Wider weather episode

Strong low pressure shifted northeast through the eastern Great Lakes on January 13, 2024, sending a warm front through during the morning hours, followed quickly by a cold front. Strong winds produced by this system, combined with peaking high astronomical tides associated with a recent new moon, produced widespread moderate to major coastal flooding along the entire southeast New York coastline and along the Lower Hudson River.
