Hurricane Erin is forecast to impact millions despite not being expected to make landfall on the U.S. mainland.
The outer bands of the storm are expected to bring poor weather conditions to the North Carolina coast by this evening, where a state of emergency has been declared.
Swimming at most East coast beaches is being advised against due to life threatening surf and rip currents.
As of the 10 a.m. Wednesday morning advisory from the National Hurricane Center, Erin had maximum sustained winds of 110 miles-per-hour and was about 365 miles south-southeast of Cape Hatteras, North Carolina.

Forecasters at the NHC also continue to watch two tropical waves in the Atlantic.
Near the Leeward Islands in the Tropical Atlantic:
A tropical wave located over the central tropical Atlantic continues to produce a broad area of disorganized showers and thunderstorms. Environmental conditions appear conducive for gradual development of this system, and a tropical depression could form late this week or over the weekend while it moves near or to the north of the northern Leeward Islands.
Eastern Tropical Atlantic:
A tropical wave located to the southwest of the Cabo Verde Islands continues to produce a concentrated area of showers and thunderstorms. Environmental conditions appear marginally favorable for additional development over the next day or so while the system moves westward at around 15 mph and a short-lived tropical depression could form. By the end of the week, environmental conditions are expected to become unfavorable for further development.
There are no current tropical threats to the northern Gulf coast.
