The Monsoon axis is now almost stationary from Sindh(Pakistan) in the west thru Jaisalmer and running thru North MP along the 25N line, into Bangladesh and further Eastwards.
Another trough "aloft" runs along the same lines as the sea level trough.See Thai Chart.
Tuesday would also bring rain showers, a few heavy, to Haryana. Delhi NCR will surely get some regional showers on Tuesday, with weather brightening by Wednesday.
The West Coast off shore trough remains strengthened, but i am searching all charts for the vortex. Its possible the vortex may just re-appear a bit to the North, along the South Gujarat coast by late tonite.
The combined effect of vortex and upper trough is likely to bring rains to Eastern Gujarat region (Ahmadabad) and adjoining regions of Eastern Saurashtra on Tuesday. The Southern Cambay gulf region and Surat will see some precipitations (around 30 mms) on Tuesday.
Wednesday could see the vortex disappearing.
The erstwhile low having merged in the axis, the trough off the East coast has become less marked, or feeble. The line of wind discontinuity along TN has also vanished.
Normal Westerlies will get a bit strong along Chennai region. Shall monitor the formation of the trough again as and when the new low appears in the bay, since a lot depends on its position. Thunder and local activity around Chennai and interior TN may be subdued next few days.
Note on the current El-Nino Situation will be on Vagaries tomorrow..
