The Saharan Air Layer (SAL)
The Saharan Air Layer (SAL) is a vast, hot, dry, and often dust-laden atmospheric layer
that forms over the Sahara Desert in northern Africa. This is a regular phenomenon that
occurs between March to September each year. It travels westward across the Atlantic
Ocean, reaching the Caribbean, Gulf of Mexico, and even parts of the southeastern United
States.
Health Advisory: Protecting Yourself During the Saharan Dust Plume
The Ministry of Health advises residents of Saint Kitts and Nevis to take precautions as a
significant Saharan dust plume moves through the Federation en route to the U.S. Gulf
Coast. Such increased levels of airborne particulates and dust can significantly affect
individuals with pre-existing respiratory conditions, such as asthma and chronic
obstructive pulmonary disease (COPD), as well as those with allergies.
Exposure to these pollutants may lead to symptoms including:
• Itchy or burning eyes
• Runny nose and sneezing
• Chest tightness and wheezing (particularly in asthmatic individuals)
In severe cases, these symptoms can escalate to difficulty breathing, requiring immediate
medical attention.
Recommendations for At-Risk Individuals:
• Limit Outdoor Activities: Stay indoors as much as possible during dust events.
• Wear Protective Masks: Use a facemask to reduce inhalation of harmful particles
when going outdoors.
• Practice Respiratory Hygiene: Cover coughs and sneezes with a disposable tissue
or your elbow, avoid touching your face, and wash hands regularly with soap and
water or use an alcohol-based hand sanitizer.
• Monitor Symptoms: Individuals with respiratory conditions should ensure they
have access to their prescribed medications, such as rescue inhalers, and seek
medical care if symptoms worsen.
• Seek Medical Attention if Necessary: If you experience severe symptoms or your
condition worsens, consult a healthcare professional promptly
By taking these precautions, individuals can better protect themselves from the adverse
health effects associated with increased airborne particulates and dust. Please remain safe
as the Saharan dust plume makes its way across our Federation.
