Hurricane Erin has weakened slightly to a Category 2 hurricane but is forecast to "substantially grow in size" as it moves over the western Atlantic Ocean through the week, according to the National Hurricane Center.
But will Hurricane Erin hit the United States? Will major tourist destinations in the country's southeastern region be impacted by the storms? Here's what to know.
What to know about Hurricane Erin
USA TODAY reports Hurricane Erin was located about 655 miles south-southeast of Cape Hatteras, North Carolina, with maximum sustained winds near 105 mph with higher gusts, per a 2 p.m. ET advisory from the hurricane center Aug. 19.
The hurricane's center was expected to pass to the east of the Bahamas on Aug. 19, and then move over the western Atlantic between the U.S. East Coast and Bermuda on Aug. 20 and Aug. 21.
However, Erin's strength could still fluctuate before it finally begins to wind down later in the week, according to the center's forecast.
Big waves and rough surf are expected along the Atlantic Coast from Central Florida to Canada. An expected storm surge and waves over 10 feet have prompted evacuations on at least two of the islands along North Carolina's Outer Banks. Heavy rainfall is also possible on the Outer Banks on Wednesday night into Thursday with potential for 1 to 2 inches and a local maximum of 4 inches.
The National Weather Service is urging people to stay out of the ocean to avoid deadly surf conditions expected through at least Thursday.
A storm surge watch is in effect from Cape Lookout to Duck, North Carolina, which means there is a possibility of life-threatening inundation, from rising water moving inland from the coastline, in the indicated locations during the next 48 hours. The NWS said storm surge in this area could reach 2 to 4 feet.
What category is Hurricane Erin?
Per the NHC, Hurricane Erin has weakened slightly into a Category 2 hurricane but is forecast to "substantially grow in size" as it moves over the western Atlantic Ocean throughout the week.
Erin is expected to become a Category 3 hurricane by Wednesday evening, CNN reported.
Where is Hurricane Erin hitting?
According to NPR, Hurricane Erin is not expected to make landfall in the U.S.
Still, Erin's large and expanding wind fields mean storm-driven waves, coastal erosion and high seas are expected to batter areas of the East Coast, especially along the Outer Banks.

How will Hurricane Erin affect Disney World and other theme parks in Florida?
As of Aug. 20, all Walt Disney World parks and studios remain open under normal conditions. For severe weather updates, visit disneyworld.disney.go.com.
If the National Hurricane Center issues a hurricane warning for the Orlando area within seven days of a guest's scheduled arrival date, they may reschedule or cancel their Walt Disney Travel Co. Disney Resort hotel packages and most room-only reservations (booked directly with Disney). Per the theme park's FAQ page, there will be no cancellation or change fees.
Customers who purchase Disney tickets through a third-party site will still be responsible for any nonrefundable payments and cancellation or change fees assessed by those suppliers.
The policy also applies to Disney's Vero Beach Resort and Disney's Hilton Head Island Resort if a hurricane warning is issued for those destinations, the site states.
Universal Orlando Resort's severe weather policy similarly offers penalty-free rebooking and cancellations for vacation packages, hotel stays and tickets booked directly through Universal in the event of a tropical storm, hurricane warning, or state of emergency declaration within seven days of a guest's arrival. For now, the resort is operating as usual.
SeaWorld Orlando also remains open as of Aug. 20. The park also has a Weather-or-Not Assurance policy for extreme weather that applies year-round and guarantees guests the value of their park admission.
Busch Gardens Tampa Bay and Adventure Island Water Park are also open for regular operating hours.
Are airports closed due to Hurricane Erin?
According to the Federal Aviation Administration, most airports across the southeastern U.S. are operating normally as of Aug. 20. However, airports in Texas, New York, New Jersey and Mississippi are experiencing ground stops, ground delays or departure delays due to thunderstorms and/or winds.
How will Hurricane Erin affect Outer Banks, Myrtle Beach, Hilton Head and other destinations?
Although Hurricane Erin is not forecast to make landfall in the U.S., it is still expected to bring significant impacts to several areas along the East Coast.
The Outer Banks was put under a state emergency order Aug. 19. The hurricane's outer bands are expected to bring worsening weather conditions to North Carolina's coast by the evening of Aug. 20, the hurricane center said.
A tropical storm warning is currently in effect from Beaufort Inlet in North Carolina's Outer Banks to the North Carolina-Virginia border, including the Pamlico and Albemarle sounds. A tropical storm watch has also been issued from the North Carolina-Virginia border to Chincoteague, Virginia.
A storm surge warning is also in place from Cape Lookout, North Carolina, to Duck, North Carolina.
Other major U.S. tourist destinations, such as Myrtle Beach and Hilton Head, South Carolina, are not currently in the storm's projected path. But these areas may still experience "increased surf and hazardous rip currents," per Newsweek.
“Significant” ocean swells are also expected in South Carolina and Georgia, with breaking waves of 6 feet or higher through Wednesday night. Coastal flooding may be possible, but major flooding is not forecast.
Officials are also warning of "life-threatening rip currents" from South Florida to Long Island, and are urging people to stay out of the water, no matter how clear the skies are overhead.
No tropical storm or hurricane watches have been issued for areas outside of North Carolina or Virginia at this time.
