List of Louisiana hurricanes (2000–present)
From Wikipedia, the free encyclopedia
From 2000 to the present, at least 28 tropical or subtropical cyclones affected the U.S. state of Louisiana. According to David Roth of the Hydrometeorological Prediction Center (HPC), a tropical cyclone makes landfall along the coastline about two times every three years, and a hurricane makes landfall once every 2.8 years.[1]
The most active month for tropical cyclone activity in the state is September, with ten total storms, while no recorded storms have affected Louisiana during the months of December through May. The most intense storm to affect the state in terms of barometric pressure is Hurricane Katrina of 2005, which also caused the most fatalities and damage with 1,833 total deaths and over $100 billion in total damages.[nb 1] Katrina is also tied with Hurricane Harvey of 2017 as the costliest hurricane in the Atlantic basin. The 2020 hurricane season has seen the most landfalling tropical cyclones in a single season with 5 total storms. In terms of wind speed, Hurricane Ida, Hurricane Laura, and the 1856 Last Island hurricane are the strongest storms to affect the state, each producing maximum sustained winds of 150 mph (240 km/h), equivalent to Category 4 on the Saffir–Simpson hurricane scale.
