Forecasters are sticking with predictions that Tropical Storm Debby will dump extreme amounts of rain on parts of South Carolina through Friday.

Heavy rain and storm surges continue to deluge Charleston and other coastal areas of the state. More than 10 inches of rain had fallen along the coast over the last two days, the National Weather Service reported.

The storm’s track is expected to move slowly toward the east and north on Wednesday, according to the National Hurricane Center. It will drift off Georgia’s coast early Thursday and then move inland later in the day for a repeat assault on South Carolina.

The hurricane center estimates three to six inches of rain could fall on the Upstate through Friday. Periods of heavy rain will likely result in areas of flash and urban flooding, with river flooding possible.

Here are tips from state officials, area emergency responders, and the Red Cross on staying safe during the storm. 

Flooding in low-lying areas is possible

Officials advise residents to avoid floodwaters that could be contaminated with harmful chemicals, sewage, and debris, which pose serious health risks. Motorists should not attempt to drive through floodwaters.

In heavy rain, watch for trees with loose branches and be sure to secure loose items outside

Be ready for emergencies

Josh Hawkins, director of Anderson Emergency Services, advises Upstate residents to stock up on three days’ worth of supplies if necessary and have ample water, non-perishable food items, flashlights, batteries, and a battery-powered radio ready to use. He also said it’s wise to prepare a go-kit, especially if evacuation is necessary. “Don’t forget to include essential medication and diapers in your supplies,” he added.

Duke Energy Carolinas Jason Holifield, communications director said planning before a storm land is important.  

• Have a plan for moving your family – especially the elderly or people with special needs
• Make sure cell phones and other electronics are fully charged. Consider investing in portable chargers.

• Get cash in case ATMs are not working or banks are closed.
• Fill your car with gas or fully charge an electric vehicle.
• If you have an alternative power source such as a generator, make sure you know how to operate it safely.
• Have an emergency kit with non-perishable food; a manual can opener, disposable plates, cups, and utensils, a first-aid kit, medications, a flashlight and spare batteries, and a non-electric clock.

In case of evacuations, Mike Leach, director of the Department of Social Services, said it is important to bring documents such as homeowner or rental verification, insurance information, identification, blankets, and sleeping bags.
