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

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

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.

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.

Hurricane Erin is likely to restrengthen again as it passes east of the Turks and Caicos Islands and the southeast Bahamas on Monday after lashing the Caribbean with damaging winds and flooding rain.

Hurricane Erin weakened to a Category 3 hurricane on Sunday, its outer bands lashing the Virgin Islands and Puerto Rico, as forecasters warned the storm was rapidly growing.

As of 11 AM AST Sunday, the National Hurricane Center reported that Erin’s center was located about 200 miles northwest of San Juan, Puerto Rico, and 240 miles east of Grand Turk Island. The hurricane is packing maximum sustained winds of 125 mph, making it a Category 3 storm. Its minimum central pressure is estimated at 946 millibars.

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.
