A red tide bloom has been reported, with water samples showing a moderate concentration of algae. This naturally occurring buildup of microscopic algae can harm fish and release toxins into the air, causing respiratory symptoms in people nearby. Symptoms can include burning eyes, coughing, and shortness of breath, and may be more severe for those with asthma or other breathing conditions.

The Texas Parks and Wildlife Department has collected water samples and reported fish kills and respiratory symptoms from September 7-11. Further details about the red tide bloom are available from the Texas Parks and Wildlife Department.
