(1) THE AREA OF CONVECTION (INVEST 91B) PREVIOUSLY LOCATED
NEAR 5.1N 89.7E, IS NOW LOCATED NEAR 6.1N 88.1E, APPROXIMATELY 620
NM SOUTHEAST OF CHENNAI, INDIA. ANIMATED MULTISPECTRAL SATELLITE
IMAGERY DEPICTS A CONSOLIDATING LOW LEVEL CIRCULATION CENTER (LLCC)
WITH DEEP CONVECTIVE BANDING WRAPPING TIGHTLY INTO THE CENTER. A
290632Z AMSR-2 91GHZ MICROWAVE IMAGE SHOWS A SIGNIFICANTLY IMPROVED
SYSTEM WITH DEEP FRAGMENTED BANDING WRAPPING INTO THE CENTER FROM
THE NORTHERN AND WESTERN QUADRANTS. A 290404Z ASCAT PASS SHOWED A
SLIGHTLY ELONGATED LLCC WITH 25-30 KNOT WINDS PRESENT ALONG THE
SOUTHERN SEMI-CIRCLE. THE DISTURBANCE IS TRACKING NORTHWESTWARD IN A
MARGINALLY FAVORABLE ENVIRONMENT WITH STRONG DIVERGENCE AND WARM SEA
SURFACE TEMPERATURES OFFSETTING MODERATE (15-20 KNOT) VERTICAL WIND
SHEAR. GLOBAL MODELS ARE IN AGREEMENT ON FURTHER INTENSIFICATION
OVER THE NEXT 1-2 DAYS AS THE DISTURBANCE TRACKS TOWARDS INDIA.
MAXIMUM SUSTAINED SURFACE WINDS ARE ESTIMATED AT 25 TO 30 KNOTS.
MINIMUM SEA LEVEL PRESSURE IS ESTIMATED TO BE NEAR 1003 MB. THE
POTENTIAL FOR THE DEVELOPMENT OF A SIGNIFICANT TROPICAL CYCLONE
WITHIN THE NEXT 24 HOURS IS UPGRADED TO HIGH. SEE REF A (WTIO21 PGTW

Pre-Cyclone Watch for north Tamil Nadu and Puducherry coasts : Yellow Message
Latest observations & satellite imagery indicate that a depression has formed over southeast
Bay of Bengal and lay centred at 1730 hrs IST of today, the 29th November, 2016 near Latitude 6.5ºN
and Longitude 87.5ºE, about 1070 km east-southeast of Chennai, 1030 km east-southeast of
Puducherry and 720 km east-southeast of Trincomalee (Srilanka). The system is very likely to move
west-northwestwards, intensify into a deep depression during next 24 hrs and into a cyclonic storm in
subsequent 24 hrs. It is very likely to cross north Tamil Nadu coast between Vedaranniyam and
Chennai by 2nd December morning
