Do you think flooding from coastal tides is getting worse in your area?
Rising waters flooded parking lots at area marinas in southeast Louisiana, and fishermen launched boats despite the flooding. The National Weather Service has issued coastal flood advisories for several days as the water continued to rise.
Why it matters
Flooding at coastal marinas and launch areas affects boat access and local waterfront activity across the state's southeast coast. The advisories underscore how tide and wind conditions can quickly disrupt low-lying shoreline communities.
Measured depths at Rigolets Marina dropped from about 10 inches to four inches by mid-afternoon, while east-southeast winds near 15 miles per hour sustained the high water. The source does not say whether the water will recede fully before the next tidal cycle.
The players
National Weather Service
The National Weather Service is the federal agency responsible for issuing weather forecasts and watches, warnings, and advisories across the United States.
The details
Strong tides combined with persistent east-southeast winds to raise water levels, with the coastal flooding peaking Monday morning. Water covered the launch area at a marina, and Lake Catherine Island Marina posted photos showing the high water.
Timeline
Monday: Coastal flooding peaked and fishermen launched boats despite the water.
Past several days: National Weather Service coastal flood advisories remained in effect.
Tonight through the end of the week: Tidal range is expected to return toward typical levels.
Seasonal Patterns
King tides, the higher astronomical tides that occur at certain points in the lunar cycle, recur each year along the Gulf Coast and fall within the framework the National Weather Service uses for coastal flood advisories. This event follows that seasonal pattern, with wind adding to tidal height along southeast Louisiana's shoreline.
Boaters and anglers planning to use southeast Louisiana marinas should check current water levels before launching, since parking and launch areas may remain flooded. Residents in low-lying coastal areas such as Shell Beach should monitor National Weather Service advisories for updates.
The takeaway
Coastal flooding from king tides and persistent wind can disrupt marinas and low shoreline areas even without major storms. Monitoring tidal forecasts and official advisories helps boaters and residents plan around short-term water rises.
What happens next
Tidal range is expected to return toward typical levels beginning tonight and continuing through the end of the week.
