Aid in Hurricane Delta Cleanup Efforts.
Hurricane Delta made landfall on October 9th at 6 pm CDT near Creole, Louisiana as a Category 2 hurricane with winds raging at 100 mph. This is the same area where Hurricane Laura passed in September leaving piles of wreckage and blue tarped rooftops. Hurricane Delta is the 10th storm to hit the United States this year. The National Hurricane Center published Hurricane Delta storm surge maps for the affected states. Envirosite combined the National Hurricane Center's Storm Surge data with our comprehensive 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 Louisiana are in Calcasieu, Terrebonne, Lafourche, Vermilion, St. Charles Counties. For Mississippi, the highest number of contaminated sites at risk are in Hancock and Harrison Counties. For Texas, the highest number of contaminated sites at risk are in Jefferson and Orange Counties.
