Overview
- The National Weather Service on Thursday issued high surf and high rip current advisories for coastal Palm Beach, Indian River, St. Lucie and Martin counties with specific effective windows for each area.
- The Treasure Coast high surf advisory runs from Thursday 8 a.m. to Saturday 4 a.m., with a high rip current risk from 8 a.m. Thursday through late Friday night and Palm Beach County’s rip current risk in effect from Thursday night through Sunday morning.
- Forecasters expect large breaking waves of about 4 to 8 feet and powerful, fast-moving rip currents that can pull even strong swimmers offshore, and they advise against entering non‑lifeguarded waters during the advisory periods.
- The timing coincides with the weekend’s Harvest full moon and King Tide cycle, which will push tides higher than normal and raise the chance of minor coastal flooding in vulnerable low-lying streets and properties.
- Local authorities urge people to swim only at lifeguarded beaches, obey posted flags, keep boats sheltered because seas may reach 7–10 feet, and move vehicles or valuables from low areas to reduce flood damage.
