The demonstration page below provides Lake Erie HAB forecast information using the upgraded Lake Erie 3D model. This model improves on the current operational forecast by including vertical mixing of Microcystis algae. For that reason, nowcast and forecast information on this page may be different than on the current Lake Erie PDF forecasts. For questions and comments, please contact the HAB team at HAB@noaa.gov.
This map models bloom position from date of satellite imagery out to 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 HAB Tracker, a hydrodynamic model using satellite imagery and currents to project bloom transportation.
Each point represents a location used by the HAB Tracker
Forecast position of bloom using LEOFS modelled currents to move the bloom from the image. Surface scum is mixed through the water column by wind action across the lake surface. Each point represents a location used by HAB Tracker's model. Click a point to visualize bloom depth in the water column by date and modeled concentration.
