The place recorded 820 millimeters of rain over a 24-hour period till Thursday morning. Back in 1943, Cuddalore district had recorded maximum rainfall of 570 millimeters in a single day. Besides surpassing this long held record, Avalanche has received a total of 1,717 millimetres of rains since the downpour began on 4 August. With rain continuing unabated all through Thursday and forecasts predicting more downpour well into the weekend, Avalanche, in all likelihood, may even break its own record in the coming days. The Nilgiris has received 2,304 millimeters of rainfall in the 24-hour period till Thursday morning.

Most of the dams, including the Kundah dam and Avalanche dam in The Nilgiris have reached their capacity thereby facilitating discharge of excess water into the Pilloor dam downstream, which too has come to its brim. The Moyar River in the Mudumalai Tiger Reserve too is in spate following heavy rainfall. However the rain also brought with it a flood of miseries, not only in Avalanche but in the entire district. The district administration has asked people to call its hotline number 1077 to report any emergencies due to flooding.

The Tamil Nadu State Disaster Management Authority (TNSDMA) on Thursday sounded an alert and instructed members of State Disaster Response Force (SDRF) to reach the hilly terrains in The Nilgiris district. A high-level review meeting in this regard is also scheduled in Ooty.

Water level in dams up: Heavy rainfall in Tirunelveli and Kanniyakumari districts, especially in catchment areas, has raised water level of dams in the districts. Rain continued to lash the Western Ghats on Thursday, thus pulling down the mercury levels as well.
