SOUTHWEST OF KOLKATA, INDIA, HAS TRACKED WESTWARD AT 08 KNOTS
OVER THE PAST SIX HOURS. THE ENERGY ASSOCIATED WITH THE SYSTEM
MAY CARRY OVER THE INDIAN SUBCONTINENT AND INTO THE NORTH
ARABIAN SEA AT SOME POINT. THERE IS GREAT UNCERTAINTY WHERE
PRECISELY THE VORTEX MIGHT RE-EMERGE INTO OPEN WATERS AND THE
INTENSITY AT WHICH IT MIGHT DO SO, SO JTWC WILL CONTINUE TRACKING
THE SYSTEM BUT FOREGO WARNINGS UNTIL SUCH TIME AS CONDITIONS
WARRANT. THIS IS THE FINAL WARNING ON THIS SYSTEM BY THE JOINT
TYPHOON WRNCEN PEARL HARBOR HI. THE SYSTEM WILL BE CLOSELY MONITORED
FOR SIGNS OF REGENERATION.//

JTWC重新評級LOW
(2) AN AREA OF CONVECTION (RMNTS 03B) HAS PERSISTED NEAR 20.3N
76.7E, APPROXIMATELY 70 NM EAST-NORTHEAST OF MUMBAI. THE REMNANTS OF
03B CONTINUE TO TRAVEL WEST ACROSS THE INDIAN SUBCONTINENT THROUGH
AN AREA OF LOW (10-15 KTS) VERTICAL WIND SHEAR (VWS) AND ROBUST
EQUATORWARD OUTFLOW. SURFACE OBSERVATIONS INDICATE WEAK LOW LEVEL
TURNING ON THE NORTHEAST SIDE OF AN AREA DEEP CONVECTION. NUMERICAL
MODELS ARE IN GOOD AGREEMENT THAT THE REMNANTS OF 03B WILL
CONSOLIDATE AND INTENSIFY AS IT MOVES INTO THE NORTH ARABIAN SEA IN
THE NEXT FEW DAYS. MAXIMUM SUSTAINED SURFACE WINDS ARE ESTIMATED AT
15 TO 20 KNOTS. MINIMUM SEA LEVEL PRESSURE IS ESTIMATED TO BE NEAR
1002 MB. THE POTENTIAL FOR THE DEVELOPMENT OF A SIGNIFICANT TROPICAL
CYCLONE WITHIN THE NEXT 24 HOURS IS LOW.

IMD 00Z再度升格CS, 命名Shaheen
The Deep Depression over northeast Arabian Sea off Gujarat coast moved
west-northwestwards with a speed of about 25 kmph, during past 6 hours, intensified
into a Cyclonic Storm ‘Shaheen’ and lay centred at 0530 hrs IST of today, the 01st
October, 2021, near latitude 23.2°N and longitude 65.3°E, about 400 km westnorthwest of Devbhoomi Dwarka (Gujarat), 260 km south-southwest of Karachi
(Pakistan) and 530 km east-southeast of Chabahar Port (Iran).
It is very likely to further intensify into a Severe Cyclonic Storm during the next
24 hours and move west-northwestwards during next 36 hours. Thereafter it is likely to
re-curve west-southwestwards skirting Makran coast, move towards Oman coast
across Gulf of Oman and weaken gradually.
