The Florida Fish and Wildlife Conservation Commission (FWC) reports that the red tide organism, Karenia brevis, continues to be detected in Southwest Florida, with bloom concentrations observed in Sarasota and Charlotte counties. Fish kills and respiratory irritation suspected to be related to red tide have been reported in multiple counties.
Satellite imagery suggests that the bloom, which was previously concentrated in distinct offshore patches, has spread northward along the coast and decreased in intensity. A smaller patch of elevated chlorophyll was also observed near the border of Collier and Monroe counties.
