The Arabian Sea branch of SWM strength fizzled away as of now and confined to Omen, Yemen, and Somalia and adjoining Arabian Sea. However the Bay branch is relatively better because of the strength of HIGH in south Indian Ocean at 95 Deg East. The clouding in the Bay near Malacca straight fed by weak SWly winds may lead to formation of low pressure area.
The Gradient Level Wind Analysis is a snapshot of the airflow near the surface of the earth. The arrowed lines are called streamlines and represent the direction of the wind. The dashed lines are called isotachs, and connect points of equal wind speed. Geostropic winds exist in locations where there are no frictional forces and the isobars are straight. However, such locations are quite rare. Isobars are almost always curved and are very rarely evenly spaced. This changes the geostrophic winds so that they are no longer geostropic but are instead in gradient wind balance. They still blow parallel to the isobars, but are no longer balanced by only the pressure gradient and Coriolis forces, and do not have the same velocity as geostrophic winds.

Usually during SWM withdrawal TS activity will be more over EAST coast . This time it is pronounced over west.

Analysis show a low,mid-level circulation over S Thailand, S Myanmar and popping into Andaman sea ... http://ow.ly/i/77bbf
In next 2 days, this circulation is expected to drift W-N-W, N-W , intensify to marked LOW or even a depression and come near to Andamans !
The upcoming E Bay system is expected to become as a Cyclone or even a S.Cyclone and cross Odisha coast on 12/13-Oct http://ow.ly/i/77bgd
The upcoming Bay system can be a repeat of 2013's Cyclone Phailin ... for more check this out ... http://ow.ly/Ciizt
