The thunderstorm and rain alerts across 20 states could lead to localised disruptions, including reduced visibility, slippery roads, and potential damage from gusty winds. Residents in affected areas, particularly those in Delhi-NCR, should be cautious of sudden weather changes. The IMD has also highlighted a 15% cumulative rainfall deficit across the country, with several districts in western, southern, and northeastern regions experiencing deficient rainfall. This could have implications for agriculture and water resources in these areas.
