Lifeguards and fire rescue crews in Hollywood Beach are on alert as red warning flags and safety signs go up, urging visitors to avoid the water altogether.

Hurricane Erin is moving east of the U.S. coast and will bring strong waves and rip currents to Florida's east coast – and it comes as the National Center is eyeing two more tropical waves in the Atlantic.

Hurricane Erin is expected to run parallel to the Eastern Seaboard, posing threats of life-threatening surf and dangerous rip currents to areas like New Jersey, New York and Long Island throughout the week. Florida’s small businesses are paying the price.

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.
