Steady light/medium rain throughout the pre dawn hours, indicated a "wettish" night for Mumbai.
Now, the system from the bay is almost broken, and seems to be moving west, and weakening along its path.
So, for Mumbai, it should be a typical July day initially. A few heavy downpours, but I think the rains can reduce a bit by forenoon. A little "brightening up" possible around mid-day, but again, some showers could be expected by evening, more in suburbs.
Can expect around 30 mms of rain today.
