Hurricane Update


Final Update

Before Hurricane Idalia ever made landfall in South Carolina, DHEC’s team of dedicated employees began to prepare for the storm’s anticipated impact. 


DHEC is here to help our state's residents. You can use these hotlines for DHEC specific needs.

  • Dams Emergency Response: 803-898-1939
    Call if you have an emergency that needs immediate attention at a DHEC regulated dam
  • Mold: 888-815-3509
    While DHEC doesn't perform remediation for mold, residents can receive information about storm-related mold issues
  • Private Well: 888-761-5989
    Provides help to private well owners

Stay Safe After the Storm


Porous materials — wood, drywall, carpet, mattresses, fabrics and furniture made of particle board — soak up water like a sponge. Items that cannot be dried thoroughly within 24-48 hours of getting wet are much more difficult to disinfect and may need to be replaced to prevent mold growth. See Indoor Mold After a Weather Event for information to help residents make decisions regarding mold in homes and workplaces.

Private Wells

Wells should be inspected after the storm for damage and any plug or covering on casing vent should be removed. For specific guidance, see Private Wells: What to Do Before and After Storms. If your private well was flooded and you have questions concerning testing, call the Private Well Hotline at 888-761-5989

Food Safety

Illnesses caused by bacteria in food or water can be among the greatest problems caused by a hurricane or flood. Both loss of power and flooding pose a threat to your water and food supplies. In high water and flooding, food, water and utensils can be contaminated with bacteria, sewage and/or chemicals. In a power outage, frozen and refrigerated foods can be contaminated with bacteria that will grow once the temperature of the food gets above 40°F. All of this can seriously affect the health of you and your family. To reduce the risk of contamination we offer these tips

Use Safe Water

It's important you take steps to prevent illness from unsafe water. DHEC provides tips that private well owners can take before and after a storm. If you are unsure about your water supply, use only bottled or stored water until it is determined that the water is safe to drink.

Avoid Floodwater, Beware of Hazards

Floodwater are nothing to play with or to take for granted. Exercise caution. All too often, danger lurks within and beneath floodwater and standing water.

DHEC urges everyone not to use area streams, rivers or the ocean for drinking, bathing, or swimming due to the possibility of bacteria, wastewater or other contaminants. Avoid wading through standing water due to the possibility of sharp objects, power lines or other hazardous debris that might be under the surface.

Follow these steps if you encounter floodwater or standing water.

  • Avoid or limit direct contact.
  • Wash your hands frequently with soap, especially before drinking and eating.
  • Do not allow children to play in floodwater or play with toys contaminated with floodwater.

Turn Around, Don’t Drown!

No matter how harmless it might appear, avoid driving, wading or walking in floodwater. Just 6 inches of moving water can knock you down and one foot of moving water can sweep your vehicle away.

SC MyCoast

DHEC encourages coastal residents affected by Hurricane Ian to report damage to beachfront structures, including seawalls, revetments and dune walkovers using SC MyCoast. Residents using SC MyCoast’s Storm Witness report for the first time will need to register before submitting a report. Registration is quick, easy and free. To report through SC MyCoast, go to

Beach Renourishment, Sand Scraping, Sandbags 

Based on storm damage reports, DHEC may issue targeted emergency orders to local governments to allow property owners along the immediate beachfront to conduct minor renourishment, sand scraping or install sandbags to provide temporary protection to beachfront structures from wave uprush. See Hurricane Idalia Recovery and Requirements to learn more.
