02A - Potential cyclone over E-central Arabian sea


11:30am, Analysis of yesterday's 95A - LOW pressure over E-central Arabian sea shows that it has intensified into a Deep Depression and in verge of becoming a Cyclone.
Position is 15.6N , 68.7E
Wind gusts upto 65 kmph
Pressure is around 996mb


11:30am, visible shot reveals Heavy convective activity over its W,S-W quadrants and less activity over rest of its quadrants.
Heavy rain lashing N-central Kerala coast.

8:30am - JTWC report
~~~~~~~~~~~~~~~~~~~~~~~~~~
TROPICAL CYCLONE (TC) 02A (TWO), LOCATED APPROXIMATELY 325 NM 
SOUTHWEST OF MUMBAI, INDIA, HAS TRACKED NORTH-NORTHWESTWARD AT 08 
KNOTS OVER THE PAST SIX HOURS. ANIMATED INFRARED (IR) SATELLITE 
IMAGERY DEPICTS AN INCREASINGLY DEFINED LOW LEVEL CIRCULATION CENTER 
WITH FLARING CENTRAL CONVECTION AND BROKEN CONVECTIVE BANDING ALONG 
THE WESTERN PERIPHERY. A 092236Z SSMI 85 GHZ MICROWAVE IMAGE 
INDICATES INCREASED CONSOLIDATION IN THE LOW LEVELS AS THE SYSTEM 
HAS BECOME MORE TIGHTLY WRAPPED WHILE THE CONVECTIVE STRUCTURE OF 
SYSTEM HAS REMAINED MARGINAL OVER THE PAST 12 HOURS. THE INITIAL 
POSITION IS BASED UPON THE AFOREMENTIONED SATELLITE IMAGERY WITH 
FAIR CONFIDENCE. THE INITIAL INTENSITY HAS BEEN ASSESSED AT 35 KNOTS 
BASED UPON THE TIGHTLY WRAPPED STRUCTURE SEEN IN THE IMAGERY AS 
DVORAK INTENSITY ESTIMATES FROM PGTW REMAIN AT 30 KNOTS. UPPER LEVEL 
ANALYSIS REVEALS THE SYSTEM IS SOUTH OF THE SUBTROPICAL RIDGE (STR) 
AXIS WITH MODERATE (15 TO 20 KNOTS) LEVELS OF VERTICAL WIND SHEAR 
(VWS) AND GOOD EQUATORWARD OUTFLOW. TC 02A IS CURRENTLY TRACKING 
NORTH TO NORTHWESTWARD ALONG THE MID TO DEEP-LAYER REFLECTION OF A 
NORTH-SOUTH ORIENTED STR STEERING RIDGE LOCATED OVER INDIA. THE 
SYSTEM IS FORECAST TO BEGIN TO TURN WESTWARD IN THE NEXT DAY AS 
ANOTHER STR BUILDS NORTH OF THE SYSTEM AND BECOMES THE DOMINANT 
STEERING INFLUENCE. GRADUAL INTENSIFICATION IS EXPECTED THROUGH TAU 
72, REACHING 70 KNOTS, AS EXTREMELY CONDUCIVE SEA SURFACE 
TEMPERATURES AND GOOD OUTFLOW CONTINUE. INCREASING VWS AFTER TAU 72, 
WILL START A SLOW WEAKENING PROCESS AS THE SYSTEM BEGINS TO APPROACH 
OMAN. LIMITED NUMERIC MODEL GUIDANCE IS IN FAIR AGREEMENT WITH THE 
WESTWARD TRACK WITH SOME SLIGHT DIFFERENCES IN TRANSLATIONAL TRACK 
SPEED. BASED ON THIS, THERE IS LOW CONFIDENCE IN THE FORECAST. 
MAXIMUM SIGNIFICANT WAVE HEIGHT AT 100000Z IS 12 FEET.

Forecast
~~~~~~~~~~~~~~~~~~~~

GFS model suggests that 02A will intensify further and move in N-W direction towards Oman coast during next 48hrs.
The system is expected to become as a named Cyclone in next 36hrs.
02A might fizzle out along Oman coast on 15-Jun.

Posted Monday Night 9th June:

Arabian Sea Low: Well marked, and soon to be a depression, AS-1 has tracked in a hap hazard manner, but overall has moved parallel to the West Coast in the last 48 hrs. 

The red line in the image shows the last 48 hrs track, and stationed almost off the Goa coast now, it has reached vagaries' point of turn now. We had estimated the system to move along the coast till Goa, and turn West thereafter.

My worry is, being situated at 13.6N and 68E, it is within our "de marked" line of 65E, so, now AS-1 at 996 mb, the worry is about the monsoon clouds getting "sucked in" the system. We must hope for and anticipate a quick movement away from the coast, Westwards.
As-1 quick movement Westwards will help in fast organising of the Monsoon favourite off shore coast.
