As at 3 pm, Tuesday, rains still continue in Mumbai. Heavy showers with regular frequency have been lashing the city and suburbs throughout the day. Rainfall varying at different centres from 50-80 mms have been recorded in Mumbai from 8.30 am till 2.30 pm. Vagaries estimate of 40 mms in the day has been "tossed away" :)
nt, you are partly right i think. Partly because basically the vortex, or UAC was in the upper atmosphere. Winds do affect the ground level, but to a lesser extent. But yes, the winds, which were stormy till morning, have "sobered down" to a greater extent.

But the rain intensity is still heavy. The current pressure position is generally available only after a few hours, but presuming the trend, the vortex is expected to move away or fizzle out within 12 hrs of formation.
Latest position of vortex and 500 hpa chart seen here: http://www.wunderground.com/wundermap/

Rain intensity should decrease from late evening in Mumbai.

Mumbai this year has been battered and pounded by very heavy rains. The total rainfall is racing ahead, and could touch an all time high. Or will it ?
It would be realistic now, to change the poll, and get our reader's view on this.( poll for Mumbai Colaba).
We can conclude the result once the monsoon is over as normally the post monsoon rain in Mumbai is negligible.
Would appreciate your guess/estimate on this.

Some facts:
Rain at Colaba till 31st. Aug: 2896 mms
Normal rain for September: 259 mms
Highest ever annual total: 3482 mms (1954)
Highest ever in September: 1245 mms (1949)
Lowest ever in September: 41 mms (1896)
Shortfall for record as on today:586 mms

Unfortunately, we'll have to cut short the current poll for this. The current poll has 58% showing the possibility of a cyclone from the Bay, and 8% showing it coming from the Arabian Sea.

Meanwhile, all the lakes supplying water to the city have received heavy rain in the last 2 days. The storage of all the lakes combined now stands at 11.59 lmlitres, against a full storage required of 13.0 lmlitres.

As of 31st Aug 2010 all lakes are overflowing just heard on Tv9 mumbai upper Vaitarna & bhatsa overflowing. Howcome storage @ 11.59 lmliters only that means storage capacity only 11.59 & requirement 13 lmlitres?
