Envirosite Provides Environmental Data
to Aid in Hurricane Zeta Cleanup Efforts.
Hurricane Zeta made landfall on October 28, 2020 at 4 pm CDT near Cocodrie, Louisiana, as a Category 2 hurricane with winds raging at 110 mph, only one mph shy of a Category 3 hurricane. In addition to high winds, the storm produced over 4 inches of rain in some areas of Louisiana, Mississippi, Alabama, and Florida. This was the fourth hurricane to hit Louisiana this year. The storm has left millions of homes and businesses without power in the affected areas. We combined the National Hurricane Center's Storm Surge data with Envirosite's extensive environmental and geospatial data sets to help aid public officials and environmental professionals.
Envirosite's Storm Surge impact analysis indicates the highest number of contaminated sites at risk of flooding in these four states:
- Louisiana: Lafourche, Terrebonne, and Plaquemines Counties
- Mississippi: Harrison and Jackson Counties.
- Alabama: Mobile County.
- Florida: Escambia and Santa Rosa Counties.
