HARMFUL ALGAL BLOOM FORECASTS

Southwest Florida Satellite Imagery

Composite 8-days of satellite imagery up to 08-18-2026 showing location of algae bloom which may include algae besides K. brevis. Overlaid cell count data provided by several contributors. The past few days of imagery can be seen at the HAB monitoring site.

Water samples from 08-11-2026 to 08-18-2026 detected red tide (caused by Karenia brevis) along the coast at levels that pose a respiratory irritation risk in DUVAL and ST. JOHNS counties.
The images were derived from Copernicus Sentinel-3 satellite data from the European Organisation for the Exploitation of Meteorological Satellites (EUMETSAT) and were processed by NOAA, National Centers for Coastal Ocean Science. Cell count data were provided by several contributors.
