Direct from FEMA:

Storm surge is often the greatest threat to life and property from a tropical system. It poses a significant threat for drowning and can occur before, during, or after the center of a storm passes through an area. Storm surge can sometimes cut off evacuation routes, so do not delay leaving if an evacuation is ordered for your area. Three to five feet of storm surge are expected.
There is the potential for flooding with this storm. Driving through a flooded area can be extremely hazardous and almost half of all flash flood deaths happen in vehicles. When in your car, look out for flooding in low-lying areas, at bridges and at highway dips. As little as six inches of water may cause you to lose control of your vehicle. Four to eight inches of rain are expected, with 10 inch totals in isolated locations.
If you encounter floodwaters, remember – turn around, don’t drown.
Be familiar with evacuation routes, have a family communications plan, keep a battery-powered radio handy and have a plan for pets. Visit www.ready.govorwww.listo.gov to learn these and other preparedness tips for tropical storms.
Know your evacuation zone and be sure to follow the direction of state, local, and tribal officials if an evacuation is ordered for your area.
If you have a National Flood Insurance Program (NFIP) flood policy, you may be eligible for reimbursement of actions taken to protect your property. Call your NFIP insurance agent to find out more.
Get to know the terms that are used to identify severe weather and discuss with your family what to do if a watch or warning is issued.

Hurricane Safety Steps

Find a shelter by visiting redcross.org or by downloading the free Red Cross Emergency App. The Emergency App also puts real time information about the storm and hurricane safety tips at your fingertips. The app is available in app stores by searching for the American Red Cross or going to redcross.org/apps. You can also follow these safety steps:

Continue listening to local area radio, NOAA radio or TV stations for the latest information and updates.
If your neighborhood is prone to flooding, be prepared to evacuate quickly if necessary.
Follow evacuation orders and do not attempt to return until officials say it is safe to do so.
Head for higher ground and stay there.
Stay away from floodwaters. If you come upon a flowing stream where water is above your ankles, stop, turn around and go another way.
Turn around, don’t drown. If driving, turn around and go another way. If you are caught on a flooded road and waters are rising rapidly around you, get out of the car quickly and move to higher ground. Most cars can be swept away by less than two feet of moving water.
Keep children out of the water.
Be especially cautious at night when it’s harder to see flood danger.
Make sure you have a plan and supplies for your pets. Download the free Red Cross Pet First Aid App for emergency preparedness tips, a pet-friendly hotel locator and an animal hospital locator.

During the storm:

Stay indoors.
Don’t walk on beaches, riverbanks or in flood waters.
Use flashlights in the dark if the power goes out. Do NOT use candles.
Turn off the power and water mains if instructed to do so by local authorities.
Don’t forget your pets. Bring them indoors and maintain direct control of them. Prepare an emergency kit for your pets, including sturdy leashes or pet carriers, food and water, bowls, cat litter and pan, and photos of you with your pet in case they get lost.
