Erin is a large hurricane and is expected to grow "substantially in size" as it moves over the western Atlantic this week, according to the Hurricane Center. Hurricane-force winds extend outward up to 80 miles from the center, and tropical-storm-force winds extend outward up to 205 miles.

South Florida is not forecast to see direct impacts from Hurricane Erin, but rip currents and surf up to 6 feet, especially along Palm Beach, are likely.
