Hurricane season is a significant annual concern for coastal communities, particularly New Orleans. Understanding when it occurs and how to prepare is important for safety and planning.
Understanding the New Orleans Hurricane Season
The official Atlantic hurricane season spans from June 1st through November 30th. During this six-month window, tropical cyclones are most likely to form in the North Atlantic Ocean.
New Orleans faces vulnerability due to its unique geography. Much of the city is situated below sea level, with some areas ten feet lower than surrounding water bodies. Its “bowl-like” topography, bordered by the Mississippi River and Lake Pontchartrain, creates conditions where heavy rains or storm surges can lead to flooding. The region’s unconsolidated, organic soils also contribute to subsidence, further lowering land elevation over time.
The peak of the Atlantic hurricane season typically occurs from late August through September, with September 10th marking the climatological midpoint of activity. For New Orleans, the period from mid-August to mid-October generally sees the most intense activity.
Preparing for Hurricane Season
Preparation for hurricane season involves several steps. Creating a comprehensive family emergency plan is a foundational element, outlining where to go, how to get there, and what items to bring in case of an evacuation. This plan should also account for any special needs within the family and include provisions for pets.
Assembling a disaster supply kit is another important measure. This kit should contain at least a three-day supply of non-perishable food and one gallon of water per person per day for drinking and sanitation. Other essential items include a first-aid kit, a week’s supply of prescription medications, a battery-operated radio, a flashlight with extra batteries, and important documents stored in a waterproof container. Keeping some cash on hand and sanitation supplies is also advised.
Understanding evacuation routes and orders is important for safety. New Orleans city officials may issue mandatory evacuation orders, particularly if the region is directly threatened by a Category 3 hurricane or stronger. In such situations, all residents and visitors are required to leave. Familiarity with contraflow routes, which direct all lanes of traffic away from the city, can help manage traffic during large-scale evacuations.
Staying informed through official channels provides timely and accurate information during a storm. Local news broadcasts, NOAA Weather Radio, and city alert systems are reliable sources for updates on storm progress, potential evacuation orders, and shelter locations.
