The southern states of Tamil Nadu and Andhra Pradesh, as well as Odisha in the east, experienced heavy downpours yesterday as authorities issued warnings for Tropical Cyclone Michaung, which is likely to hit the southern coast with maximum sustained winds of 90-100 kph (56-62 mph) and gusts up to 110 kph (68 mph), the Indian Meteorological Department said.

Torrential rains and strong winds lashing India's southern and eastern coasts have killed at least six people, officials said, as states there braced for a powerful storm expected to make landfall later Tuesday, reports AP.
