2009 Flood Warnings for Mumbai

A communique from BMC is being circulated for information.

Floods – 2009 : Mumbai

Floods in Mumbai are attributable to simultaneous occurrence of rainfall and high tides. If, the rainfall is in excess of 200 mm in a day (24 hrs), floods can occur anytime irrespective of tides. However, if there is moderate rainfall but the tide is in excess of 4.50 meters at the same time, the city of Mumbai is sure to get flooded.

Accordingly, heavy floods are anticipated on the following days in Mumbai, if there is excessive rainfall at the time of high tides, since the tides are extremely high on these days: –

      Date   Day   Time Ht. of Tide ( m ) 
24 June 2009 Wednesday 1:41 PM 4.95
25 June 2009 Thursday 2:24 PM 4.97
23 July 2009      Thursday 1:23 PM     5.01   
24 July 2009      Friday 2:03 PM 5.05
25 July 2009 Saturday 2:43 PM 4.94

BMC has already planned to keep the schools closed on 24 July 2009 since the tide level is record high of last 100 years on this day.

Mumbaites are, therefore, requested to cooperate with the administration by restricting their movements and certainly not to take their vehicles out on the roads these days.

There are speculations about very high waves on 22 July 2009 due to solar eclipse. 

Public should, therefore, keep away from the beaches that day.
