THIRUVANANTHAPURAM: Although the monsoon season has abated, it is anticipated that the Thulavarsham will replenish the dams which initially began with heavy rainfall. In the first three days there has been an excess of 183 percent in rainfall. Thiruvananthapuram received 388% more rainfall than the normal average. Rain is expected to persist for four days in the state due to the influence of a cyclone. The Central Meteorological Department has warned of the possibility of thunderstorms and lightning at isolated locations today.

A low-pressure system prevails over Southwest Jharkhand. The low-pressure system over central Maharashtra has weakened into a cyclonic vortex. Consequently, rainfall continues but there is no state-wide alert.

There is a potential for high waves and sea storms along the Kerala coast until 11:30 tonight. Fishermen and coastal residents are advised to exercise caution, as stated by the National Oceanic and Atmospheric Research Centre. There is a warning against venturing into the sea for fishing due to the possibility of strong winds up to 65 km per hour along the southern Tamil Nadu coast and the Gulf of Mannar.

The rainy season has passed without fully filling the dams. An expected 2018.6 mm of rainfall was projected but only 1326.1 mm was received marking a 34% deficit.

It took a year to reach at least half of the dam's capacity. With the recent rainfall over the last three days, the water level has now reached 51%. However, Idukki's water level remains at only 42%. At the start of October there was a mere 2202 million units of water available for electricity generation. Compared to the previous year, this marks a decrease of 1137 million units in electricity generation. The last significant dry spell in the dams occurred in 2016.
