There is good news for people who are battling the after-effects of rains in the city.
The rains are expected to reduce from Thursday, according to Meteorological Department.
The historic rain of the century, in a single day in December, had left the city devastated on Tuesday.
The rainfall of 29.4 cm had beaten the earlier record of 26 cm for December in 1901.
The trough of low pressure has become a low-pressure area over southwest Bay of Bengal off Sri Lanka and North Tamil Nadu coast. This is expected to bring widespread rains over coastal districts.
Officials of the Meteorological Department said while rains might be moderate over Chennai and neighbouring areas, north coastal districts such as Cuddalore and Karaikal might witness heavy to very heavy rains on Friday.
Rainfall in TamilNadu during the last 6 days:
Actual Rainfall : 86.5 mm
