South Florida’s east coast is under a coastal flood warning as king tides, gusty winds, and passing downpours combine to push seawater over seawalls and into streets from Palm Beach County down to the Florida Keys. Forecasters warn that coastal flooding could reach its peak as tides cycle through midweek.
Coastal Flood Warnings and Wind Advisories Span Palm Beach Down to Key West
Coastal flood warnings extend from Palm Beach County down to the upper Florida Keys, encompassing West Palm Beach, Fort Lauderdale, Miami, and Homestead, with a separate coastal flood advisory covering the middle and lower Florida Keys. The National Weather Service issued a stark caution regarding the inundation. Salt water can damage cars, and remember to avoid driving through flooded roadways!
the service said.

At the same time, a wind advisory covers metro and coastal areas of Miami-Dade, Broward, and Palm Beach Counties. Northeast winds are sustaining speeds of 20 to 25 miles per hour with frequent gusts reaching up to 40 miles per hour. Forecasters warn that these strong gusts could cause power outages and travel delays.
Fort Lauderdale and Miami Streets Submerge as High Tides and Onshore Winds Collide
Streets in Fort Lauderdale and Miami went underwater as astronomical high tides met persistent onshore breezes. In South Port Everglades, water levels surged to 2.25 feet above normally dry ground on Monday, surpassing records set by Hurricane Nicole in 2022. Similar inundation pushed water across Collins Avenue near 52nd Street in Miami Beach, onto a parking lot along the 79th Street Causeway in North Bay Village, and across the Hollywood Beach Broadwalk where crews installed orange barriers to block debris.

In Fort Lauderdale neighborhoods like River Isles, water rose rapidly as high tide approached. It was rising fast. We just went for a walk around the block, and on the way back here we already had to take a little bit of a different route just to get back to where we were 30 minutes ago,
Tommy Krcmaric said.
City officials in Fort Lauderdale explained that municipal pumps cannot clear the streets because ocean levels remain exceptionally high. Pumping water into waterways already swollen by the tide is ineffective, leaving runoff trapped in the streets until the tide recedes.
Farther north, king tide flooding affected Martin County parks, boat ramps, and residential enclaves. Along Southwest Dyer Point Road in Palm City, passing vehicles pushed waves toward homes. Terresa Baldwin, an eight-year resident of the neighborhood, described unprecedented conditions around her property. We had water coming from the back and the front,
Baldwin said.
Martin County and Palm Beach County Communities Face Waterlogged Roads and Facility Closures
Farther north, king tide flooding affected Martin County parks and residential enclaves. Along Southwest Dyer Point Road in Palm City, rising water submerged roads.
The Martin County Sheriff’s Office placed high-water rescue vehicles on standby along Southwest Dyer Point Road, Southwest 34th Street, and Cornell Avenue. Meanwhile, the Juno Beach Pier closed indefinitely after pounding surf and strong winds popped out more than a dozen deck panels. In Boca Raton, rising water reached a Cub Scout pack’s campsite at Spanish River Park.
Astronomical Moon Alignment and Pressure Gradients Drive the Coastal Surge
The flooding is driven by a convergence of seasonal astronomical forces and regional weather patterns. King tides occur when higher-than-normal tides coincide with new or full moons, particularly when the moon is at its perigee. October’s full moon peaked early on October 26.
Meteorologists note that a broader atmospheric setup is amplifying the tidal impact. High pressure positioned over western North Carolina and low pressure over the southern Bahamas are squeezing the air, generating strong northeasterly winds that trap water in bays and waterways.
Emergency Guidance and Projected Timelines Through Midweek
Local authorities across South Florida urge residents to exercise caution. The town of Boynton Beach warned motorists never to underestimate the depth of floodwater and advised drivers to consider alternate routes. In Boynton Beach, officials made free self-service sandbags available at Harvey E. Oyer Jr. Park.
According to forecasts from the South Florida Water Management District, the current king tide period is expected to continue through November 12.
