SWM should have no problem scaling up to 20N. After this point, in view of the impending "threat" from M4, I would review the further advance of the SWM.
Update on AS-1. At 15.8N and 68.7 E, its a low off the Goa coast, a little more to the west than the previous location. Concentrated clouding is seen in the western/South-western quadrant. At 1002 mb, and embedded in the off shore trough now, AS-1 will deepen slowly, and track NW.
The off shore trough should remain intact, and gear up the SWM to move into Goa.Likely by Sunday.
