Red Tide Status Update for November 16, 2018

Current Conditions
Bloom concentrations of the red tide organism, Karenia brevis, persist on Florida’s Southwest and Northwest coasts. Patchiness was observed in both areas. On the East Coast, bloom concentrations of K. brevis are no longer present. Additional details are provided below.

In Southwest Florida, observations of >1,000,000 K. brevis cells per liter (“high” concentrations) occurred in and/or offshore of Pinellas, Sarasota, Charlotte, and Lee counties. “Medium” concentrations were observed in these same counties, and also in Manatee County and offshore of Monroe County. Relative to last week, K. brevis concentrations increased in parts of Pinellas, Manatee, Charlotte, and Lee counties. In Northwest Florida, “high” concentrations of K. brevis were observed in Bay County and “medium” concentrations were observed there as well as in Santa Rosa County.

Fish Kills
In Southwest Florida, fish kill reports were received for multiple locations in Pinellas, Manatee, and Sarasota counties, and in and offshore of Charlotte County. In Northwest Florida, fish kills were reported in Okaloosa and Bay counties. On the East Coast of Florida, a fish kill was reported in Palm Beach County. More detailed information is available at http://myfwc.com/fishkill.

Respiratory Irritation
Respiratory irritation was reported over the past week in Southwest Florida (in Pinellas, Manatee, Sarasota and Lee counties), Northwest Florida (in Okaloosa County), and on the East Coast (Palm Beach County). For additional information, view the southwest coast report Adobe PDF, the northwest coast report Adobe PDF, and the east coast report Adobe PDF.

Forecast
Forecasts by the USF-FWC Collaboration for Prediction of Red TidesExternal Website for Pinellas to northern Monroe counties predict net southwestern movement of surface waters and southeastern movement of subsurface waters in most areas over the next four days. Four-day forecasts for Escambia to western Gulf counties predict net southeastern movement of surface waters and net eastern transport of subsurface waters.

Due to the holiday next week, a complete status report will be issued on Wednesday, November 21st, rather than on Friday. Please check our daily sampling map which can be accessed from the top of this page.
