The well-marked low pressure area located about 120 km southeast of Chennai is likely to dissipate on Wednesday, but not before bringing more showers to the city.
On Tuesday, the observatories in Nungambakkam and Meenambakkam recorded a rainfall of 44.5 mm and 40 mm respectively during the 12-hour period ending 8.30 p.m. The rain, which inundated many areas, damaged roads and caused traffic pile-ups, also brought down the day temperature.
According to officials of the Meteorological Department, the temperature was three degree Celsius below the average of 29 degree Celsius for this period of the year.
Automated weather stations commissioned recently in the Ennore port and the Madhavaram campus of Tamil Nadu Veterinary and Animal Sciences University also recorded nearly 40 mm of rainfall each.
Will move closer to coast
The low pressure area would further move closer to the coast and bring showers over north Tamil Nadu and South Andhra Pradesh region on Wednesday.
However, rainfall may not be as heavy as that on Tuesday.
Combined storage level
The city's four reservoirs gained significantly following the showers in their catchment areas since Monday. Their combined storage level stood at 6,400 million cubic feet, against the capacity of 11,057 mcft.
