Cyclone potential "94B"

Chennai:

Warm at 34 deg and with 60% humidity.

Now(9:13AM) it's warm and with high cloud cover around.

Looking at the latest satellite pic

"94B" has grown in strength during the past 24 hrs.

FNMOC is tracking it from the begining, 2 days ago.

Here's the report & forecast from JTWC...:

AN AREA OF CONVECTION HAS PERSISTED NEAR 11.8N 87.4E,
APPROXIMATELY 425 NM EAST OF CHENNAI, INDIA. MULTISPECTRAL IMAGERY
INDICATES A BROAD LOW LEVEL CIRCULATION CENTER (LLCC) HAS REMAINED
PERSISTENT OVER THE PAST 24 HOURS WITH FLARING CONVECTION OVER THE
LLCC. A 131335Z SSMIS AND A 131526Z AMSU-B PASS INDICATE WEAK
BANDING TOWARD THE LLCC WITH MOST OF THE DEEPEST CONVECTION LOCATED
ON THE SOUTHERN PERIPHERY. THE LLCC IS ELONGATED ALONG A NORTHEAST
TO SOUTHWEST AXIS, BUT CONTINUES TO CONSOLIDATE. UPPER LEVEL
ANALYSIS INDICATES THAT THE LLCC IS LOCATED SOUTH OF AN UPPER LEVEL
RIDGE AXIS PROVIDING GOOD EQUATORWARD AND POLEWARD OUTFLOW AND LOW
VERTICAL WIND SHEAR. SEA SURFACE TEMPERATURES ARE FAVORABLE FOR
DEVELOPMENT THROUGHOUT THE REGION. MAXIMUM SUSTAINED SURFACE WINDS
ARE ESTIMATED AT 15 TO 20 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
POOR.
JTWC doesn't put it as a threat to land as of now.

The latest 48hrs GFS prediction by FNMOC shows

"94B" will head north into Bay and weaken. And some showers forecast for us after 72hrs.

We'll keep monitoring it, thru the day.
