Red Tide Mid-Week Update for September 26, 2018
Current Conditions
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 continues in Northwest Florida. Additional details are provided below.
In Southwest Florida, K. brevis concentrations generally increased in Sarasota and Lee counties over the past week. Observations of >1,000,000 K. brevis cells per liter (“high” concentrations) occurred in Southwest Florida over the past week, in and/or offshore of Pinellas, Manatee, Sarasota, Charlotte, and Lee counties and >20 miles offshore of Collier County. In Northwest Florida, K. brevis concentrations generally decreased in Bay and Pasco counties and increased in Gulf County; “medium” concentrations were observed from eastern Bay through Gulf counties.
In Southwest Florida, reports of fish kills were received for multiple locations in and/or offshore of Pinellas, Manatee, Sarasota, Charlotte, Lee and Collier counties. In Northwest Florida, reports of fish kills were received for Walton, Bay and Gulf counties. Respiratory irritation was reported in Southwest Florida (in Pinellas, Manatee, Sarasota, Lee and Collier counties) and in Northwest Florida (in Gulf County).
Three-day forecasts by USF-FWC Collaboration for Prediction of Red Tides for Pinellas County predict variable currents with net southern movement of surface waters and southeastern transport of subsurface waters. Forecasts for Manatee to northern Monroe counties predict net southwestern movement of surface waters and southeastern transport of subsurface waters over the next three days. Forecasts for Northwest Florida predict net eastern transport of surface waters and northeastern movement of subsurface waters from Escambia to Gulf counties.
The next complete red tide status report will be posted on Friday, September 28th.

Red Tide Mid-week Update for September 12, 2018
Current Conditions
A bloom of the Florida red tide organism, Karenia brevis, persists in Southwest Florida and extends from northern Pinellas to Lee counties along ~125 miles of coastline. Aerial surveys conducted on 9/6 and 9/11 as well as recent water sampling indicate that the bloom of K. brevis still extends offshore (10 miles or more) in some areas. A bloom of K. brevis was also observed in Northwest Florida for the first time this past week.
Observations of >1,000,000 K. brevis cells per liter (“high” concentrations) occurred in samples collected in or offshore of Pinellas, Manatee, Sarasota, Charlotte, and Lee counties and relative to last week, multiple locations in Pinellas, Sarasota, Charlotte and Lee counties showed increased K. brevis concentrations. Decreased cell concentrations were observed in Collier County. In Northwest Florida, very low to low cell concentrations (<100,000 cells per liter) were reported from Okaloosa to Bay counties.
In Southwest Florida, reports of fish kills were received for multiple locations in and/or offshore of Pinellas, Manatee, Sarasota, and Lee counties. In Northwest Florida, reports of fish kills were received in and offshore of Panama City Beach (Bay County). Respiratory irritation was reported in Southwest Florida (in Pinellas, Manatee, Sarasota, and Lee counties).
Forecasts by the USF-FWC Collaboration for Prediction of Red Tides for Pinellas to northern Monroe counties predict net southern movement of surface waters for most areas and net southeastern transport of subsurface waters over the next three days. Forecasts for Northwest Florida predict net eastern transport of surface and subsurface waters.
The next complete red tide status report will be posted on Friday, September 14th.

Red Tide Status Update for September 7, 2018
Current Conditions
A bloom of the Florida red tide organism, Karenia brevis, persists in Southwest Florida and extends from Pinellas to northern Collier counties along ~120 miles of coastline. Observations of >1,000,000 K. brevis cells per liter (“high” concentrations) occurred in samples collected in or offshore of Sarasota, Charlotte, and Lee counties only. Relative to last week, multiple locations in Sarasota and Collier counties showed decreased cell concentrations. An aerial survey conducted on 9/6 as well as recent water sampling and chlorophyll satellite imagery indicate that the bloom of K. brevis likely extends offshore (10 miles or more) in some areas of the bloom region. Patchy accumulations of the marine cyanobacterium Trichodesmium were also observed ~10 miles offshore of Manatee and Sarasota counties. Persistent surface currents—prior to, during, and after the passage of Tropical Storm Gordon—likely played a role in transporting cells of K. brevis to the northwest. More specific details are provided below.
- In Southwest Florida over the past week, K. brevis was observed at background to medium concentrations in or offshore of Pinellas County, background to medium concentrations in Manatee County, background to high concentrations in Sarasota County, very low to high concentrations in or offshore of Charlotte County, background to high concentrations in or offshore of Lee County, and medium concentrations in Collier County. For additional information, view the southwest coast report and map .
- In Northwest Florida over the past week, K. brevis was observed at very low concentrations in one sample collected from Bay County. For additional information, view the Northwest Coast report and map .
- Samples collected along the east coast of Florida over the past week did not contain K. brevis. For additional information, view the East Coast report and map .
Fish Kills
Over the past week, reports were received for multiple locations in Pinellas, Manatee, Sarasota, and Lee counties. More detailed information is available at /fishkill.
Respiratory Irritation
Respiratory irritation was reported over the past week in Manatee, Sarasota, and Lee counties. For additional information, view the Southwest Coast report .
Forecast
Forecasts by the USF-FWC Collaboration for Prediction of Red Tides for Pinellas to northern Monroe counties predict net northwestern movement of surface waters for most areas and net southeastern transport of subsurface waters over the next three days. A change from northwestern to southeastern surface transport is predicted to occur towards the end of this period.
