HARMFUL ALGAL BLOOM FORECASTS

Texas Satellite Imagery

Composite 8-days of satellite imagery up to 09-08-2025
showing location of algae bloom which may include algae besides K. brevis.

Water samples from 09-01-2025 to 09-08-2025 found Karenia brevis was either not present or at background levels so there is no risk of respiratory irritation and blooms in imagery are unlikely to be a red tide (caused by Karenia brevis).
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.
