WRAPPING AROUND A CONSOLIDATING LOW LEVEL CIRCULATION CENTER. UPPER
LEVEL ANALYSIS SHOWS FAVORABLE CONDITIONS FOR DEVELOPMENT WITH
DIFFLUENCE ALOFT AND LOW (<15 KTS) VERTICAL WIND SHEAR. SEA SURFACE
TEMPERATURES ARE FAVORABLE AT 29-30 DEGREES CELSIUS. GLOBAL MODELS
ARE IN FAIR AGREEMENT SHOWING MINIMAL INTENSIFICATION OF 92B AS IT
TRACKS TO THE NORTHWEST. MAXIMUM SUSTAINED SURFACE WINDS ARE
ESTIMATED AT 20 TO 25 KNOTS. MINIMUM SEA LEVEL PRESSURE IS ESTIMATED
TO BE NEAR 1004 MB. THE POTENTIAL FOR THE DEVELOPMENT OF A
SIGNIFICANT TROPICAL CYCLONE WITHIN THE NEXT 24 HOURS IS UPGRADED TO
MEDIUM.

Sub: Depression over southwest Arabian Sea
Latest observations indicate that a depression has formed over southwest Arabian Sea and lay
centred at 1430 hrs IST of today, the 08
th December, 2019 near latitude 9.4°N and longitude 62.2°E, about 970
km east-southeast of Socotra Island (Yemen) and 1540 km west-southwest of Cochin. It is very likely to
intensify into a deep depression during next 24 hours. It is very likely to move west-northwestwards till 9th

MARGINAL EQUATORWARD OUTFLOW. SEA SURFACE TEMPERATURES ARE FAVORABLE
