Heavy rains have battered Mumbai last night and continuing in the day on Tuesday. With 113 mms at Colaba, as on Tuesday morning, the 3 day total from Sunday is now 170 mms. And with 98 mms at S'Cruz, the same total, for last 3 days is now at 240 mms.
The rain intensity was over the rate of 80 mms/hour at 3 am on Tuesday morning.
The reason ? The vortex mentioned yesterday has slid downwards off Mumbai. This bubbling of the voretex up and down is causing the very heavy downpours in Mumbai. Initially, if we recall, it was mentioned in the vagaries that the vortex would remain North of Mumbai. But its sliding down is the cause of moisture incursion. Not totally surprising, but un- expected, specially after 2 days of lingering off the coast, when it was time to "move on".
Normally, it would hold this position for a maximum of 12 hrs.
Still i expect the rains to taper off by evening.
Next follow up at 4 pm. Will Mumbai create a new record ? Vagaries Poll change suggested .
