Heavy rain lashed Mumbai again on Thursday leading to waterlogging in some low lying areas, traffic disruptions and significant rises in the catchment areas of the six Thane district lakes that supply water to the city.
Till 8.30am on Thursday, Santacruz recorded 93mm rain while Colaba recorded 57.1mm rain. Data available with the civic body revealed that the Dahisar weather station recorded 241millimetre (mm) of rainfall, highest in the last 24 hours in the city and 48.8mm between 6.30 and 7.30am. The suburbs received 70.6mm rainfall and south Mumbai recorded 44mm rain.
The levels of all six lakes in the neighbouring Thane district rose significantly, with heavy rainfall in their catchment areas. Currently, reservoirs have a total stock of 3.67 lakh million litre. This is nearly 27% of the water the city requires for the year, which needs about 11 to 12 lakh million litres of water from October to July till the next monsoon.
There was waterlogging in areas such as Kalachowkie, Byculla, Worli, Sewree, near Kurla Depot, Kajupada and Sant Dnyaneshwar Marg, Juhu, Goregaon (East) but the water receded quickly. Dahisar subway, Andheri subway and Hindmata were flooded leading to traffic diversions to other roads. BMC’s dewatering pumps were in operation in many areas.
However, the downpour is not likely to continue with weathermen predicting sporadic rain on Friday. “The off-shore trough on the western coast resulted in heavy rain. Monsoon activity decreased towards the evening,” said VK Rajeev, director, western region, IMD.
The rain caused drops in temperatures — while maximum temperature dipped to 26ºC degrees (four below normal) in Colaba, Santacruz recorded a maximum temperature of 27 degrees Celsius. Minimum temperature also fell one degree below normal at 24 degree Celsius at both Colaba and Santacruz. Humidity levels continued to stay high at 93% in Colaba and 95% in Santacruz.
Heavy rainfall in Thane (which recorded 113.6 mm rainfall on Thursday till 4pm) led to waterlogging in areas such as Shivainagar, Udaynagar, Jambli Naka and Vrindavan Society.
