Core Event: Coastal Flood Warning and King Tide Impacts (Oct 26-28)
A coastal flood warning covering Miami-Dade, Broward, Palm Beach, Martin, St. Lucie, Indian River and the upper Florida Keys was in effect beginning Monday, October 26 and running through at least Wednesday, October 28. The National Weather Service in Miami warned of “major coastal flooding” across portions of the Atlantic coast and issued a concurrent wind advisory. Strong northeast winds (20-25 mph with gusts up to 40 mph) combined with exceptionally high tides—referred to as king tides—pushed salt water onto streets, parking lots and low-lying homes.
Background & Context
King tides occur when the moon is near perigee during a new or full phase, producing the highest astronomical tides of the year. The October full moon, described by NOAA as a “Hunter’s Moon,” amplified tidal heights along Florida’s east coast. Officials have warned that repeated king-tide events are part of a seasonal pattern that can exacerbate coastal erosion and flooding.
Data & Statistics
- Geographic scope: Coastal flood warning extended from Palm Beach County south to the upper Florida Keys, including West Palm Beach, Fort Lauderdale, Miami and Homestead.
- Wind advisory: Sustained winds of 20-25 mph with gusts up to 40 mph were forecast for Monday-Tuesday.
- High-tide timings: Monday 9:06 p.m.; Tuesday 9:47 a.m. and 9:51 p.m.; Wednesday 10:35 a.m. and 10:38 p.m.
- Advisory expirations: Coastal Flood Warning for Palm Beach County until 8 p.m. Wednesday, October 28; for Indian River, St. Lucie and Martin counties until 2 a.m. Thursday, October 29.
- Wave heights: Forecasted surf of 8-13 ft along the Palm Beaches, with 7-11 ft possible on the Treasure Coast.
- Rip-current risk: High risk maintained through Wednesday evening for Palm Beach County and through late Wednesday night for neighboring counties.
Official Statements & Responses
The City of Miami’s emergency management team advised residents to avoid driving through floodwater, to clean any skin contact with salt water using soap and hot water, and to employ sandbags or other flood-mitigation measures for vulnerable properties. Local law-enforcement agencies, including the Martin County Sheriff’s Office, deployed high-water rescue vehicles to assist motorists stranded on flooded roads such as SW Dyer Point Road and SW 34th Street.
On-the-Ground Reports
Residents described the inundation as “pretty bad” and noted damage to vehicles and limited outdoor activity. The flooding forced some drivers to seek higher ground, while others continued jogging despite standing water. Business owners along the Hollywood Beach Broadwalk reported sandbagging and boarding up windows in preparation for the tide.
Conflicting Reports & Gaps
Sources differ on the precise timing of the highest tides. CBS12 lists specific high-tide peaks for Monday, Tuesday and Wednesday, whereas another article references a broader “peak tide period” without exact times. Additionally, the wind advisory’s end time varies between sources. No source provides definitive data on the total volume of water displaced or long-term erosion impacts.
What’s Next
The scheduled Coastal Flood Warning for Palm Beach County remains in effect until 8 p.m. Wednesday, October 28, and for Indian River, St. Lucie and Martin counties until 2 a.m. Thursday, October 29. A high-risk rip-current advisory continues through the same period. Forecasts indicate additional king-tide peaks later in the week, with wind gusts potentially reaching 35-40 mph, which could sustain flooding conditions in low-lying neighborhoods. Residents are urged to monitor updates from the National Weather Service and local emergency management agencies.
