Monitoring Hurricanes and Predicting Flooding in the Age of Climate Change
Still recovering from Hurricane Helene, which caused extreme precipitation, flooding, landslides, and other environmental disasters associated with severe weather, the southeastern part of the U.S. is predicted to be hit by another storm, Hurricane Milton. 
 
With Hurricane Helene having made landfall only a little over a week ago on September 27 th , many communities are still recovering. ABC reports that over 230 people have been killed as a result of flooding and destruction caused by Helene, with many still missing. 
 
Residents in these heavily impacted states, such as Florida, Georgia, South Carolina, North Carolina, Virginia and Tennessee, are still searching through the rubble of homes, urban centers, and hospitals for loved ones and belongings.

Among the dozens of publicly protected national parks, hundreds of wilderness areas, and thousands of state parks in the contiguous U.S., none are larger than the Adirondack Park, a 6 million-acre wilderness area that spreads across upstate New York. 
 
 With 3,000 lakes and ponds and 30,000 miles of rivers and streams, the waterways of the Adirondacks are enormous. Diverse aquatic habitats and ecosystems abound, along with bountiful recreational opportunities. 
 
 Nearly half of this land is owned by the state of New York and managed through the New York State Department of Environmental Conservation (DEC) as a forest preserve to return the wilderness to its “presettlement” state.
