Hurricane Milton could change Florida's coastline forever
The coastline of Florida's west coast is undergoing significant changes, primarily due to the effects of hurricanes like Milton and Helene. Coastal erosion, overwash, and inundation are key concerns, as these storms intensify the natural processes that reshape the shoreline. For example, 95% of the sandy beaches along Florida's west coast are expected to be continuously submerged by ocean water, according to the USGS. This process, called inundation, leads to severe erosion and damage to coastal ecosystems.
Overwash occurs when storm surges push water and sand beyond the dunes, altering the beach's profile and reducing the protective barrier these dunes provide against future storms. This not only changes the coastline but also leaves nearby communities more vulnerable. In addition, sand is often pushed inland, blocking roads and further reshaping the landscape. The repeated impacts from hurricanes like Helene have exacerbated these processes, making the coastline even more fragile as new storms, like Milton, approach.
