Texas Harmful Algal Bloom Bulletin

Please find up-to-date analysis, satellite imagery, and forecasts at the Texas HAB Forecast System.


This is a reminder to check the Texas HAB Forecast System, linked above, for up-to-date conditions.

Texas Parks and Wildlife Department observed up to low concentrations of Karenia brevis over the past week, particularly in the Galveston, TX area. Very low concentrations, but above background level, have also been reported in the Port O’Connor area. Satellite imagery from 20 September shows elevated fluorescence, likely due to K. brevis well offshore of the Crystal Beach, TX area. 

Red tide (K. brevis) blooms are inherently patchy and can move quickly with tides and currents. While this elevated fluorescence does not pose any immediate risk to the beaches or near-shore coastal areas, we will continue to use satellite imagery to monitor conditions.

This bulletin provides forecast updates and reminders of the Karenia brevis harmful algal blooms (HABs) for coastal Texas. Please find up-to-date analysis, satellite imagery, and forecasts at the Texas HAB Forecast System.

Subscribers will receive notices of changes or improvements to the forecasting system. Subscribers will also be periodically reminded to check the HAB Forecast System, especially when there are major changes in bloom status.
