Travelers to Myrtle Beach are being asked to avoid driving to the area as flood conditions worsen and car travel across the larger region continues to be hit and miss. 

The Myrtle Beach International Airport is open with no flight disruptions, so officials recommend arriving by air, said Julie Ellis, spokeswoman for the Myrtle Beach Area Convention and Visitors Bureau.

"The waters are still rising and the flooding is unpredictable, so we can’t guarantee a safe route, and the limited number of open routes are needed for local and emergency traffic," Ellis said. 

Last week, officials encouraged drivers to arrive in Myrtle Beach from the south, up U.S. Highway 17. But by Sunday afternoon, concerns of flooding in the Georgetown area had risen, and Highway 17 through Georgetown was reduced to one lane of traffic each way near the Waccamaw River. 

Generating about $7 billion a year, Myrtle Beach’s tourism industry is the state's largest, and while it's eager for visitors, officials have been careful to warn them of flood conditions, Ellis said.

More than 30 hotels are offering discounted rates to people displaced by the floodwaters. Rooms are being offered for as little as $25 a night.

A handful of attractions are also offering free or discounted admission to people displaced by the storm. A list of the special offers can be found on the Myrtle Beach Area CVB's website.

Interstate 95, the nation's main east coast highway, reopened throughout the Carolinas on Monday after more than a week of closures due to Hurricane Florence flooding.

However, hundreds of other roads remain closed in the Carolinas as flooding continues 10 days after Hurricane Florence made landfall near Wrightsville Beach, N.C. That included 415 roads closed in North Carolina and 151 road and bridge closures in South Carolina as of Monday.

Interstate 40 remained closed Monday from Wilmington, N.C., to Exit 385, and the North Carolina Department of Transportation was urging motorists to avoid 11 southeastern counties. That's down from 17 counties on Friday.

The NCDOT urged drivers to not go around barricades, saying: "If a road is closed, it is closed for a reason."

South Carolina motorists were being urged to use SCDOT’s 511 mobile app or to call 511 for current travel conditions.
