28 Oct 2012 cloud mass

This is the latest cloud imagery.  Cloud have entered Coramandal coast [i.e between Kodiyakarai and Cuddalore] It will batter the coast.  The other cloud mass is at about 550km east of this coast.  As the 200hPa ridge is just above 13 Deg N latitude it can be presumed that cloud mass will move due WEST only and hit this coast

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

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
