What is the actual "designation" of AS 1 ??
Here the IMD map shows a trough along the west coast, without a low. But, they have an announcement of a UAC embedded in the trough, off the Mah. coast.
A Thai map on Sunday shows a low of 1000 mb , off Mumbai, but clearly descended to lower levels.
The NPMOC/JTWC tropical note mentions it as a "low level circulation" at 1003 mb.
In any case, its a system. This system, now at 17.5N and 72E, off Mumbai, creating huge cloud masses off Mumbai.See wundermap @ 11.30 am IST.
It is pulling up the SWM at a faster than normal speed along the coast. The trough, getting stremgthened with embedded system, pulls the SW winds and moisture into the coast. This happens during the on-going monsoon period also.
Whether the As-1 moves N or NW is to be seen.Could still move NW as the jet streams show.
Mumbai will get thundershowers by evening with gusty winds. Thundercells are developing in the north-east as of now (1.30 pm). Showers frequency more in evening.
