NEW DELHI: Days after thunderstorms wreaked havoc across the country, claiming at least 129 lives, the Met department has issued another storm warning for north India for the next two days. Reacting to the alert, Haryana education minister Ram Bilas Sharma announced that all schools in the state will remain closed on Monday and Tuesday.

Thunderstorm activity with similar wind speeds is also "very likely" over Punjab and Haryana on Monday, while squalls and hailstorms could occur in the two states on Tuesday. For Delhi-NCR, the department said very light rain accompanied with strong gusty winds is likely (26-50% probability) on Monday morning.
