THIRUVANANTHAPURAM: The state is yet to receive significant rain even as the first month of monsoon is about to end. Till yesterday, the state experienced 65 percent less rain. The Monsoon winds, which had lost strength under the influence of Cyclone Biparjoy, are yet to regain strength. The rains will intensify only when the monsoon winds get stronger and reach the Kerala coast. The Meteorological Department stated that it has observed some favourable factors for the strengthening of the wind. Favourable factors are the activation of low-pressure areas along the Kerala coast and the possible formation of low pressure over the Bay of Bengal on Sunday.

According to researchers, the climate has changed significantly since the 2018 flood. While Kerala used to receive above-average rainfall in the first half of the monsoon until 2018, June, the rainfall declined considerably in subsequent years. Since then, Kerala has been receiving less than half of the expected rainfall in the month of June. The situation is a little worse this time. Instead of getting 511.1 mm of rain, the state received only 180.4 mm of rain so far. Wayanad and Idukki regions, which used to receive more rain, have received less rain this year. This deficiency can be resolved only if the state receives heavy rains in the coming days.
