Red Tide Status (March 17, 2017)
A patchy bloom of the Florida red tide organism, Karenia brevis, persists in Southwest Florida from southern Pinellas to Lee counties.
Over the past week, Karenia brevis was observed at very low to low concentrations in two samples collected from Pinellas County; background to very low concentrations in three samples collected from Manatee County; background to medium concentrations in thirteen samples collected from Sarasota County; background to medium concentrations in four samples collected from Charlotte County; and background to low concentrations in eight samples collected from Lee County.
Additional samples collected throughout Florida over the past week did not contain K. brevis.
Forecasts for Southwest Florida by the USF-FWC Collaboration for Prediction of Red Tides predict net southern movement of surface waters and southern, onshore movement of subsurface waters from Pinellas to northern Monroe counties over the next three days.
For the week of March 20th, a single report will be issued on Thursday, March 23, 2017. We will return to biweekly reporting (Wednesday and Friday) the following week.

FWC's Red Tide Action Report
Red tide is a naturally-occurring microscopic alga that has been documented along Florida’s Gulf Coast since the 1840’s and occurs nearly every year. Blooms, or higher-than-normal concentrations, of the Florida red tide alga, Karenia brevis, frequently occur in the Gulf of Mexico. Red tide begins in the Gulf of Mexico 10 to 40 miles offshore and can be transported inshore by winds and currents.
