Southwest Region: A bloom of Karenia brevis, the Florida red tide organism, persists in southwest Florida, with the highest concentrations detected this week offshore of Sarasota County and in the Pine Island Sound system (Lee County). Low to medium concentrations were also detected alongshore from Sarasota through Lee counties and very low to low concentrations were detected alongshore and offshore of northern Monroe County. Very low concentrations were also detected offshore of the lower Florida Keys (Monroe County).
Bloom Boundary: The red tide currently affects approximately 100 miles of coastline from Sarasota through Lee counties with small patches also detected alongshore and offshore of northern Monroe County and offshore of the lower Florida Keys. Respiratory irritation and fish kills continue to be reported in the affected areas.
