And with high chances of rain on those days, sulfuric acid droplets would fall, creating another menace known as acid rain, CNN meteorologist Michael Guy says. The amount of acid rain depends on the concentration of sulfur dioxide in the air, CNN's Guy says. Determining how acid rain affects human health is complicated, and Guy says the effects on the skin are unclear. "Walking in acid rain, or even swimming in a lake affected by acid rain, is no more dangerous to humans than walking in normal rain or swimming in non-acidic lakes," the EPA says. But acid rain can contaminate household water supplies by leaching metals from building and plumbing materials, the USGS says.
