Hurricane Erin is well offshore, but it will bring 'dangerous' rip currents, waves as large as 10-feet to Brevard. When to expect the roughest waters.

Much of North Carolina’s Outer Banks region is under a tropical storm watch with Hurricane Erin expected to skirt the area Wednesday through Thursday, according to the National Hurricane Center.

Rip currents off the coast of New Hampshire last week resulted in dozens of rescues on Hampton Beach. Lifeguards at the popular summer destination made 144 rescues over six days, the New Hampshire State Beach Patrol said. There were 51 rescues on Aug. 12 alone.

“Rip currents can be killers,” a webpage on rip currents provided by Manchester-by-the-Sea reads. “The United States Lifesaving Association estimates that the annual number of deaths due to rip currents on our nation’s beaches exceeds 100. Rip currents account for over 80% of rescues performed by surf beach lifeguards.”
