Current ConditionsA bloom of the Florida red tide organism, Karenia brevis, persists in Southwest Florida and currently extends along ~130 miles of coastline. Observations of >1,000,000 K. brevis cells per liter (“high” concentrations) continue to occur at coastal and inshore sites from Manatee to Collier counties, although cell concentrations decreased in parts of Manatee, Sarasota, Lee, and Collier counties relative to last week. Coastal currents important for transporting cells of K. brevis continue to alternate between predominantly northern or southern flow. K. brevis was observed in Pinellas County (for the second week in a row), and additional sampling there and in Hillsborough County indicated that concentrations were below 100,000 cells per liter in all samples examined. More specific details are provided below.
Fish KillsOver the past week, reports were received for multiple locations in Pinellas, Manatee, Sarasota, Charlotte, Lee, and Collier counties. More detailed information is available at /fishkill.
Respiratory IrritationRespiratory irritation was reported over the past week in Pinellas County, Manatee County, Sarasota County, Lee County, and Collier County. For additional information, view the southwest coast report .
ForecastForecasts by the USF-FWC Collaboration for Prediction of Red Tides for Pinellas to northern Monroe counties predict variable movement of surface waters with net northern transport expected close to shore, and net southeastern transport of subsurface waters over the next three days.
