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.
So what's the latest on Erin? Erin weakened slightly overnight and Tuesday morning and is now a strong Category 2 storm with maximum sustained winds of 110 mph. A major hurricane is one that's a Category 3 or higher, with sustained winds of at least 111 mph.
What impacts could Hurricane Erin have on Florida?
Florida’s east coast faces a significant risk from Hurricane Erin, including dangerous surf and life-threatening rip currents, according to Michael Brennan, director of the National Hurricane Center.
Swells generated by the storm could produce wave heights of 20 to 30 feet—and possibly up to 50 feet near its center. These swells are expected to impact much of Florida’s coastline, increasing likelihood of life-threatening rip currents to Florida's coast.
Along Northeast Florida beaches, Surf heights could reach 7 to 10 feet between August 19 and 21. Farther south, along east central Florida, waves are forecast to peak at 9 to 11 feet, with some reaching up to 14 feet on August 20, according to the National Weather Service in Melbourne.

“This is going to make for very dangerous marine conditions across all of the western Atlantic and increase the risk for dangerous and life-threatening surf and rip current conditions across almost the entire US East Coast,” Brennan said.

Jacksonville: 'Stay out of the ocean'
In Northeast Florida, ocean breakers of greater than seven feet are expected Tuesday through Thursday, according to the Weather Service, with the peak wave height around high tide on Wednesday. Minor coastal and tidal flooding is possible with "at least moderate beach erosion," said NWS meteorologist Angela Enyedi. Moderate beach erosion is possible during the early Wednesday evening high tide.
The National Weather Service is advising everyone, including surfers, to 'stay out of the ocean' as High Rip Current risk will impact all local beaches with a High Surf Advisory in effect until Thursday with breakers reaching 5 to 8 ft today and 7 to 11ft Wednesday.

How is Hurricane Erin impacting Jacksonville this week?
Here's a breakdown for the week:
Tuesday: Seas will build to 6-8 feet offshore after midnight and to Caution levels of 4-6 feet near shore this evening, building further to 5-7 feet during the predawn hours on Tuesday. Deadly surf conditions will begin on Tuesday all along the coast, with breaker heights building to 6-8 feet by the afternoon hours at Northeast Florida beaches
Wednesday: Seas will peak in the 8-11 foot range near shore on Wednesday and Wednesday night, while seas offshore peak in the 11-14 foot range on Wednesday. A high surf advisory will likely be issued for the Northeast Florida beaches from Tuesday through at least Thursday night, with breakers peaking in the 9-11 foot range on Wednesday.
Thursday: Expect seas ranging from 6 to 9 feet, Shashy said, and to remain elevated through the weekend.
What is a rip current?
Rip currents are powerful channels of water flowing quickly away from shore, which occur most often at low spots or breaks in the sandbar and in the vicinity of structures such as jetties and piers.
Rip currents form when incoming waves create an underwater sandbar. The waves push more water between the sandbar and the shore until it collapses and the water rushes back to the sea through a narrow gap, where it starts to spread out. But they can be difficult to see when you're in the water as the ocean over them can still be smooth.
Entering the surf is strongly discouraged. If caught in a rip current, relax and float. Don`t swim against the current. If able, swim in a direction following the shoreline. If unable to escape, face the shore and call or wave for help.

North Carolina braces for Hurricane Erin. Watches issued
Several watches associated with Erin have been issued for North Carolina:
Storm surge watch: Cape Lookout to Duck, North Carolina
Tropical storm watch: Beaufort Inlet to Duck, North Carolina including Pamlico Sound
The storm’s rapid intensification prompted increased emergency measures in North Carolina. The Outer Banks — a popular summer vacation spot — are under a state of emergency. Officials mandated evacuations for Hatteras Island, ordering visitors to leave by 10 a.m. Monday, Aug. 18, and residents by 8 a.m. Tuesday, Aug. 19, as forecasters warned of life-threatening rip currents, large swells, coastal flooding and road washouts.
The hurricane center warned storm surge could cause the water to rise 2 to 4 feet above dry ground along the Outer Banks as Erin moves north.

Tropical storm conditions and coastal flooding are possible in the North Carolina Outer Banks beginning late Wednesday or Wednesday night where Tropical Storm and Storm Surge Watches are in effect. Interests in along the U.S. Mid-Atlantic and southern New England coasts and on Bermuda should also monitor the progress of Erin as strong winds are possible Thursday and Friday.
