According to the National Weather Service, Myrtle Beach is likely to receive significant rainfall from Hurricane Florence starting Thursday. Depending on Hurricane Florence’s path, Myrtle Beach will likely receive anywhere from 10-20 inches of rain, which doesn’t include flooding risk from storm surges, too.

Accuweather reports that residents of the Carolina coastline will likely be “bombarded” with rain and heavy wind from Thursday to Saturday. Though NWS estimates upwards of 20 inches of rainfall along the coastline, Accuweather is estimating closer to 40 inches, which could lead to catastrophic levels of flooding from the coastline inland.

Myrtle Beach is currently classified under “moderate” risk of flooding, according to the NWS.


Myrtle Beach Should Expect Up to Nine Feet of Storm Surges Along the Coastline

National Hurricane CenterMyrtle Beach is likely to experience high storm surges of up to nine feet from Hurricane Florence.

According to the National Hurricane Center, Myrtle Beach is likely to receive anywhere from four to nine feet of storm surges from Hurricane Florence, depending upon the path of the hurricane.

Weather.com says of the expected storm surges: “A destructive storm surge will accompany the eye coming ashore sometime from Thursday night into Friday or Saturday, and coastal flooding may persist through multiple high tide cycles into this weekend east of the center of Florence. Large, battering waves will ride atop this surge. All evacuation orders from local officials should be followed because of this dangerous threat. Significant beach erosion is also likely on the southeastern U.S. coast. Elevated water levels may persist for some time after landfall in areas where onshore winds persist.”

The Weather Channel estimates that storm surges of nine feet could cause floods that are so high they might cover the entire first floor of buildings.
