Cyclone threat looms over Tamil Nadu, IMD forecasts heavy rains
What's the story
Tamil Nadu will likely witness a spell of heavy rainfall between Wednesday and Friday as the northeast monsoon's first cyclonic storm over the Bay of Bengal approaches the state. The India Meteorological Department's (IMD) Regional Meteorological Department (RMC), Chennai, issued a red alert in 13 districts for heavy rains and strong winds. The storm's impact would also be felt in Puducherry and Andhra Pradesh.

Why does this story matter?
The red alert means that Tamil Nadu's weather woes are not over just yet. The state is still grappling with the devastating impact of the rainfall witnessed last month. In fact, Tamil Nadu reportedly witnessed 16% excess rainfall compared to the average in the northeast monsoon season so far. Several people died in rain-related incidents while schools/colleges remained shut for several days in November.

What the weather department said
According to RMC, Chennai, a low-pressure area is forming over the southwest Bay of Bengal. This will most certainly strengthen and turn into a depression by Tuesday evening. The RMC also predicted that the weather system will slowly intensify into a cyclonic storm. This will reach the Bay of Bengal along the north Tamil Nadu coast by Thursday morning, resulting in severe rainfall.
