STORY: Witness video showed the snow-like sea foam at Lawrencetown Beach, churned up after Lee made landfall as a post-tropical cyclone on Saturday. According to the U.S. National Oceanic and Atmospheric Administration, sea foam forms when dissolved organic matter in the ocean is churned up.
The U.S. National Hurricane Center said Lee made landfall on Nova Scotia's Long Island, a small island southwest of Halifax, with estimated maximum sustained winds of 70 mph (110 km/h). Around 120,000 people in Nova Scotia were without power on Saturday as winds knocked down trees and felled power lines. In neighboring New Brunswick, nearly 20,000 people experienced power outages.
