Horry County is home to Myrtle Beach and the Grand Strand — one of the most visited coastal resort destinations in the US. Florence in 2018 caused catastrophic flooding across the county with the Waccamaw River cresting at record levels. The county's Atlantic coastline and barrier island communities face direct hurricane exposure, and its tourist economy makes evacuation logistics particularly complex.

// Preparedness Recommendations

  • Evacuation routes inland should be identified in advance.
  • Store at least 72 hours of food and water.
  • Elevate critical belongings above flood level.
  • Have backup power ready in case of grid failure.

// Recommended Supplies

Essential gear for power outages, severe weather, and emergency situations in your area.
