Respiratory Irritation Alerts Issued

15 Nov 2022

The current HABscope forecast calls for moderate to low respiratory irritation due to red tide at Tarpon Bay Road Beach on Sanibel today and tomorrow, with a high chance at the Boca Grande pier. Using current wind predictions from the National Weather Service that are combined with Karenia brevis cell counts gathered by volunteers along Florida’s west coast, the forecast provides information on when the red tide caused by K. brevis could be impacting area beaches so that people who are susceptible to its impacts will know the risks.

 

 

 

Impacts happen when K. brevis, the organism that causes red tides in the Gulf of Mexico, is present and winds blow onshore or alongshore (generally from the west). Offshore winds (typically from the east) usually keep respiratory impacts to a minimum.

 

 

 

Human Health Risks

 

Most People: Experience minor respiratory irritation — coughing, sneezing, teary eyes

 

and an itchy throat — when red tide is present and winds are blowing onshore. These

 

symptoms go away when you leave the beach.

 

 

 

People with Chronic Lung Problems: People with asthma, COPD or other lung

 

diseases can have severe reactions when they breathe in airborne red tide toxins.

 

Health officials advise that these people avoid red tide areas altogether and take all

 

medications as prescribed, including having access to rescue inhalers. People with

 

chronic lung disease should leave the beach if they begin experiencing respiratory

 

problems, even if red tide is at very low or low concentrations.
