About the Operational HAB Bulletin

Southwest Florida HAB Bulletin Image

Harmful algal blooms of Karenia brevis, the organism responsible for red tide in the Gulf of Mexico, can impact the health of humans and animal life. The blooms are patchy in nature and the impacts vary by location and throughout the day depending on nearby bloom concentrations, ocean currents, surf conditions, and wind speed and direction. The NOAA HAB Bulletins contain an analysis of ocean color satellite imagery, field observations, models, public health reports and buoy data and forecasts of potential K. brevis bloom transport, intensification and associated respiratory irritation based on the analysis of information from HAB-OFS Contributors & Data Providers. Daily respiratory irritation forecasts by region are also available to the public on the Conditions Report page.

Harmful algal bloom bulletins are issued for the Gulf of Mexico by the National Oceanic and Atmospheric Administration (NOAA) National Ocean Service and the National Environmental Satellite Data and Information Service in order to provide notification of bloom conditions to state and local coastal managers in the Gulf of Mexico. Due to distribution restrictions, HAB bulletins are posted to this archive with a one to two week delay.
