Winter Storms risk in Mississippi

Winter weather in Mississippi: what to expect

Mississippi has a humid subtropical climate, and most winters pass with little or no frozen precipitation. That is why the state sits at a relatively low level for winter storm risk compared with states farther north. But low risk does not mean no risk. When cold air pushes south from the Plains and moisture moves in from the Gulf of Mexico, Mississippi can get ice.

In Mississippi, winter storms are usually ice storms rather than heavy snowstorms. Freezing rain and sleet can coat trees, power lines, bridges and overpasses with a glaze that may be only a tenth to a half inch thick. That is enough to matter: ice is heavy, and a quarter inch on a tree limb or a power line can cause it to snap. In this climate, a light ice accumulation is often more damaging than several inches of dry snow would be.

Where and when risk is highest

• Northern Mississippi — Corinth, Tupelo, Oxford, Holly Springs and the northern Delta — sees the most winter weather. Light snow accumulations and freezing rain are most likely here.
• Central Mississippi — including Jackson, Vicksburg and Meridian — gets occasional ice events and rare light snow.
• The Gulf Coast — Gulfport, Biloxi and Pascagoula — almost never sees measurable snow or ice, although cold rain, strong wind and hard freezes do occur.
• Season: winter weather in Mississippi generally falls between December and March, with January and February the most likely months.

Two related hazards matter as much as the frozen precipitation itself: ice on bridges and overpasses, which freeze before the road surface around them, and wind chill during the cold-air outbreaks that follow a front.

How it affects homes

Winter damage in Mississippi usually arrives in one of three ways: ice loading on trees and branches, power outages that leave a home cold, and frozen plumbing. Even a short, shallow freeze can burst an uninsulated pipe in a crawl space, attic or exterior wall — and the resulting water damage is often far more expensive than the weather event itself.

• Falling limbs and trees. Ice-weighted branches drop onto roofs, gutters, vehicles and power lines. This is the most common structural damage in a Mississippi ice event.
• Frozen and burst pipes. A leading cause of winter property claims, especially in older homes and manufactured housing with exposed plumbing.
• Loss of heat during outages. Multi-day power failures are possible after an ice storm, which puts both pipes and people at risk.
• Roof and gutter damage. Ice can loosen flashing and shingles and pull gutters away from the fascia.
• Slip-and-fall injuries on icy driveways, steps and walkways.

On insurance: most standard homeowners policies in Mississippi cover sudden damage from the weight of ice or snow, from a tree or limb that falls on the house, and from a pipe that freezes and bursts — provided the home was reasonably maintained. Policies vary, so it is worth confirming the details before winter. Points to check:

• Many policies exclude or limit freezing of plumbing if the home was vacant or unheated. Keep the heat on and have someone check an empty home.
• Water damage from snowmelt flooding is generally not covered by a standard homeowners policy; that requires separate flood insurance.
• Many policies include limited reimbursement for food spoilage after a power outage, so check your limit.
• A limb that damages your car is typically handled under the comprehensive portion of an auto policy.
• Photograph damage before you clean up, save receipts, and report claims promptly.

How to prepare your home

1. Protect your pipes. Insulate exposed pipes in crawl spaces, attics, garages and along exterior walls. Disconnect garden hoses, shut off and drain outdoor spigots, and when a hard freeze is forecast, let an interior faucet drip and open cabinet doors under sinks on exterior walls.
2. Know where your main water shut-off is so you can stop the flow fast if a pipe bursts.
3. Trim trees and clean gutters. Remove dead or overhanging limbs above the roof, driveway and service lines before winter.
4. Insulate and air-seal. Add attic insulation, weatherstrip doors and windows, and seal gaps around pipes and vents to hold heat in.
5. Plan for power outages. Keep flashlights, batteries, blankets, water, non-perishable food, a battery-powered radio and charged phones. If you use a generator, run it outdoors only, well away from windows and doors — never inside a home or garage.
6. Install carbon monoxide alarms anywhere you use a fuel-burning heat source or a generator.
7. Check the roof. Repair loose shingles and flashing; high wind and ice find weak points first.
8. Build a cold-weather car kit and keep the gas tank at least half full.
9. Review your coverage and keep an updated home inventory with photos.

Frequently asked questions

Does it snow in Mississippi?

Yes, but not often and not much. Light snow is most common in the northern third of the state, where a few inches can accumulate during a strong cold outbreak. Central Mississippi sees occasional dustings, and measurable snow on the Gulf Coast is very rare. Ice — freezing rain and sleet — is a more frequent winter visitor than deep snow.

What is the biggest winter storm threat in Mississippi?

Ice and its side effects. Freezing rain coats trees and power lines, which can snap under the weight and cause widespread, sometimes multi-day outages. The cold that follows creates the second threat: frozen and burst water pipes, which are one of the most common and costly winter claims in the state.

Does homeowners insurance cover winter storm damage in Mississippi?

Often, yes. Standard policies commonly cover sudden damage from the weight of ice or snow, from a falling tree or limb, and from a pipe that freezes and bursts, subject to your deductible. Coverage can be reduced or denied if a home was left unheated or vacant, and flood damage from snowmelt is not covered under a standard policy. Review your own policy wording or ask your agent.
