Red Tide Current Status

FWC reports on the current status of Karenia brevis blooms using tables, static maps, and interactive Google Earth maps. Archived status maps can be found in our Flickr gallery.

 

Red Tide Status (February 5, 2016)

A bloom of Karenia brevis, the Florida red tide organism, persists along Pinellas, Manatee, Sarasota, Charlotte, Lee, and northern Collier counties in Southwest Florida. Karenia brevis was detected in background to medium concentrations in 5 samples collected in and alongshore of Pinellas County; background to high concentrations in 74 samples collected in, along, and offshore of Manatee, Sarasota, Charlotte, and Lee counties; and very low to medium concentrations in 2 samples collected alongshore of northern Collier County. No samples were collected from Hillsborough County this week.

Additional samples collected throughout Florida over the past week did not contain K. brevis.

Respiratory irritation continues to be reported in several bloom areas of Southwest Florida including Siesta Key Beach, Longboat Key, and Englewood Beach. Fish kills have also been reported along Longboat Key and Englewood Beach. Forecasts by the USF-FWC Collaboration for Prediction of Red Tides show southern/alongshore movement of bloom waters in Southwest Florida over the next 3 days.
