On March 16 and 20, thunderstorms accompanied by winds of 30–40 kmph are expected at some locations.Impact on wheat CropAgricultural experts say light to moderate rain at this stage could benefit wheat crops by maintaining soil moisture during the final growth phase. However, farmers remain concerned that strong winds, hailstorms or heavy rainfall could damage wheat crops, which are currently in the final stage of ripening before harvest in many parts of Punjab and Haryana.Experts warned that intense storms or gusty winds could cause lodging of wheat plants, affecting grain quality and yields. Farmers have therefore been advised to monitor weather updates closely and take precautionary measures where possible.
