Storm Surge Information
Still wondering, if you should evacuate when ordered to during a hurricane? Storm surge is water that is pushed towards the shore by the force of winds swirling around a storm. Following an elevation survey, the City of Cocoa Beach has installed marking points on stop signs depicting how high the water would rise if the city is hit by a storm surge.
- Yellow: 5 feet above mean high-water level
- Orange: 10 feet above mean high-water level
- Red: 15 feet above mean high-water level
