Light to moderate rain showers brought much-needed relief to residents of idukki and Ernakulam on Sunday evening, easing the intense summer heat. The rainfall, accompanied by cool and windy conditions, provided a temporary break from rising temperatures across the state.

However, the India Meteorological Department (IMD) has cautioned that this relief may be short-lived, as both rain and heat alerts remain in place for multiple districts in Kerala.

According to IMD, thunderstorms with light to moderate rainfall and gusty winds reaching up to 40 kmph are likely over isolated areas in: Idukki, Ernakulam and Wayanad.

This alert is valid for the next few hours, with residents advised to stay cautious of sudden weather changes.
