Now it's "94B"

Take a look at the visible picture from F-15 overpass provided by US Navy

Read the Navy report about the system
AN AREA OF CONVECTION HAS PERSISTED NEAR 7.5N 87.5E,
APPROXIMATELY 450 NM EAST OF COLOMBO, SRI LANKA. ANIMATED
MULTISPECTRAL IMAGERY REVEALS A FULLY EXPOSED LOW LEVEL CIRCULATION
CENTER (LLCC) WITH BANDING CONVECTION ALONG THE NORTHERN AND WESTERN
PERIPHERY. THE CONVECTION IS DISPLACED 60 NM TO THE NORTH AND WEST
DUE TO MODERATE TO STRONG VERTICAL WIND SHEAR. A SYNOPTIC-SCALE
UPPER LEVEL ANTICYCLONE TO THE NORTH AND EAST IS PROVIDING GOOD
POLEWARD OUTFLOW FOR THE DISTURBANCE. MAXIMUM SUSTAINED SURFACE
WINDS ARE ESTIMATED AT 15 TO 20 KNOTS. MINIMUM SEA LEVEL PRESSURE IS
ESTIMATED TO BE NEAR 1005 MB. DUE TO THE MODERATE TO STRONG VERTICAL
WIND SHEAR, THE POTENTIAL FOR THE DEVELOPMENT OF A SIGNIFICANT
TROPICAL CYCLONE WITHIN THE NEXT 24 HOURS IS POOR.

In chennai, we had a mild day with North-North-westerly winds thru the day, and now (11:03PM) it's very calm.
Today's temperature Hi: 29.4°C @ 11:22am and Low: 25.7°C @ 5:06am
Humidity: Hi: 79% @ 1:33am and Low: 60% @ 11:24am, the humidity is on the high side.
Now take a look at the numerical forecast for next 48hrs.

this too suggests a weak "94B". but more to come at the end of this week..!!!
