South Florida is under a coastal flood advisory on Monday until midnight because of “high astronomical tides due to the lunar cycle,” according to the National Weather Service.
Forecasters warn of possible flooded streets, worsened by expected rain from thunderstorms. The chance of rain Monday is 60 percent.
In anticipation of extreme high tides, Miami Beach will close the southbound lanes of Indian Creek Drive between 40th and 29th streets during the high-tide periods. Ankle-deep water started swamping the area before 10 a.m.
The expected high tides are: 9:21 a.m. and 9:39 p.m. Monday; 10:12 a.m. and 10:28 p.m. Tuesday; and 11:03 a.m. and 11:18 p.m. Wednesday.
“The tides have been higher than we predicted, so we are taking preventive measures,” said Miami Beach spokeswoman Nannette Rodriguez. “Closing the road ahead of time is better for traffic flow.”
The seasonal high tides combined with Sunday’s supermoon already sent several feet of water into the streets of Miami Beach and Fort Lauderdale beach Saturday night and Sunday morning.
Miami Beach officials were forced to shut down Indian Creek Drive on Saturday night, as well, as water flowed into the roadway. Drivers trying to go south are detoured to Pinetree Drive or Alton.
Rodriguez said the city will continue to work with the state on a solution for flooding on the state-owned road.
Rodriguez said that pumps installed in two of the lowest elevation areas — Alton/West and Sunset Harbour — have helped to reduce problems in those areas.
