King tides and steady onshore winds are causing coastal flooding in parts of South Florida, with water levels expected to rise over low-lying roads and sidewalks during high tide cycles through Monday. A Coastal Flood Warning is in effect for coastal Broward and Miami-Dade counties, and a more severe Coastal Flood Warning is in effect for the Upper Keys.

Why It Matters

Rising salt water is expected to inundate driveways, sidewalks, and low-lying roadways near the shore, and water in storm drains may block fresh water from clearing the streets.

Key Facts

  • King tides have returned to South Florida, bringing water levels higher than any average day.
  • The seasonal high tides are driven by the alignment of the Earth, the Sun, and the Moon during spring and autumn.
  • Steady winds pushing water toward the coast will cause flooding one to two hours before and after morning and afternoon high tides.
  • A standard Coastal Flood Warning is in effect for coastal Broward and Miami-Dade.
  • A more severe Coastal Flood Warning is in effect for the Upper Keys (Cayos Altos).
  • Water is expected to rise briefly over low-lying roads, driveways, and sidewalks near the shore.
  • Moderate to significant flooding is expected to persist through Monday due to increasing winds and intermittent rains.
  • Salt water entering storm drains can prevent fresh water from clearing the streets, worsening street flooding.
  • Drivers are advised never to drive through flooded streets because water depth can be deceptive and damage or immobilize vehicles.
