CHENNAI: Northeast monsoon rain that was first experienced in coastal districts commenced over remaining parts of Tamil Nadu on Friday. Weather models indicate that there is no major rain threat on Deepavali day in Chennai. “Currently, the rainfall activity has shifted to southern districts and delta region, which are getting heavy rain as the trough of low pressure formed over southwest Bay of Bengal has now become less marked and moved from the Comorinarea to Lakshadweep,” meteorological officials said.
