King tide hazards remain in Dorian’s wake.

With seas up as much as 14 feet, king tides gorged on Hurricane Dorian’s winds and rains and swelled up over coastlines, drowning already-vulnerable areas in South Florida.

In Fort Lauderdale, the king tides Tuesday were about 2.5 feet higher than normal, city spokesman Chaz Adams said in an email.

“That’s a substantia­l tide likely augmented by the effects of Hurricane Dorian,” Adams wrote. That made the tide about a foot above the threshold at which lowlying areas of Fort Lauderdale flood, he said.

In Palm Beach County, the ocean surged up over the docks at the Palm Beach Yacht Club and waterfront restaurant­s, such as Two Georges Waterfront Grille in Boynton Beach. The Earman River along the Intracoast­al Waterway flooded in Lake Park.

Standing water submerged West Palm Beach streets along the 1500 block of North Flagler, Eighth Street and North Flagler, and Banyan Boulevard and Flagler Drive.

Miami-Dade saw its share of wade-worthy waters, with cars surfing through water-logged roads near Northeast 79th Street and 10th Avenue on Tuesday afternoon. The ocean crept up over the seawall into the parking lot at the Haulover Marina. Miami has floodprone spots in Shorecrest, Fairview, Brickell and Coconut Grove.

This week, high tides start about 1 p.m. and 1 a.m. on South Florida beaches between Miami-Dade and Palm Beach County. Low tides start about 7 a.m. and 7 p.m.

Low-lying streets in Fort Lauderdale were still submerged Wednesday. The road right along the Intracoast­al near the Oakland Park Bridge near A1A also flooded.

“We can expect to continue to see flooding on low lying streets as tides continue to remain strong in the wake of Hurricane Dorian,” Adams in an email. “This will be exacerbate­d by any rainfall events that occur concurrent with high tide, particular­ly in areas with tidal valves.”

A coastal flood advisory is in effect for the Atlantic coast through Thursday. One to three feet of water above ground is possible in coastal Palm Beach County, according to the National Weather Service. Two feet of water above ground is possible in Broward and Miami-Dade counties, NWS says.

The combinatio­n of Hurricane Dorian and the king tides increases wave action, leading to increased swell along the coast. Coupled with the king tides, it increases the chance for flooding, according to Paxton Fell, a NWS meteorolog­ist.

“Even though Dorian is well to the north, it takes a little longer for marine impacts to subside than land impacts,” Fell said. “We peaked with king tide and high tides earlier today, so with everything starting to diminish, hopefully we’ll be able to start weaning down the flood advisories and monitor the next high tide cycle to see what it’s doing, and if it’s going back to normal.”

The floods affect docks, piers, and some waterfront and low-lying streets.

King tides, the colloquial term for the highest high tides of the year, happen every year from September to November. The tides started peaking last week as Hurricane Dorian menaced the coast, and were expected to die down this week.

For the rest of this year, king tides are predicted to peak:

■ Sept. 26 to Oct. 3

■ Oct. 25 to Oct. 31

■ Nov. 24 to Nov. 28.
