Monster Saharan dust cloud arrives in Mexico

The 3,500-mile-long cloud, dubbed the "Godzilla dust cloud," traveled thousands of miles from North Africa before reaching the Caribbean and now Mexico.

This year, the dust is the most dense it has been in over half a century according to meteorologists.

The Saharan dust plume will hang over Mexico and the southeastern United States until the middle of next week, deteriorating the air quality in places where the number of COVID-19 cases has recently spiked.

Air pollution can be especially detrimental for people who are at risk for or suffer from cardiovascular and respiratory illnesses according to health authorities. Heart and lung problems heighten the risk of severe COVID-19.
