Red Tide Current Status

This summary report of current red tide conditions around Florida includes a map of sampling results and regional status reports.

Red Tide Status (October 17, 2014)

Karenia brevis, the Florida red tide organism, was not detected this week in or alongshore of Escambia, Gulf, Wakulla, Taylor, Dixie, Levy, and Pasco counties.  One sample collected inshore of Bay County contained background concentrations of K. brevis and another collected alongshore of Franklin County contained very low concentrations. In addition, one sample collected alongshore of Pinellas County contained background concentrations of K. brevis and one sample collected alongshore of Charlotte County contained very low concentrations.

Other samples collected throughout Florida this week did not contain K. brevis.

Satellite images from the Optical Oceanography Laboratory at the University of South Florida show patches of high algae concentrations offshore of Franklin, Wakulla, Taylor, Dixie, Levy, and Citrus counties.

Forecasts by the USF-FWC Collaboration for Prediction of Red Tides (CPR), a partnership between the University of South Florida’s College of Marine Science and the Florida Fish & Wildlife Conservation Commission, project S movement of surface waters and S/SE movement of bottom waters in the northeast Gulf of Mexico over the next 3 days.  Based on these forecasts and observed red tide concentrations, the map below shows the potential for red tide effects within 5 km of shore. Inshore red tide effects may include fish kills and respiratory irritation.
