Harmful Algal Bloom Forecasts
Harmful algal blooms (HABs) are a rapid growth of algae that produce toxic or harmful effects on people, fish, marine mammals, birds and local economies. NOAA HAB forecasts aid those who respond to bloom impacts and help members of the public make informed decisions if a bloom is affecting their area.
Gulf of Mexico HAB Forecast
NOAA issues weekly forecasts for the eastern and western Gulf of Mexico when conditions become favorable for HABs of the red tide species, Karenia brevis (typically in August). Twice-weekly forecasts are released during an active bloom with additional updates when conditions change.
Blooms of harmful algae, like this "red tide" off the coast of Texas, can cause illness and death in humans and animals.
