For two more days, city residents may have to plan their evenings to avoid getting drenched in heavy showers.

On Wednesday, pleasant weather prevailed, as it has over the last week or so, with Nungambakkam and Meenambakkam recording maximum temperatures of 31.4 degree Celsius and 31.3 degree Celsius, nearly three degrees lower than the average.

Nungambakkam and Chembarambakkam received 14.1 mm of rainfall and Meenambakkam 2.8 mm of rainfall over the past 24 hours until 8.30 a.m. on Wednesday.

The continual formation of a weak, low pressure area over the head of the Bay of Bengal this month is bringing regular showers to the State’s northern districts, particularly to Chennai and its neighbourhood, officials of the meteorological department said.

On Wednesday evening, Doppler radar images indicated rains in Ponneri and Tiruvallur and other localities 40 km north of city. There was also extensive clouding, and this kept the city cool.

Nungambakkam and Meenambakkam have so far registered 137 mm and 146 mm of rainfall this month against the normal rainfall of 100 mm. This is much more than the amount of rainfall recorded last July, Mr. Raj said.
