The bloom of Karenia brevis (commonly known as red tide) is no longer detected along the coast of southwest Florida. No respiratory irritation associated with K. brevis is expected in this region. **Note: As of today, March 7, twice weekly Florida bulletins will no longer be issued. The region will continue to be monitored and twice weekly bulletins will resume as conditions warrant.**
What do the respiratory irritation forecast levels mean? Red tide does not affect everyone equally. For each of the levels that NOAA forecasts, this table shows who might experience symptoms.
