Red Tide Current Status

Current Conditions

Over the past week, the red tide organism, Karenia brevis, was observed in 14 samples collected from Northwest Florida. Bloom concentrations (>100,000 cells/liter) were not observed. We continue to use satellite imagery (USF and NOAA NCCOS) to help track nearshore and offshore conditions. Imagery from November 13 revealed slightly elevated chlorophyll levels in Northwest Florida in Bay County, Gulf County (St. Joseph Bay), and Franklin County (see Northwest Coast map below). 

Additional details are provided below.

• In Southwest Florida over the past week, K. brevis was not observed. For additional information, view the Southwest Coast report and map.
• In Northwest Florida over the past week, K. brevis was observed at background to low concentrations in Bay County, very low concentrations in Gulf County, and background and very low concentrations in Franklin County. For additional information, view the Northwest Coast report and map.
• Along the Florida East Coast over the past week, K. brevis was not observed. For additional information, view the East Coast report and map.

Fish Kills

Fish kills suspected to be related to red tide were reported to FWC's Fish Kill Hotline or other partners over the past week in Northwest Florida (Bay and Gulf counties).

Respiratory Irritation

Respiratory irritation suspected to be related to red tide was not reported over the past week in Florida. For forecasts that use FWC and partner data, please visit the National Oceanic and Atmospheric Administration’s Gulf Coast Harmful Algal Bloom Forecast.

Forecast

Short-term (3.5-day) forecasts by the USF-FWC Collaboration for Prediction of Red Tides predict variable transport of surface waters along the Gulf Coast. Subsurface currents are variable from Bay County to Pasco County, and southeastern from Pinellas County to northern Monroe County in most areas.
