King tides are bringing dangerous surf, strong winds and a coastal flooding threat to Central Florida beaches, with several weather alerts in effect in Volusia County.

WFTV reported that a flood warning, coastal flood warning, wind advisory and high surf advisory were in place in the county. Some alerts could remain active for several days as conditions develop.

Tides Monday morning could exceed five feet, raising the risk of water reaching low-lying coastal areas. Coastal flooding can occur without rainfall when elevated tides push water farther inland.

In Volusia County, waves were reaching 6 to 10 feet, creating hazardous conditions for swimmers and surfers. County officials urged residents and visitors to avoid dangerous beach areas, watch posted warnings and follow local instructions.

Beach conditions had already prompted closures to the south. Brevard County officials closed all beach access points Sunday because of rough surf and strong winds, according to WFTV.

King tides occur at certain times of year when the gravitational forces of the moon, sun and Earth align, producing higher-than-usual water levels. The conditions arrive shortly after Volusia County introduced a beach flag warning system intended to help visitors recognize ocean hazards.
