Effective: Wed October 8, 2025, 2:33 PM
Expires: Sun October 12, 2025, 4:00 AM

* WHAT...For the High Rip Current Risk, dangerous rip currents. For the Coastal Flood Advisory, minor coastal flooding. For the Coastal Flood Watch, significant coastal flooding possible. * WHERE...Coastal Volusia, Coastal Indian River, Coastal Saint Lucie, Coastal Martin, Mainland Northern Brevard, Northern Brevard Barrier Islands, Mainland Southern Brevard and Southern Brevard Barrier Islands Counties. * WHEN...For the High Rip Current Risk, through late Saturday night. For the Coastal Flood Advisory, until 8 PM EDT Thursday. For the Coastal Flood Watch, from Thursday evening through late Saturday night. * IMPACTS...Some roads may be closed. Low lying property including homes, businesses and some critical infrastructure may be inundated. Shoreline erosion may occur. Rip currents can sweep even the best swimmers away from shore into deeper water.

Conditions favorable for coastal flooding are expected to develop. Coastal residents should be alert for later statements or warnings and take necessary actions to protect flood-prone property. Rip currents are powerful channels of water flowing quickly away from shore, which occur most often at low spots or breaks in the sandbar and in the vicinity of structures such as jetties and piers. Heed the advice of lifeguards, beach patrol flags and signs. Entering the surf is strongly discouraged. If caught in a rip current, relax and float. Don't swim against the current. If able, swim in a direction following the shoreline. If unable to escape, face the shore and call or wave for help.

The times presented here are based upon the solunar theory, which is the idea that the movements of fish and other animals are affected by the location of the sun and moon. The major periods are believed to be the times of the greatest animal activity and occur when the moon is directly overhead or underfoot (lunar transits). The minor periods also see increased activity and occur when the moon is rising or setting. The strongest activity occurs during full or new moons, and the weakest during quarter or three quarter moons. This is indicated by the Action Rating.
