Saharan Dust Cloud Heads to U.S., Impacting Air Quality

A massive Saharan dust plume is on its way to the United States, following its passage across the Caribbean. This annual phenomenon, known as the Saharan Air Layer (SAL), occurs when strong winds lift dust from the Sahara Desert high into the atmosphere. The dust then travels thousands of miles westward across the Atlantic Ocean.

While the dust cloud can create spectacular sunsets and limit hurricane formation by suppressing atmospheric moisture, it also poses health risks. The fine dust particles can irritate the respiratory system, especially for individuals with asthma or other breathing difficulties. Air quality alerts may be issued in affected areas.

Experts recommend that people with respiratory conditions limit their time outdoors during the peak of the dust cloud's arrival. Monitoring local air quality reports is also advised. The dust cloud is expected to linger for several days before dissipating.
