St. Charles Parish President Matthew Jewell ordered a mandatory evacuation Sunday ahead of Sally's expected impacts to southeast Louisiana.
A post on the parish's Facebook page warned "a high probability the storm will cause widespread power outages and inhibit the availability of crucial and emergency services."
“This is a storm everyone needs to take seriously. We are likely to see tropical storm force and hurricane strength winds for longer than Hurricane Katrina, a storm surge of 4-7 feet and the possibility of 20 inches of rain. We want residents to heed our warnings and make preparations to leave now,” said President Jewell.
