Red tide continues to be detected in Southwest Florida, with varying concentrations reported in different counties. While bloom levels were not observed in samples collected over the past week, a large offshore patch of elevated chlorophyll, potentially containing red tide, persists from Pasco to Collier counties.
Key takeaways:
- Offshore presence: Satellite imagery indicates a significant patch of chlorophyll offshore, which may contain red tide. Confirmatory sampling will be conducted when weather permits.
- Nearshore impacts: Red tide was detected at low to very low concentrations in many Southwest Florida counties. Fish kills and respiratory irritation were reported in some areas, particularly along the coast and offshore of Collier County.
- East Coast clear: No red tide was observed along Florida’s East Coast.
- Mixed algal species: Nearshore samples show a mix of algal species, including diatoms, which may be contributing to the chlorophyll signal seen in satellite imagery.
Current Status:
- Southwest Florida: Red tide concentrations ranged from background to low levels in most counties, with some higher concentrations in Manatee County.
- Northwest Florida: Background to very low concentrations were observed in Franklin County.
Forecast:
- Models predict a net northwestern movement of surface waters and southeastern transport of subsurface waters in most areas over the next few days.
