Major Hurricane Laura tracked north northwest across the Central and Northern Gulf of Mexico from the Central Carribean Sea near Cuba, making landfall in Southwest Louisiana near Cameron around 1 am on August 27th as a strong Category 4 hurricane with maximum sustained winds near 150 mph, and a minimum central pressure of 938 mb. Laura remained a hurricane as it tracked north across Southwest and Central Louisiana and into Natchitoches Parish, before weakening to a tropical storm as it moved northeast across North-central Louisiana and South-central Arkansas. A combination of observed and estimated wind gusts ranged from 50-90+ mph, resulting in numerous to widespread downed trees and power lines over these areas throughout the morning and early afternoon, before winds weakened by mid-afternoon with the departure of Laura into Southern Arkansas. Widespread rainfall amounts of 2-6 inches was observed across North Louisiana, with higher amounts of 6-8+ inches recorded across Southern and Western DeSoto, Sabine, Natchitoches, Western Grant, Winn, Jackson, and Eastern Bienville Parishes. Flooding was mostly confined to Natchitoches and Western Caddo Parishes.

Grant Parish alone was 4th in the state with the amount of timber lost, with over $111 million. Entergy reported that Hurricane Laura caused $1.7 billion to its infrastructure throughout Louisiana.
