A patchy bloom of the Florida red tide organism, Karenia brevis, persists in Southwest Florida from Pinellas to Lee counties.
Over the past week, Karenia brevis was observed at background to very low concentrations in three samples collected from Pinellas County; background concentrations in two samples collected from Manatee County; background to medium concentrations in twenty samples collected from Sarasota County; background to medium concentrations in seven samples collected from Charlotte County; and background to medium concentrations in eighteen samples collected from Lee County.
Additional samples collected throughout Florida over the past week did not contain K. brevis.
Forecasts for Southwest Florida by the USF-FWC Collaboration for Prediction of Red Tides predict net southern movement of offshore surface waters, net northern movement of inshore surface waters, and southern, onshore movement of subsurface waters from Pinellas to northern Monroe counties over the next three days.
This information, including maps and reports with additional details, is also available on the FWRI Red Tide website. The website also provides links to additional information related to the topic of Florida red tide including satellite imagery, experimental red tide forecasts, shellfish harvesting areas, the FWC Fish Kill Hotline, the Florida Poison Information Center (to report human health effects related to exposure to red tide), and other wildlife related hotlines.
