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.

Bulletin Distribution:
Operational HAB-OFS bulletins for Southwest Florida and Texas are produced twice weekly during active HAB events and once weekly during inactive bloom status. Operational HAB-OFS bulletins for Northwest Florida and East Florida are produced twice weekly upon confirmation of an active HAB event until confirmed termination of the bloom. Distribution is restricted to individuals with natural resource management responsibility to respond to a HAB event and HAB research affiliates.

Due to distribution restrictions, HAB bulletins are posted to this archive with a one to two week delay.

Bulletin Content:
HAB-OFS bulletins provide information on potential or confirmed harmful bloom events, chlorophyll levels, and forecasted wind conditions. The bulletins also provide forecasts for potential human impacts associated with confirmed harmful blooms, spatial bloom extents, movement, intensification and the potential for bloom formation. (Daily impact forecasts by county are also available to the public on the main HAB-OFS page).
