SWM remains weak in
SWM entered Southern Sri Lanka as a weak current (Vagaries' report) on the 26th, and still remains weak. There was little rainfall in the Southern regions today (Sunday), with Kurunegala measuring 14 mms and Ratnapura getting 11 mms.
The attached sat. image from wundermap (Sunday evening 6.30 pm) shows the SWM still restricted to the Southern half. Anticipitated by Vagaries to cover the Island by the 29th, but seeing the conditions, the advance is not possible today.
Another sat image shows the Kerala region as on Sunday evening, 6.30 pm IST. I feel, (with ref. to IMD statement), the SWM is still 24/36 hrs away. The region
had 2 days of pre-monsoon rain, as mentioned in our blog.
With regards to the Bay sector, the trough off the eastern coast is also weakening, and stationary, again, not allowing the SWM to advance further to cover the Bay Islands.
Vagaries' northern limit map of SWM remains unchanged.
