In Southwest Florida over the past week, K. brevis was observed at background concentrations in Pinellas County, background to medium concentrations in Sarasota County, very low to medium concentrations in and/or offshore of Charlotte, Lee and Collier counties and low concentrations offshore of Monroe County. Bloom concentrations (>100,000 K. brevis cells per liter) persist in Sarasota, Charlotte, Lee and Collier counties. These include an estuarine site in Sarasota County, estuarine sites in Charlotte County and coastal, estuarine and offshore sites in Lee and Collier counties. High concentrations (>1 million cells per liter) were observed in 12 samples from Charlotte, Lee and Collier counties.
