A bloom of the Florida red tide organism, Karenia brevis, persists in Southwest Florida and extends along ~135 miles of coastline, from northern Pinellas to northern Collier counties, and extends offshore (10 miles or more). A patchy bloom of K. brevis also continues in Northwest Florida. Additional details are provided below.
Over the past week in Southwest Florida, K. brevis concentrations generally decreased in areas of Pinellas, Sarasota, and Charlotte counties and increased in northern Manatee County, parts of Lee County, and northern Collier County. Observations of >1,000,000 K. brevis cells per liter (“high” concentrations) occurred in Pinellas, Manatee, Sarasota, Charlotte, and Lee counties and >15 miles offshore of Sarasota, Lee and Collier counties. In Northwest Florida, K. brevis was observed in Okaloosa, Bay, Gulf, and Pasco counties, with up to “medium” concentrations observed in Gulf County only. Relative to last week, cell counts generally decreased in Bay County.
Fish KillsIn Southwest Florida, reports of fish kills were received for multiple locations in and/or offshore of Pinellas, Manatee, Sarasota, Charlotte, and Lee counties and one location offshore of Collier County. In Northwest Florida, reports of fish kills were received for Walton, Bay and Gulf counties. More detailed information is available at http://myfwc.com/fishkill.
Respiratory IrritationRespiratory irritation was reported in Southwest Florida (in Pinellas, Manatee, Sarasota, and Lee counties) and in Northwest Florida (in Gulf County). For additional information, view the Southwest Coast report and Northwest Coast report .
Forecasts by the USF-FWC Collaboration for Prediction of Red Tides for Pinellas to northern Monroe counties predict net southwestern movement of surface waters and net southeastern transport of subsurface waters for most areas over the next three days. Three-day forecasts for Northwest Florida predict net eastern transport of surface waters and northeastern movement of subsurface waters from Escambia to western Gulf counties.
