Residents and visitors are advised to take the following precautionary actions:
- If driving, be alert for low visibilities and slippery roads in heavy rain;
- Slow down where water is ponding on the road;
- Turn Around, Don’t Drown. Avoid walking or driving through flood waters. Just 6 inches of moving water can knock you down, and 2 feet of water can sweep your vehicle away;
- Avoid camping, parking, or hiking along streams, rivers, and creeks during heavy rainfall. These areas can flood quickly and with little warning;
