A meeting of the Disaster Management department of Mumbai Municipal Corporation (BMC) for pre monsoon preparations took place recently which was attended by officers’ from Police , Government, army, CRPF, Meteorological department, Central & Western Railway, western railway and other government departments.
Mumbai Municipal Corporation (BMC) published the 19 days of high tide as Red letter days in the rainy season between June 22 and September 21 for this year, which means when the crest of waves at high tide is over four meters and there is heavy rain at same time , the possibility of the city flooding is very high.
The dates of high tides – June -22 to 27, July-21 to 26 , August – 19 to 23 , September – 18 to 21
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 the following days.
24 June 2009 Wednesday 1:41 PM 4.95 m high tide
25 June 2009 Thursday 2:24 PM 4.97m high tide
23 July 2009 Thursday 1:23 PM 5.01m high tide
24 July 2009 Friday 2:03 PM 5.05m high tide
24 July 2009 Friday 2:03 PM 5.05m high tide
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.
Mumbaikars 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.
Request you to advise your friends and relatives outside Mumbai not to plan a trip to Mumbai around these days.
All associates need to avoid low-lying areas that appear to be flooded, “extremely cautious” when driving or walking during periods of flooding. Please exercise caution while moving out and monitor local media reports. Among other sources, weather forecasts are also available at:
