Havana — Hurricane Oscar made landfall on Sunday evening in Cuba, where residents were preparing for more chaos and misery as the country grapples with a nearly nationwide power outage in its third day. The arrival of Oscar, after the Friday collapse of Cuba's largest power plant crippled the whole national grid, piles pressure on a country already battling sky-high inflation and shortages of food, medicine, fuel and water. Cuba's government said power would be reinstated for the majority of the country by Monday evening, with President Miguel Diaz-Canel warning his government would not tolerate public disturbances during the outage. Oscar, a Category 1 storm, made landfall in eastern Cuba at 5:50 pm local time (2150 GMT) on Sunday, the US National Hurricane Center said.
