Red Tide Prediction and Tracking for the Tampa Bay Region
The "X" represents the starting point where each sample was collected. The lines show the 3.5 day trajectory for each sample. The color represents the red tide concentration for each sample. Black lines represent simulated drifter trajectories.
This red tide short-term tracking product is a collaboration between the College of Marine Science, University of South Florida (CMS-USF) and the Florida Wildlife Research Institute (FWRI). Observations of Karenia brevis red tide cell concentration are put into the Tampa Bay Circulation Nowcast/Forecast Model (TBCOM), resulting in 1 day hindcast and 3.5 days forecast of the red tide trajectories. The "X" represents the starting point where each sample was collected. The lines show the 3.5 day trajectory for each sample. The color represents the red tide concentration for each sample. Black lines are not indicative of red tide; instead, they show where the current would take a simulated buoyant particle. These may be useful for search and rescue, or for tracking hazardous spills. The short-term red tide trajectory forecast products (uppper and lower water columns) are updated daily in the early morning.
Similar short-term forecast products for the entire West Florida Shelf coast can be seen from this webpage. Seasonal prediction of major red tide blooms is also made based on the satellite altimetry analysis.

The Tampa Bay Circulation Nowcast/Forecast Model (TBCOM) project is funded by the Pinellas County RESTORE Act Program to the College of Marine Science (CMS) at University of South Florida (USF). The HAB tracking tool has benefited from several sources of funding beginning with the FWC and USF. Additional resources from ONR, NOAA and NASA have helped advance the modeling effort
over the years.
