Tropical Cyclone Abele - South Indian Ocean
On November 30, 2010, the 2010 Atlantic hurricane season came to a close, but tropical cyclones are a global phenomenon, and it’s always cyclone season somewhere. On November 29, 2010, Tropical Cyclone Abele formed over the southern Indian Ocean. On December 1, 2010, the U.S. Navy’s Joint Typhoon Warning Center reported that Abele had maximum sustained winds of 40 knots (75 kilometers per hour) with gusts up to 50 knots (95 kilometers per hour). The storm was located some 675 nautical miles (1,250 kilometers) west-southwest of Cocos Island, Australia.
The Moderate Resolution Imaging Spectroradiometer (MODIS) on NASA’s Terra satellite captured this natural-color image of Abele on December 1, 2010. Abele spans hundreds of kilometers over the open ocean. The storm lacks a distinct eye, but sports the apostrophe shape characteristic of tropical cyclones.
Over the past two centuries, tropical cyclones have killed nearly two million people, and forecasters worldwide continually strive to improve storm forecasts. In less developed parts of the globe, a dearth of data has historically hampered predictions. A new tool in forecasters’s arsenal, however, is the Pleiades supercomputer at NASA’s Ames Research Center. Relying on Pleiades’ computing muscle, researchers have been able to model storm formation by feeding the computer data about wind speed, temperature, and mositure. In the case of Cyclone Nargis, which struck in 2008, researchers were able to replicate the tropical cyclone’s formation five days in advance. The project offered hope for improving future predictions worldwide.
"94B" is expected to move in W-N-W direction crossing Srilanka and then into Gulf Mannar on 5/6-Dec.. http://ow.ly/i/62Jv

RT @rameshsethu: Gone in rain: 10 lakh sq m of roads - http://t.co/tvL0J2M via @TOI ~ DMK busy in covering up 2G SCAM and not potholes.
Indian Peninsula with Twin lows on both sides.
In the Arabian Sea, its 93A, with a pressure at 1006 mb and situated at 7N and 62.4E. Winds at 25 knots.
It has shifted slightly east of the previous location,more into warmer waters, and now is elongated and more dis-organised.
Likely track: Initially North.
And in the Bay, 94B, with pressure at 1006 mb, and winds at 15 knots, situated at 5.1N and 89.2 E. Embedded in the monsoon trough, likely to deepen and consolidate, as SST is around 28c in the area.
Likely Track: Will be towards the Sri Lanka and exterme South T.N. coast. And may re-emerge in the Arabian Sea in 2 days.
Both IMD and COLA GFS models agree on Very heavy showers for entire C and N. Tamilnadu coast from 3-Dec till 6-Dec.. http://ow.ly/i/62l1
The present easterlies will peak over Central Tamilnadu coast on 4-Dec and eventually will affect N.TN coast on 5-Dec.. http://ow.ly/i/62jr
This week's 2nd easterlies will start affecting C.coast Tamilnadu from Noon of 3-Dec... http://ow.ly/i/62j9
A new LOW circulation has formed over S-S-E Bay just above 5th parallel .. http://ow.ly/i/62iT ... it'll move in a W-N-W direction.
