"93W" is now having "Almost a core"

10:30pm, "93W" over S-central Bay now have "Almost a core" ... still pressure is near 1006mb and tracking West.
Showers seen very near to Central Tamilnadu coast.
If the track continues to be West, then showers may break over central Tamilnadu coast during early hours of Sunday.

7:30pm, Latest on "93B" .. now its over S-central Bay and lots of convective activity seen.. Still a low pressure.. http://ow.ly/i/1485h 

Tropical Cyclone Murjan



Tropical Cyclone Murjan made landfall on the Horn of Africa on October 25, 2012, as the Moderate Resolution Imaging Spectroradiometer (MODIS) on NASA’s Terra satellite captured this natural-color image. The storm lacked the distinct eye and spiral shape characteristic of strong storms, but its clouds still spanned hundreds of kilometers.
Murjan was not a powerful storm. The U.S. Navy’s Joint Typhoon Warning Center reported wind speeds of just 35 knots (65 kilometers per hour), but although the storm did not bring high winds, it did bring heavy rains. AccuWeather reported that severe thunderstorms soaked Somalia ahead of the cyclone, and continued rain was expected for northern Somalia. Heavy rains and potential flash floods were also expected for Djibouti and eastern Ethiopia.
Showers expected to start ALL along Tamilnadu coast & #Chennai from Sunday !

S.Tamilnadu coast to get more rain till morning of 29-Oct.. and more widespread and HEAVY after that !

Next W.D is expected to reach W.Kashmir on 31-Oct..!

From early hrs of 29-Oct till 31-Oct.. HEAVY rain forecast ALL along Tamilnadu coast... http://ow.ly/i/146zN 
IMD-GFS expects the Bay circulation to be a LOW system while the Arabian sea system to become as a strong Cyclone.. http://ow.ly/i/146tY

Now almost ALL models suggest a N,N-E.Srilanka landfall for Bay LOW on 29-Oct ... http://ow.ly/i/146uM 

S-S-E Arabian sea circulation persists and expected to intensify and move W-N-W .. http://ow.ly/i/146sL

The presence & intensification of S-S-E Arabian sea circulation may drag the Bay circulation to drift W-S-W .. http://ow.ly/i/146t7 
2:30pm, Latest location of S-central Bay low "93W" is 11.7N , 88.7E .. Pressure at 1007mb .. http://ow.ly/i/146rt

By 29-Oct.. the circulation over Bay is expected to become strong and hit N,N-E.Srilanka ... http://ow.ly/i/146rV

NOGAPS suggests that the circulation in Bay, from its present location is expected to drift W-S-W towards N.Srilanka in next 24hrs.
If the Bay circulation strengthens further.. then DRY conditions will prevail along N,central Tamilnadu coast, #chennai till midnight 28-Oct
6am, Showers seen over S,S-E Tamilnadu coast ... http://ow.ly/i/144AE 

Latest on "93W" over Bay

6:30am IST Satellite pic shows.. heavy convective activity seen in and around the system. Expected to become a LOW pressure system in next 24hrs. Now the pressure is around 1007mb.

THE AREA OF CONVECTION PREVIOUSLY LOCATED NEAR 11.7N 
94.0E, IS NOW LOCATED NEAR 10.9N 92.5E, APPROXIMATELY 580 NM WEST-
SOUTHWEST OF BANGKOK, THAILAND. ANIMATED ENHANCED INFRARED 
SATELLITE IMAGERY REVEALS PERSISTENT CONVECTION WRAPPING AROUND AN 
IMPROVING LOW LEVEL CIRCULATION CENTER (LLCC). A 0544Z OSCAT PASS 
REVEALS A WELL DEFINED BUT WEAK (10-15 KT) LLCC. UPPER LEVEL 
ANALYSIS AND ANIMATED WATER VAPOR IMAGERY REVEALS THE AREA IS JUST 
SOUTH OF THE SUBTROPICAL RIDGE AXIS WITH DIVERGENCE ALOFT GIVING 
SOME SLIGHT POLEWARD OUTFLOW. VERTICAL WIND SHEAR IN THE AREA 
REMAINS LOW (05-10 KNOTS). SEA SURFACE TEMPERATURES IN THE AREA ARE 
FAVORABLE (28-30 DEGREES CELSIUS) FOR DEVELOPMENT. MODEL GUIDANCE 
DEPICTS CONTINUED ORGANIZATION OVER THE NEXT 24-48 HOURS. MAXIMUM 
SUSTAINED SURFACE WINDS ARE ESTIMATED AT 10 TO 15 KNOTS. MINIMUM 
SEA LEVEL PRESSURE IS ESTIMATED TO BE NEAR 1007 MB. DUE TO 
IMPROVING CONVECTIVE ORGANIZATION AND NUMERICAL GUIDANCE, THE 
POTENTIAL FOR THE DEVELOPMENT OF A SIGNIFICANT TROPICAL CYCLONE 
WITHIN THE NEXT 24 HOURS IS UPGRADED TO MEDIUM
2 circulations.. 1 over S-E Arabian sea and another E-central Bay ... http://ow.ly/i/144vc

S-E Arabian sea circulation is expected to become a cyclone and track N-W in next 3 days .. http://ow.ly/i/144w0 
#chennai - a dry morning with almost NO cloud formations!.. meaning the moisture is being sucked in by 2 systems.. S-E arabian sea + Bay.
