(AP) -- Flood warnings have been issued for parts of Florida's Atlantic coast experiencing annual "King tides."
The National Weather Service says flooding is expected along the St. Johns River and South Florida's coastline through Friday.
King tides bring the year's highest tides each fall. Scientists say they're inching higher because of rising sea levels.
According to the Miami Herald offshore winds from Hurricane Nicole are causing waters to flood some low-lying areas more than expected.
TCPalm.com reports beaches with significant erosion and damage to dunes from Hurricane Matthew are especially vulnerable this year.
The Palm Beach Post says flooding was curb-deep in some West Palm Beach streets Thursday morning. The Post reports last year's tides flooded Boca Raton and Delray Beach yards, enabling fish to swim there.
