A significant winter storm is forecasted to bring blizzard conditions and high winds to the East Coast, prompting the National Weather Service to issue blizzard warnings for areas including New Jersey, Delaware, Long Island, New York City, and southern Connecticut. The storm, expected from Sunday morning through Monday afternoon, may bring snowfall rates up to 2 inches per hour, potentially accumulating up to 17 inches in New York City, with extreme cases nearing two feet. High winds, gusting between 40 to 70 mph, are anticipated, increasing the risk of power outages and coastal flooding. Residents are urged to prepare for widespread flight cancellations and treacherous travel conditions.
