JTWC27/1800Z評級Low

(1) AN AREA OF CONVECTION (INVEST 99B) HAS PERSISTED NEAR 6.2N
83.3E, APPROXIMATELY 205 NM EAST OF COLOMBO, SRI LANKA. ANIMATED
ENHANCED INFRARED SATELLITE IMAGERY AND A 271315Z 91GHZ SSMIS
MICROWAVE IMAGE SHOW FLARING CONVECTION WITH SOME MIDLEVEL ROTATION
ABOVE A CONSOLIDATING LLC. A 271533Z ASCAT PASS FURTHER SHOWS THE
ELONGATED NATURE OF THE LLC, WITH 15-20 KT WINDS BELOW THE
CONVECTION AND A WEAK BUT DEFINED RETURN FLOW. THE ENVIRONMENT IS
OVERALL FAVORABLE FOR DEVELOPMENT, WITH LOW-MODERATE (10-20KT) VWS,
STRONG UL DIVERGENCE DUE TO WESTWARD FLOW, AND WARM (29-31C) SSTS.
GLOBAL MODELS ARE SPLIT ON DEVELOPMENT POTENTIAL BUT AGREE ON TRACK,
PREDICTING 99B WILL CONTINUE TRACKING WEST THEN NORTHWEST AFTER
ROUNDING THE INDIAN SUBCONTINENT. ECMWF AND UKMO CALL FOR
DEVELOPMENT INTO A TROPICAL CYCLONE BY TAU 84, WHILE GFS AND NAVGEM
MAINTAIN A WEAK SURFACE CIRCULATION.  MAXIMUM SUSTAINED SURFACE
WINDS ARE ESTIMATED AT 15 TO 20 KNOTS. MINIMUM SEA LEVEL PRESSURE IS
ESTIMATED TO BE NEAR 1007 MB. THE POTENTIAL FOR THE DEVELOPMENT OF A
SIGNIFICANT TROPICAL CYCLONE WITHIN THE NEXT 24 HOURS IS LOW.

(1) THE AREA OF CONVECTION (INVEST 99B) PREVIOUSLY LOCATED
NEAR 6.2N 83.3E, IS NOW LOCATED NEAR 4.8N 77.1E, APPROXIMATELY 310
NM SOUTH OF COCHIN, INDIA. ANIMATED ENHANCED INFRARED SATELLITE
IMAGERY AND A 282352Z 91GHZ SSMIS MICROWAVE IMAGE SHOW FLARING
CONVECTION WITH SOME MID-LEVEL ROTATION ABOVE A CONSOLIDATING LOW-
LEVEL CIRCULATION CENTER (LLCC). THE ENVIRONMENT IS FAVORABLE FOR
DEVELOPMENT WITH LOW (10-15KT) VERTICAL WIND SHEAR (VWS), STRONG UL
DIVERGENCE DUE TO WESTWARD FLOW, AND WARM (29-31C) SSTS. GLOBAL
MODELS ARE SPLIT ON DEVELOPMENT POTENTIAL AND TRACK. ECMWF SHOWS THE
SYSTEM TRACKING NORTH AND TURNING WESTWARD TOWARD THE ARABIAN
PENINSULA WHILE NAVGEM SHOWS INVEST 99B TRACKING MORE NORTHWARD
ALONG THE WEST COAST OF THE INDIAN SUBCONTINENT. NAVGEM CALLS FOR
DEVELOPMENT INTO A SIGNIFICANT TROPICAL CYCLONE BY TAU 72, WHILE GSM
AND GFS MAINTAIN A WEAK SURFACE CIRCULATION. MAXIMUM SUSTAINED
SURFACE WINDS ARE ESTIMATED AT 20 TO 25 KNOTS. MINIMUM SEA LEVEL
PRESSURE IS ESTIMATED TO BE NEAR 1007 MB. THE POTENTIAL FOR THE
DEVELOPMENT OF A SIGNIFICANT TROPICAL CYCLONE WITHIN THE NEXT 24
HOURS IS UPGRADED TO MEDIUM.

REMARKS:
300900Z POSITION NEAR 9.3N 74.5E.
30OCT19. TROPICAL CYCLONE 05A (FIVE), LOCATED APPROXIMATELY 620 NM
SOUTH OF MUMBAI, INDIA, HAS TRACKED NORTHWESTWARD AT 14 KNOTS OVER
THE PAST SIX HOURS. THE CURRENT POSITION IS SITUATED WITHIN A
LOW-LEVEL CIRCULATION CENTER EVIDENT IN 300507Z METOP-B ASCAT PASS
AND ON A 300600Z PGTW SATELLITE FIX. THE INTENSITY OF 35 KNOTS IS
SUPPORTED BY 35 KNOT WINDS EVIDENT IN THE ASCAT DATA. TC 05A HAS
CONSOLIDATED TO THE SOUTH OF AN UPPER-LEVEL RIDGE AXIS, IN AN AREA OF
MODERATE EASTERLY VERTICAL WIND SHEAR (15 TO 20 KNOTS), FAVORABLE
WESTWARD DIFFLUENCE ALOFT AND WARM SEA SURFACE TEMPERATURES (29-30C).
THE SYSTEM IS TRACKING NORTHWESTWARD ALONG THE PERIPHERY OF A
SUBTROPICAL STEERING RIDGE SITUATED OVER CENTRAL INDIA. THE CYCLONE
IS EXPECTED TO CONTINUE TRACKING ALONG THE PERIPHERY OF THE CURRENT
STEERING RIDGE THROUGH TAU 72, BEFORE TURNING WESTWARD IN THE
EXTENDED RANGE AS ADDITIONAL RIDGING BUILDS TO THE NORTH. THE
MAJORITY OF THE AVAILABLE DETERMINISTIC AND ENSEMBLE MODEL FORECAST
GUIDANCE SUPPORTS THIS SCENARIO. HOWEVER, THE MOST RECENT RUN OF THE
UKMET, GALWEM AND NAVGEM MODELS INDICATE THAT THE SYSTEM MAY MOVE
THROUGH A WEAKNESS DEVELOPING IN THE STEERING RIDGE AND TURN
NORTHEASTWARD TOWARD NORTHWESTERN INDIA DURING THE EXTENDED PERIOD.
THIS ALTERNATE SCENARIO IS NOTEWORTHY, BUT HAS A LOWER PROBABILITY OF
OCCURRING. STEADY INTENSIFICATION IS ANTICIPATED THROUGHOUT THE
FORECAST PERIOD AS TC 05A MOVES CLOSER TO THE UPPER-LEVEL RIDGE AXIS
AND VERTICAL WIND SHEAR DECREASES. BASED ON NOTED DISCREPANCIES IN
NUMERICAL MODEL SOLUTIONS, CONFIDENCE IN THE JTWC TRACK FORECAST IS
LOW. MAXIMUM SIGNIFICANT WAVE HEIGHT AT 300600Z IS 12 FEET. NEXT
WARNINGS AT 301500Z, 302100Z, 310300Z AND 310900Z. REFER TO TROPICAL
CYCLONE 04A (KYARR) WARNINGS (WTIO31 PGTW) FOR SIX-HOURLY UPDATES.//

REMARKS:
031500Z POSITION NEAR 17.8N 65.4E.
03NOV19. TROPICAL CYCLONE (TC) 05A (MAHA), LOCATED APPROXIMATELY 432
NM SOUTH OF KARACHI, PAKISTAN, HAS TRACKED WEST-NORTHWESTWARD AT
04 KNOTS OVER THE PAST SIX HOURS. ANIMATED ENHANCED INFRARED
SATELLITE IMAGERY DEPICTS A RAPIDLY CONSOLIDATING SYSTEM WITH A 7NM
EYE, WHICH SUPPORTS THE CURRENT POSITION WITH GOOD CONFIDENCE. A
031053Z SSMIS 91GHZ IMAGE SHOWS AN ASYMMETRIC CONVECTIVE CORE WITH A
SMALL MICROWAVE EYE FEATURE. THE CURRENT INTENSITY IS ASSESSED
AT 80 KNOTS BASED ON A PGTW DVORAK INTENSITY ESTIMATE OF T4.5 (77
KNOTS). UPPER-LEVEL ANALYSIS REVEALS A FAVORABLE ENVIRONMENT WITH
NEAR-RADIAL OUTFLOW AND LOW VERTICAL WIND SHEAR (VWS). TC 05A IS
TRACKING WEST-NORTHWESTWARD ALONG THE SOUTHERN PERIPHERY OF A
SUBTROPICAL RIDGE (STR) POSITIONED TO THE NORTH AND IS FORECAST TO
TRACK WEST-NORTHWESTWARD TO NORTHWESTWARD THROUGH TAU 36. AFTER TAU
36, THE SYNOPTIC STEERING ENVIRONMENT BECOMES MORE COMPLEX AS STRONG
WESTERLY FLOW DIGS OVER THE NORTHERN ARABIAN SEA ERODING THE STR,
WHICH REGRESSES WESTWARD. THIS WESTERLY FLOW WILL GRADUALLY DIG
SOUTHWARD OVER THE CENTRAL ARABIAN SEA AND WILL PRODUCE AN ABRUPT
EASTWARD TRACK CHANGE. THE BULK OF THE NUMERICAL MODEL VORTEX
TRACKERS SUPPORT THIS SCENARIO, HOWEVER, THERE IS HIGH UNCERTAINTY
IN THE JTWC TRACK FORECAST DUE TO THE COMPLEX, EVOLVING STEERING
ENVIRONMENT. TC 05A SHOULD PEAK WITHIN THE NEXT 24 HOURS TO A PEAK
INTENSITY OF 100 KNOTS. AFTER TAU 24, THE SYSTEM WILL GRADUALLY
WEAKEN AS IT INTERACTS WITH THE CONVERGENT WESTERLIES AND
INCREASINGLY HIGHER VWS. MAXIMUM SIGNIFICANT WAVE HEIGHT AT 031200Z
IS 26 FEET. NEXT WARNINGS AT 032100Z, 040300Z, 040900Z AND 041500Z.//
