Yesterday we talked about AS-2 changing stature from today (Friday), and it has.
AS-2 has showed an erratic movement, and has moved due east in the last 6 hrs ! From 10.8N and 60.9E it has shifted to 10.6N and 64.5E (at 10.30 pm IST, Friday). Having deepened to 1004 mb, it has maximum winds at 25 knts in the Northern segment. The clouding around the system is now showing a swirl, and IMD expects the system to deepen more.
Vagaries forecasts a further deepening and a NW movement, initially, and then North.
Coastal Sindh (Pakistan) can get some precipitation in such a scenario (by Tuesday), depending on the movement of the system. The track and strength of AS-2 will be updated on Vagaries regularly.
The other low mentioned in Vagaries ( secondary low) yesterday is now positioned at 12.5N and 68E, just off the Karnataka coast, and also at 1004 mb.This low is embedded in the trough associated with AS-2.
