The effects of Hurricane Isaac in Louisiana were more severe than anywhere in the storm's path, and included $611.8615 million in damages and five total deaths.[nb 1] Forming from a tropical wave in the central Atlantic, Isaac traversed across many of the Lesser and Greater Antilles, before reaching peak intensity with winds of 80 mph (130 km/h) on August 28, 2012 while in the Gulf of Mexico.[nb 2] Nearing the coast of Louisiana, the Category 1 hurricane slowly moved towards the west, making two landfalls in the state with little change of intensity prior to moving inland for a final time. The hurricane weakened and later dissipated on September 1 while over Missouri. Before landfall, Governor Bobby Jindal declared a state of emergency to the state, as well as ordering the mandatory evacuation of 60,000 residents in low-lying areas of Louisiana along the Tangipahoa River in Tangipahoa Parish.
Isaac's large wind field contributed to a strong storm surge peaking at 11.03 ft (3.36 m) at a buoy offshore of Shell Beach. The strong waves inundated large areas of the state's coastal regions, particularly in Plaquemines Parish. The hurricane also brought heavy rainfall, leading to severe inland flooding. Rainfall amounts peaked statewide at 23.22 in (590 mm) in Hammond. Including adjacent states, the storm surge and inland flooding alone caused $407 million in insured losses. Isaac's strong winds caused infrastructural and crop damage, in addition to storm surge and heavy rains. A WeatherBug weather station in Poydras reported a 97 mph (156 km/h) wind gust, the fastest measured in association with the storm. The strong winds also caused a widespread power outage, with 901,000 electricity customers losing power. In the aftermath of the hurricane, the Federal Emergency Management Agency (FEMA) granted $204.8 million in public assistance funds and $129.3 million in individual assistance funding.
