The red tide organism, Karenia brevis, was observed at background concentrations in Southwest Florida and Northwest Florida over this past week. Additional details are provided below.

Over the past week in Southwest Florida, K. brevis was observed at background concentrations in one sample collected from Collier County.

In Northwest Florida over the past week, K. brevis was observed at background concentrations in one sample collected from Okaloosa County.

Along the Florida East Coast over the past week, K. brevis was not observed.

In Southwest Florida over the past week, fish kill reports were received for Collier County (see https://myfwc.com/research/saltwater/health/fish-kills-hotline).

Respiratory irritation was reported over the past week in Southwest Florida in Lee County.

Forecasts by the USF-FWC Collaboration for Prediction of Red Tides for Pinellas to northern Monroe counties predict net northwestern transport of surface waters and net southeastern movement of subsurface waters in most areas over the next four days.

The next status report will be issued on Friday, March 1. Please check our daily sampling map, which can be accessed via the online status report on our Red Tide Current Status page.

This information, including maps and reports with additional details, is also available on the FWRI Red Tide website. The website also provides links to additional information related to the topic of Florida red tide including satellite imagery, experimental red tide forecasts, shellfish harvesting areas, the FWC Fish Kill Hotline, the Florida Poison Information Center (to report human health effects related to exposure to red tide), and other wildlife related hotlines.
