Respiratory and Eye Irritation:

Temporary coughing, sneezing, itchy throat and eyes. Symptoms may be more severe for those with pre-existing respiratory conditions such as asthma.

What Can You Do:

  • Be aware that bloom impacts may be temporary and not all coastal areas will be affected throughout the region.
  • If you experience uncomfortable symptoms consider leaving the surrounding area in favor of nearby beaches that are not impacted.
  • If you can, plan your trip by checking beach conditions before you go:
    • NOAA's Conditions Reports include Respiratory Irritation Forecasts.
    • Hotels and tourism centers will often have information about which beaches are experiencing impacts and alternate beach options.
      If necessary, consult your healthcare provider or call the Poison Information Center (1-800-222-1222) for 24 hour assistance from a medical professional.
