Chennai, Oct 31: The city is bracing for Cyclone Nilam, which is likely to bring heavy rain and gusty winds that could reach speeds up to 65kmph.
By 5pm on Tuesday, the cyclone was 500km southeast of Chennai. It was stationary for more than 12 hours but started moving in a north-northwesterly direction, and is likely to cross the shore between Nellore in AP and Cuddalore in TN.
"Chennai will have a bit of rough weather on Wednesday evening as the cyclone moves closer," said IMD deputy director general Y E A Raj.
The system started as a trough of low pressure over the Andaman and Nicobar Islands on Friday.
