOWLY WEAKEN PRIOR TO LANDFALL DUE
    TO RESTRICTED POLEWARD OUTFLOW AND ELEVATED VERTICAL WIND SHEAR.
    MAXIMUM SIGNIFICANT WAVE HEIGHT AT 171200Z IS 23 FEET. NEXT WARNINGS
    AT 180300Z AND 181500Z. REFER TO TROPICAL CYCLONE 19P (TOMAS)
    WARNINGS (WTPS32 PGTW) FOR TWELVE-HOURLY UPDATES.

    Ciclone tropicale Paul attivo sull'oceano Pacifico Occidentale


    REMARKS:
    282100Z POSITION NEAR 13.3S 136.6E.
    TROPICAL CYCLONE (TC) 22P (PAUL), LOCATED APPROXIMATELY 340 NM EAST
    OF DARWIN, AUSTRALIA, HAS BEEN QUASI-STATIONARY OVER THE PAST SIX
    HOURS. ANIMATED INFRARED IMAGERY AND A RADAR LOOP FROM GOVE,
    AUSTRALIA SHOW DEEPENING CONVECTIVE BANDING WRAPPING TIGHTLY AROUND
    A LOW LEVEL CIRCULATION CENTER (LLCC) WITHIN THE PAST 12 HOURS.
    INITIAL INTENSITY IS BASED ON NORTHEAST ISLAND OBSERVATIONS,
    APPROXIMATELY 30 NM AWAY FROM THE LLCC, OF 38 KNOTS AND 997 MB.
    UPPER LEVEL ANALYSIS INDICATES TC 22P IS LOCATED BENEATH AN AREA OF
    DIVERGENCE AND LOW VERTICAL WIND SHEAR, WITH GOOD RADIAL OUTFLOW.
    PAUL IS CURRENTLY TRACKING IN A WEAK STEERING ENVIRONMENT BETWEEN A
    NEAR EQUATORIAL RIDGE AND A LOW- TO MID-LEVEL SUBTROPICAL RIDGE
    (STR) TO THE SOUTH. AS THE STR BUILDS IN AND TAKES STEERING CONTROL,
    TC 22P IS FORECAST TO TURN SOUTHWESTWARD AND CONTINUE TO INTENSIFY
    AS IT TRACKS OVER THE WARM WATER OF THE GULF OF CARPENTARIA. PAUL IS
    EXPECTED TO REACH LAND BY TAU 32 AND BEGIN DISSIPATING AS A
    SIGNIFICANT TROPICAL CYCLONE BY TAU 48. AVAILABLE NUMERICAL MODEL
    GUIDANCE IS IN POOR AGREEMENT DUE TO DIFFERENCES IN THE STEERING
    ENVIRONMENT DEPICTION. MAXIMUM SIGNIFICANT WAVE HEIGHT AT 281800Z IS
    15 FEET. NEXT WARNINGS AT 290900Z AND 292100Z

    Ciclone tropicale Robyn attivo nell'oceano Indiano meridionale

    REMARKS:
    052100Z POSITION NEAR 16.2S 92.1E.
    TROPICAL CYCLONE (TC) 23S (ROBYN), LOCATED APPROXIMATELY 365 NM
    SOUTHWEST OF THE COCOS ISLANDS, HAS TRACKED EASTWARD AT 01 KNOT OVER
    THE PAST SIX HOURS. ANIMATED INFRARED SATELLITE IMAGERY SHOWS WANING
    DEEP CONVECTION THAT IS BECOMING MORE DISORGANIZED DUE TO 20-30
    KNOTS OF NORTHWESTERLY VERTICAL WIND SHEAR. ACCORDINGLY, DVORAK
    ESTIMATES FROM PGTW, KNES, AND APRF HAVE DROPPED OVER THE LAST 12
    HOURS AND NOW RANGE FROM 30 TO 55 KNOTS. THE CURRENT POSITION IS
    BASED ON A 051854Z AMSU MICROWAVE IMAGE WHICH SUGGESTS THE LOW LEVEL
    CIRCULATION CENTER (LLCC) IS EXPOSED AND LOCATED TO THE NORTHWEST OF
    THE MAIN CONVECTION. AS TC 23S WEAKENS, IT HAS SLOWED IN FORWARD
    TRACK SPEED DUE TO COMPETING STEERING INFLUENCES AT THE LOW TO MID
    LEVELS. OVER THE NEXT 12 HOURS, TC ROBYN IS EXPECTED TO CONTINUE
    WEAKENING AS IT LOSES POLEWARD OUTFLOW (PREVIOUSLY ENHANCED BY A
    PASSING MID-LATITUDE TROUGH) AND START TRACKING WESTWARD UNDER THE
    INFLUENCE OF A LOW- TO MID-LEVEL SUBTROPICAL RIDGE BUILDING IN FROM
    THE WEST. BY TAU 36, THE SYSTEM IS EXPECTED TO DISSIPATE AS A
    SIGNIFICANT TROPICAL CYCLONE AS IT SUCCUMBS TO EXCESSIVE VERTICAL
    WIND SHEAR AND LACK OF A VENTING MECHANISM. THE NUMERICAL MODEL AIDS
    ARE IN GOOD AGREEMENT WITH A WESTWARD TRACK AND THIS FORECAST IS
    SLOWER THAN THE JTWC CONSENSUS IN ORDER TO REFLECT UNCERTAINTY IN
    TRACK SPEED OVER THE NEXT 06 HOURS AS THE SYSTEM MAKES ITS TURN TO
    THE WEST. MAXIMUM SIGNIFICANT WAVE HEIGHT AT 051800Z IS 18 FEET.
    NEXT WARNINGS AT 060900Z AND 062100Z.//

    Nella sua massima potenza ha raggiunto cat 3,adesso con venti superiori ai 63 nodi ( 118 km/h ) è un cat 2, quindi poi dovrebbe procedere e contemporaneamente perdere forza. Per l'estensione non ho trovato nessun dato al riguardo, ma così ad occhio non mi sembra molto esteso.
