Multiple states have issued a hazardous air warning after a slew of dust storms are set to sweep the U.S.
More specifically, as reported by the Daily Mail, the US Environmental Protection Agency has declared the air in Watertown, South Dakota, to be "hazardous" to human health. This comes after around 300,000 people have been engulfed in this "hazardous" air.
The World Air Quality Index project said that the air quality in Watertown hit a record 439. A level of 300-500 means that everyone should avoid outside physical activity, according to the EPA.
But Watertown isn't the only major city to receive a warning. Fargo, North Dakota, which sits on the border with Minnesota, also faced a plume of "unhealthy air."
Experts have warned that these dust storms will lower the air quality in all areas affected. But the areas with the most dense populations have been the ones hit the hardest with the warnings.
These air quality alerts have come alongside a Red Flag Warning for seven states, including Colorado, Iowa, Nebraska, and Wisconsin. This warning means that major fires may occur in a short amount of time due to environmental conditions. These conditions include low humidity as well as strong winds.

How Dangerous Is Inhaling Dust Storm Particles?
Well, the short answer is pretty darn dangerous.
The main pollutant within the dust storms ravaging the Midwest at the moment is called PM10. This is a fine particulate matter that consists of small particles. They're really small, 10 micrometers in diameter—even thinner than a human hair.
They can cause issues with the eyes, nose, and throat, according to the CDC. They also add that people suffering from lung conditions such as COPD are more likely to struggle with the effects of PM10 particles.
Health officials warned in a statement, "Particle pollution can get deep into the lungs and cause serious health problems such as asthma attacks, heart and lung disease symptoms, and increased risk of lung infections."
They also added that people should keep their windows and doors closed and use air purifiers where possible to make sure they are safe.
