Hurricane Erin strengthened into a powerful Category 4 storm Saturday in the Caribbean, where it threatened to dump flooding

U.S. shores are unlikely to see a direct hit, but a strong offshore hurricane can produce massive and dangerous waves well away from its center.

A video shared from San Juan, Puerto Rico, shows the city starting to feel the effects of Hurricane Erin on Saturday, Aug. 16.

Hurricane Erin has strengthened into a Category 2 storm as it approaches Puerto Rico and the Virgin Islands, bringing heavy rains that could cause flooding and landslides.

Hurricane Erin has exploded into a Category 5 hurricane in the Caribbean, according to the National Hurricane Center. The storm is currently north of Anguilla, with winds of 160 mph.

As of 5:00 p.m. AST on Sunday, Erin’s center was positioned approximately 275 miles northwest of San Juan, Puerto Rico, tracking west-northwest at 13 mph. Although no longer directly affecting the area, the storm’s outer bands are still delivering heavy rainfall, dangerous marine conditions, and life-threatening surf along coastal areas.

Spirit Airlines appeared to fly through Hurricane Erin on Monday as a statement from the airline claimed the plane "followed instructions"

While the category 4 storm is not expected to make landfall on the U.S. east coast, it will have an impact nonetheless. Dangerous high surf and rip currents are expected from Florida to New England throughout the week.
