Hurricane Helene flooding poses multiple health risks. Here's what to know.

Hurricane Helene's wake of massive rains and flooding isn't just destructive to property — it is also a major health and safety risk, leaving residents in the storm's path stranded and potentially exposed to waterborne illnesses and other dangers. 

As authorities rush to airdrop supplies, restore power and clear roads, the number of storm-related deaths climbed past 100 across the Southeast.

In the devastated city of Asheville, North Carolina, Megan Drye, who was rescued, watched as her 7-year-old son Micah and her parents got swept away into the flood. They were stranded on a roof when it collapsed into the water.
