Sewage backups in Mississippi County spike on heavy-rain days, about 15.2 a year, when sewer mains fill up and water finds the lowest drain.
Mississippi County's wettest day in the 2015–2024 record brought 3.74 inches, and about 42 freeze-thaw days a year mean ice dams in some winters.
5% of occupied homes in Mississippi County heat mainly with wood or propane, below the Arkansas county median of 10.9%.

Local risk profile
Mississippi County covers 902 square miles of northeast Arkansas, with about 39,126 residents and 19,133 homes. Besides Blytheville, the county seat, the biggest communities are Osceola, Manila and Gosnell. The county's median home was built in 1977.
53/100 Water Damage Risk Index: Elevated Mississippi County ranks 34 of 75 Arkansas counties. See the statewide ranking and method.The three factors where Mississippi County ranks highest compared with other Arkansas counties.
For frozen pipes, Mississippi County is a typical Arkansas county, which is still plenty. In the 2015–2024 record the county logged about 8 nights a year at or below 20°F (29th of 75) and 48 below freezing. Twenty degrees is roughly where uninsulated pipes start to freeze.
On December 23, 2022 the low fell to about -1°F, and in the stretch ending February 2021 the county went 9 days in a row below freezing. Leaks from split pipes typically appear the day the thaw arrives.
Most freezing nights fall from January to February, peaking in January. Disconnect garden hoses and shut off outdoor spigots before the first hard frost, and keep the heat at 55°F or higher if you'll be away.
On average the first fall freeze arrives around Nov 12 and the last spring freeze around Mar 21.
Mississippi gets fewer downpours than most Arkansas counties, but they still fill basements. Of roughly 54.2 inches of yearly precipitation, the damage comes from the 15.2 days a year with an inch or more, ranked 55th of 75. February, March and April see the most. The single wettest day in the record: 3.74 inches, March 10, 2016. Multi-day storms matter most for basements; the wettest three days on record here totaled 5.92 inches (through March 11, 2016).
The temperature crosses 32°F in both directions on roughly 42 days a year. Each cycle melts and refreezes water at roof edges and in foundation cracks, which is how ice dams and basement seepage get started.
Housing
Roughly 57% of the county's housing was built before 1980. That puts Mississippi among the oldest housing stocks of Arkansas's 75 counties.
Housing age is mixed: 18% of homes are pre-1960 and 15% are 2000 or newer. Ask any plumber which era your house is from and you'll know which failures to watch for.
28% date from 1980 to 1999, the window when polybutylene, a gray flexible plastic supply pipe, was used in some homes. It's prone to leaks at the fittings, so it's worth checking for in a house from those years.
Manufactured and mobile homes make up 7% of the housing here. Water lines in the underbelly depend on intact skirting and working heat tape, and they're usually the first to freeze in a cold snap.
Renters occupy 40% of homes. If you rent, the building is usually the landlord's to repair, but your belongings are only covered by renters insurance.
Beyond water
About 109 nights a year in Mississippi County stay at 65°F or warmer, a sign of muggy summer air (28th of 75 counties). March is the wettest month. The EPA recommends keeping indoor humidity below 60%, ideally 30 to 50%. Basements can pass 60% on their own in summer, so a dehumidifier matters even without a leak, and anything wet should be dried within 24 to 48 hours.
Mold remediation: what to expectHeating fuel matters for fire risk. In Mississippi County it's 50% utility gas, 44% electric, 5% propane and under 1% wood. Heating equipment, cooking and electrical failures cause most home fires nationally. Even a small kitchen fire can leave soot through the whole house, because smoke follows air currents into closets, ducts and attic space.
