Hurricane Laura made landfall along the Louisiana coast near Lake Charles in the early morning hours of August 27. It moved north into Central Louisiana during the morning and afternoon before turning to the northeast and tracking through Arkansas. Impacts from Laura were felt far from the center of the storm, which was mainly in the form of tropical storm force winds across portions of northeast Louisiana and southeast Arkansas. Farther east, into Mississippi, the tight pressure gradient that resulted from Laura was the cause for gusty winds across portions of western Mississippi. Winds were sustained 30 to 35 mph, gusting to 45 to 49 mph across portions of northeast Louisiana, southeast Arkansas and the northwest portion of Mississippi. This resulted in downed trees and power lines across the region. Since Laura moved inland fairly quickly, rainfall totals were not high. Rainfall amounts up to four inches occurred along and west of the Mississippi River and this resulted in some minor flooding.
