Mississippi Water and Flood Damage Restoration, Coast to Delta

Mississippi's Rainfall Runs From North to Coast

Mississippi averages about 56 inches of rain a year, ranging from about 50 inches in the north to about 65 inches on the coast. The climate is humid subtropical, with mild winters, hot summers and rain in every season.

That steady moisture means wet building materials don't dry out on their own very well. Mold can begin growing within 24 to 48 hours on soaked drywall, carpet and wood, so water extraction and drying should begin promptly.

Hurricane season lasts from June 1 to November 30, with most activity typically between mid-August and October. Hancock, Harrison and Jackson counties face the highest surge risk, but storms such as Ida in 2021 carried wind and flooding rain far inland.

Surge, Rivers and Tornadoes

Some of the nation's most surge-prone coastline

Camille produced a 22.6-foot surge at Pass Christian in 1969, and Katrina topped it with 27.8 feet in 2005. Surges of 20 feet or more are expected every 50 to 100 years on this coast.

River flooding

The Pearl River at Jackson crested at 36.67 feet on February 17, 2020, after 72 hours of heavy rain on saturated ground. Along the western edge of the state, the Mississippi River is the major flood threat; the historic spring 2011 flood caused more than $500 million in agricultural damage in Mississippi alone.

Tornadoes and severe storms

Mississippi averaged 46 tornadoes a year from 1985 to 2019 and ranks first nationally in tornado deaths per capita over that period. Wind damage to roofs and walls lets rain in, so storm damage cleanup often goes hand in hand with drying out the interior.

Why the type of water matters

Restoration companies use IICRC S500 categories to plan a job. A burst supply line is usually Category 1, clean water. Overflow from a washer or dishwasher is Category 2, gray water. Surge, river floodwater and sewage are Category 3, grossly contaminated water, which typically means tearing out soaked drywall, insulation and carpet instead of drying them in place. Knowing the category helps you understand the scope and estimate you're given.

Regional Risks Across Mississippi

The Gulf Coast. Gulfport, Biloxi, Ocean Springs, Pascagoula, Long Beach, Bay St. Louis and Waveland face extreme surge risk, and surges of 15 feet or more have about a 25-year average return period. Our Gulfport water damage page covers the coast in more detail.

Jackson metro. Jackson, Pearl, Brandon, Ridgeland, Madison and Clinton sit near the Pearl River, where flooding is the main concern. The 2020 crest showed how long, soaking rain on already saturated ground can push the river into neighborhoods.

Pine Belt and South Mississippi. Hattiesburg, Petal, Laurel and Picayune catch heavy rain and wind from hurricanes that land in Louisiana or Mississippi. Ida dropped 13.65 inches of rain near Kiln.

River and Delta region. Vicksburg, Natchez and Greenville live with the Mississippi River and its flood seasons.

North Mississippi. Southaven, Olive Branch, Tupelo, Oxford, Starkville, Columbus and Meridian see heavy thunderstorms, flash flooding and tornadoes more than tropical surge. Here, roof damage and flash flooding of low-lying streets and yards are the usual paths for water to get inside.

Past Floods and Hurricanes in Mississippi

• Hurricane Camille (1969): a Category 5 with more than $900 million in damage in Mississippi.
• Hurricane Katrina (2005): extensive coastal and inland damage and 238 deaths in Mississippi.
• Mississippi River flood (2011): record upstream snowmelt and rainfall drove historic spring flooding.
• Pearl River flood (2020): the river's highest peak at Jackson since 1983 and the fourth highest since records began in 1901.
• Hurricane Ida (2021): kept hurricane-strength winds into southwest Mississippi near McComb.

Events like these leave behind months of flood damage restoration work across whole communities. They're also a reminder to keep important documents, insurance details and a restoration contact number somewhere you can reach quickly.

Verifying a Contractor in Mississippi

The Mississippi State Board of Contractors (MSBOC) licenses commercial and residential contractors and roofers. Before signing a repair contract, look the company up with the board's online contractor search or call the board at 800-880-6161.

For mold cleanup, ask the company about its training and certifications, such as IICRC, and request written moisture and clearance documentation at the end of the job. A reputable company should also be able to show proof of insurance and explain how it will contain the work area. Learn more on our mold removal page.

Flood Policies and Paperwork

Your regular homeowners policy almost certainly excludes flood. You need an NFIP or private flood policy, and a new NFIP policy generally has a 30-day waiting period, so buy it well before storm season or a forecast river crest.

• If you live near the Pearl River in the Jackson metro, watch NWS river forecasts for the Pearl River at Jackson during long stretches of heavy rain.
• After a hurricane or tornado, photograph all damage before cleanup.
• Keep receipts for emergency repairs such as tarping and water extraction.
• Make a room-by-room list of damaged belongings, and don't throw items away until your adjuster says it's OK or you've photographed them.
