2020 Seasonal Forecast of Harmful Algal Blooms (HAB) for Lake Erie

 

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. NOAA issues forecasts for Lake Erie after sampling confirms presence of the HAB species Microcystis, during bloom season (typically July to October) when conditions are optimal for growth. The Lake Erie HAB Forecast is updated daily and provides information on current extent and trajectory of HABs as they form.

 

This map models bloom position from date of satellite imagery to a minimum of 96 hours from date of publication, using water currents data from the Lake Erie Operational Forecast System (LE-OFS). Potential for bloom movement is forecast in 3-dimensions with a hydrodynamic model using satellite imagery and currents. The modeled output does not contain clouds. Gray coloring indicates the absence of chlorophyll.
