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.

RODANTHE, N.C. (AP) — Hurricane Erin chugged slowly toward the eastern U.S. coast Tuesday, stirring up treacherous waves that already have forced dozens of beach rescues days before the biggest storm surges are expected.

Erin’s surf and storm surge could cause erosion along sections of the Florida and East Coast and shapes up as potentially worse for North Carolina’s barrier islands, which are under mandatory evacuation orders ahead of the four feet of storm surge and 20-foot offshore waves Erin is expected to bring.

Hurricane Erin weakened to a category 3 hurricane during the early hours of Aug. 19 as it moves closer to the East Coast, according to the National Hurricane Center.

Hurricane watchers are eying systems in the Atlantic basin. One has a medium chance of developing later this week.

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.

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 Hurricane Center is eyeing two more tropical waves in the Atlantic.
