Bloom concentrations of the Florida red tide organism, Karenia brevis, persist on Florida’s Southwest, Northwest and East coasts. Patchiness was observed in each region.

In Northwest Florida, K. brevis was observed in or offshore of Escambia, Santa Rosa and Okaloosa counties, with “medium” concentrations occurring in Okaloosa and Santa Rosa counties.

On the East Coast, observations of K. brevis spanned Brevard to Miami-Dade counties. “High” concentrations were observed at one site in Indian River County and “medium” concentrations occurred in Indian River and Broward counties.

In Southwest Florida, reports of fish kills were received for Pinellas and Sarasota counties.

In Northwest Florida, reports of fish kills were received for Okaloosa and Pasco counties.

Along the East Coast of Florida, reports of fish kills were received for Brevard, Indian River, Palm Beach and Broward counties.
