Harmful Algal Bloom Forecasts

Harmful algal blooms (HABs), the rapid growth of algae, can produce toxins that have harmful effects on people, fish, marine mammals, and birds.

NOAA’s Center for Operational Oceanographic Products and Services (CO-OPS) provides routine HAB forecasts to help members of the public make informed decisions when a bloom is temporarily affecting their area. The forecasts also aid people responsible for responding to bloom impacts.
