The flash flood comes amid the India Meteorological Department's forecast, which said that heavy to very heavy rainfall is likely in parts of southern and western Tamil Nadu till May 20.

The weather department said that cyclonic circulation over Southwest Bay of Bengal and adjoining South Sri Lanka now lay over Comorin area and adjoining South Tamil Nadu coast.

"Fairly widespread to widespread light to moderate rainfall accompanied with thunderstorm, lightning and gusty winds (40-50 Kmph) likely over Tamil Nadu, Puducherry and Karaikal during the week," IMD said in its bulletin.

Meanwhile, the Nilgiris district administration said that very heavy rains have been predicted from May 18-20 in Ooty, asking people to "avoid" visiting the hilly tourism attraction during this time.

District Collector M Aruna said the India Meteorological Department has issued an "orange alert" forecast, which means heavy rainfall of 6 cm-20 cm on May 18, 19 and 20.

"Those coming here should have all the required protection. If possible you can avoid travelling here during this period," she told reporters after chairing a meeting with officials of the Revenue, Police and Fire and Rescue Services department on rain preparedness.
