Flood Warning System

Flood warnings are forecasts of impending storms and are broadcast to the public by the National Oceanic Atmospheric Administration (NOAA) Weather Radio, commercial radio, TV stations, and local emergency agencies. The most serious threat of general flooding is during hurricane season (June through November). The following local radio and TV stations carry advisories for our area:

Weather Alerts

If a storm is threatening the area, listen to local radio stations for emergency instructions. You should keep a NOAA weather radio at frequency 162.425 or 162.550 MHz, and set the SA.M.E. code for St. Johns County to 012109. By listening to weather alerts, you’ll have enough warning time to protect your property or evacuate. A hurricane watch warns that a hurricane is expected within 36 hours, while a hurricane warning warns a hurricane is expected in 24 hours or less.


You can also register with the St. Johns County Sheriff’s Office (SJCSO) for CodeRed, a telephone emergency notification service based on geography. In the event of an emergency in your area, the SJCSO will use CodeRed to inform you of an evacuation notice or other emergencies. To register for CodeRed, call the St. Johns County Sheriff's Office at 904-810-6690.
