Louisiana was once a French-owned territory. Along with an approximate total of 828,000 square miles, it was sold to the United States for a mere $15 million dollars in 1803. Exactly nine years later, on April 30, 1812, Louisiana became a state.
Louisiana was named “La Louisanne” in honor of the King of France, King Louis XIV. To this day, there’s a heavy French influence that characterizes the state. The state is divided into 64 parishes (aka counties) and is the only US state that operates under the Napoleonic Code (French Emperor’s Civil Code).
In Louisiana you’ll discover a melting pot of cultures including Cajuns, French, French-Canadian, African, and modern American. This melting pot has subsequently resulted in the creation of multiple French dialects which are uniquely spoken there.
Louisiana is nicknamed the Pelican State, but is more popularly known as the birthplace of jazz and is the jazz capital of the world. It’s also the home state of Louis Armstrong.
Another thing Louisiana is recognized for is its food. Creole and Cajun food are not just a meal but a way of life, especially when you add a splash of hot sauce.
You haven’t truly gotten the taste of Louisiana if you haven’t tried their gumbo, andouille sausage, jambalaya, crawfish, oysters, beignets, meat pies, and possibly ventured out to try nutria, snake, and alligator. (Fun fact: the state has one of the largest alligator populations with 2 million living in the wild and approximately 300,000 living in farms.)
Louisiana boasts some of the prettiest views ever— that is, under good conditions. Unfortunately, it’s one of the hardest-hit states when it comes to natural disasters and the remnants of these disasters are oftentimes long-lasting. This article will shed light on previous disasters in the state, why they occur, and how to become prepared.
What natural disasters does Louisiana have?
Louisiana’s most common natural disasters include floods, hurricanes, severe storms, tornadoes, power outages, ice storms, and landslides.
Between 1953 and 2019, Louisiana declared 84 major disasters, of which floods and hurricanes happened the most according to FEMA.
Louisiana has a very high risk of flooding and unfortunately, the situation is expected to get much worse over time. An estimated 47% of properties are located in a flood risk area— that is almost every other home! Some sources suggest that over the next 30 years, the state will see a 62.8% increase in properties being at risk of flooding, especially if the sea level continues to rise.
The risk of flooding increases after periods of heavy rain, long-lasting precipitation, and hurricanes. New Orleans is sinking at a rate of 2 inches per year, therefore elevating its flood risk even more. Almost 1 million people in the Pelican State are currently at risk of coastal flooding.
One of the worst floods in recent history occurred in August 2019 in which was referred to as a 500-year event. Some areas received 20 to 30 inches of rain, thereby resulting in flash floods, rivers swelling, overflowing creeks and waterways. There was widespread destruction, including approximately 50,000 to 75,000 inundated structures, a significant loss in crops, livestock, and the fishing industry, and the death of 13 people. Many places located near the rivers remained flooded for up to 9 months. The cost of damages was estimated to be around $20 billion.
Another major flood event hit the state in 2021, particularly Lake Charles. Within 12 hours, over a foot of rain fell over the city, completely flooding downtown and nearby areas. A state of emergency was declared by the governor. The saddest part is that this event occurred less than a year after two devastating hurricanes swept through the region.
Preparing for floods is vital if you live in Louisiana. The most important place to start is to learn what your home and community’s risk is. Check out local flood maps for up-to-date information as erosion and other natural events can quickly alter your risk.
If you live in a flood zone, consider moving to a safer place. In the meantime, learn how to stay safe during such an event. If floodwaters get near, get to higher ground immediately and do not attempt to cross them.
Louisiana is a major target for hurricanes because it is located in the prime location along the Gulf of Mexico. While hurricane season begins June 1 and lasts through November 30, August and September have historically been peak months for the Pelican State.
Louisiana has a long history of damaging hurricanes. Between 2000 and 2020, the state has been struck by at least 28 tropical storms or hurricanes. These are a few hurricane facts
- In 1969, Hurricane Camille made landfall as a category 5 hurricane with wind speeds of up to 190 mph.
- In 2005, Hurricane Katrina also made landfall as a category 5 hurricane with wind speeds of up to 174mph. An estimated 80% of New Orleans was inundated. Millions of people were left homeless, around 1,800 people died, and the storm became the most expensive hurricane in US history, causing over $100 billion in damages.
- 2020 was the most active year with 5 storms affecting the state.
- Also in 2020, Hurricane Laura made landfall as a category 4 storm and had sustained wind speeds of 150 mph. The eye, which was about 25 miles wide, stalled over Lake Charles long enough to cause unprecedented devastation. Hurricane Laura killed 77 people and the costs were estimated at around $19 billion. Simply put, this storm was absolutely catastrophic.
If you live near the coast of Louisiana, you should definitely be putting some thought and action toward your hurricane preparedness plan. There are steps you can take now to mitigate future damage, such as installing shutters on your windows, or buying plywood and measuring it to the appropriate size of your windows.
Supplies can run out quickly and when a hurricane is forecasted you will have trouble finding certain items at the store, so make sure your emergency kits are also stocked beforehand.
If you live in the coastal region, be prepared for storm surge which is especially common during hurricanes and tropical storms. Learn about hurricane preparedness and safety here.
3. Severe Storms
Due to its climate, the Pelican State experiences severe weather in the form of thunderstorms, lightning, heavy localized rainfall, and occasional hail. A typical thunderstorm is 15 miles in diameter and lasts around 30 minutes. Nearly 10% of storms are classified as severe, meaning that they include high winds and hail of at least 3/4 inch in diameter.
Louisiana is the 2nd most lightning-prone state, averaging 827,000 cloud-to-ground lightning strikes per year. The summer months (June, July, and August) are peak months for lightning and thunderstorm activity.
Most lightning-related deaths in the state occurred because people were outdoors enjoying leisurely activities, such as sports and fishing. Lightning can strike more than 10 miles outside of the storm area, so when there’s a thunderstorm approaching, it’s best to take shelter indoors, preferably away from windows.

Louisiana experiences approximately 37 tornadoes each year and ranks 14th in the nation when it comes to its average number of tornadoes.
The strongest tornado outbreak in Louisiana occurred on February 7, 2017, and lasted a little over 13 hours. There were a total of 15 tornadoes, and the most damaging one was an EF 3 with wind speeds of up to 150 mph. That one struck New Orleans, injured 40 people, killed 1, and caused around $2.7 million in damages.
One of the deadliest tornado outbreaks in United States history occurred in Louisiana and neighboring states during April 24-26, 1908. A number of violent tornadoes moved through parts of Louisiana, Mississippi, and Alabama, killing 324 people and injuring 1,652 others. The city of Amite experienced the worst damage and 29 of its residents were killed.
Knowing where to take shelter before a tornado can be vital to your safety. In this guide, we discuss important mitigation strategies as well as what to do during the few minutes between when a tornado is predicted until after it passes. Although we cannot do anything about the intensity or destruction of such a natural event, there’s a lot we can do to lower our risk. Learn more here.
5. Extreme Heat and Drought
Louisiana has a humid and subtropical climate that creates a warm and muggy environment. It is ranked as the third hottest US state. New Orleans ranks 15th as the hottest city in the US.
Louisiana’s hottest month is August, where the highs range from 89°F to 94°F. The state’s position on the Gulf of Mexico gives it a wet season and high humidity that can make the heat feel like it’s 120°F. The hottest temperature ever recorded was 114°F on August 10, 1936, in Plain Dealing.
Louisiana averages 35 days of extreme heat but that number is expected to increase dramatically over the next 30 years. Over 160,000 people are currently vulnerable to extreme heat in the state.
Even though it rains a lot statewide, there are occasional periods of drought. According to the Drought Monitor, the longest duration of drought in the Pelican State lasted 107 weeks between April 2010 and May 2012. The most intense period occurred the week of June 21, 2011, where D4 (extreme drought) affected 64.94% of Louisiana land. As of the writing of this article, there is no drought.
6. Power Outages
Any natural disaster can cause extended power outages lasting from as little as a few hours to as long as months at a time. Two significant power outages occurred after hurricanes. After Katrina, nearly 28,900 utility poles were destroyed or knocked over and more than 2 million people were left without power. More recently in 2020, Hurricane Laura impacted nearly 900,000 customers.
A short-term power outage is inconvenient, but most people can adjust to a lack of electricity if it’s for a couple of hours. But what about 12 or more hours? And what if other factors are involved, like high heat and humidity or an ice storm? Natural disasters tend to have a domino effect on each other, so one intense storm can lead to numerous other issues, such as power outages.
This guide highlights everything you need to know to ensure that your preparedness plans are set long before an outage occurs. Be sure to print the checklists at the end and keep them in your emergency kit for future reference.
Each year approximately 1,431 wildfires are responsible for burning 14,950 acres throughout Louisiana. Fifty percent of Louisiana is forestland— that is about 14.9 million acres. Nearly 45% of the population, over 2 million people, lives at an elevated risk of wildfire.
While we weren’t born to remember this tragedy, New Orleans burned to the ground in 1788. Practically the entire city was consumed.
That event serves as a reminder of what can happen if a fire goes out of control. Simple practices can save your home or community from burning down. Know how to burn debris properly. Burn only when fire danger is low and never leave a flame unattended
8. Ice Storms
While this is not Louisiana’s greatest natural threat, one winter storm is expected to occur about once a year in the state. Freezing rain mixed with sleet and snow is rare but not out of the question.
In February 2021, an ice storm swept across southwestern Louisiana bringing frigid weather, temperatures in the single digits, and covering absolutely everything in a thick sheet of ice. This event halted transportation and caused rolling power outages leaving approximately 120,000 homes in the dark statewide.
Southeastern Louisiana has a moderate to high susceptibility of landslides, but low incidence. This might be because the point of highest elevation is only 535 ft. In any case, there is a higher possibility and occurrence along river banks and steep slopes, shifted sand, and muddy areas.
Severe weather may cause erosion and alter the topography of a region, thereby contributing to the possibility of landslides. Hurricane Harvey is a prime example that caused two landslides near the Louisiana and Texas border in 2017.
