Severe Storms risk in Oklahoma

Severe Storm Characteristics in Oklahoma

Oklahoma is in the heart of what is commonly called Tornado Alley. This is because warm, moist air from the Gulf of Mexico regularly meets dry, cool air pushing south from the Rockies. The collision creates powerful thunderstorms capable of producing tornadoes, hailstones larger than baseballs, and straight-line winds exceeding 100 miles per hour. The NOAA Storm Prediction Center closely monitors Oklahoma because it sees more violent tornadoes than almost any other place on Earth. State agencies like the Oklahoma Department of Emergency Management provide local guidance for residents.

Severe storm season in Oklahoma runs mainly from late March through June, but storms can happen in every month. A second, lower peak often occurs in October and November as autumn cold fronts cross the Southern Plains. Storms tend to develop in the afternoon and evening, when temperatures are highest. While the tornado risk is greatest west of Interstate 35 and in central Oklahoma, the entire state is vulnerable to large hail and destructive winds.

Oklahoma thunderstorms also bring torrential rain, which can cause flash flooding. Although this page focuses on severe storm wind and hail risks, it is important to understand that a severe storm can include heavy rain and frequent lightning as well.

How It Affects Homes

Severe storms attack the exterior of a house first. Tornado-force winds can rip off roofs, break windows, and even destroy external walls. Large hail, often the size of golf balls or larger, can dent metal roofs, shatter skylights, and damage siding and gutters. Straight-line winds from a severe thunderstorm can be just as destructive as a weak tornado, tossing debris and tree limbs into homes.

Roof damage is the most common and expensive storm-related home repair. Once the roof covering is damaged, rain easily enters the attic and ceilings, causing secondary water damage, mold, and rot. Windows and sliding glass doors are particularly vulnerable to flying debris. Garage doors are also weak points: when a tornado or high wind hits a garage door, the pressure inside the home can push out walls and even lift the roof.

For insurance purposes, most standard homeowners policies cover wind and hail damage. In Oklahoma, however, some policies apply a separate wind and hail deductible, which may be a percentage of the home’s insured value rather than a flat dollar amount. It is important to review your policy with your agent to understand what your deductible is and how claims are paid. Flood damage is not covered by standard homeowners policies. Because severe storms can produce flash floods, homeowners who live in flood-prone areas should consider a separate flood insurance policy through the National Flood Insurance Program.

How to Prepare Your Home

Taking action before a storm arrives can make a major difference. Use these concrete steps from the National Weather Service and Ready.gov to reduce the risk of severe storm damage to your home.

• Inspect and reinforce your roof: Check for loose shingles, flashing, or rotten sheathing. Consider upgrading to impact-resistant shingles or a standing-seam metal roof that can better withstand hail.
• Install storm shutters or impact-resistant windows: These prevent wind and debris from breaking through glass and causing pressure changes inside the house.
• Strengthen your garage door: Use a reinforced garage door system or install bracing kits. The door should withstand high winds to prevent structural damage.
• Trim trees and remove dead branches: Loose branches and weakly rooted trees can become dangerous projectiles during a storm. Keep trees away from the house and utility lines.
• Secure outdoor items: Bring patio furniture, grills, planters, and trash cans inside or tie them down before a storm. Anything that can become airborne is a hazard.
• Designate a safe room: Pick an interior room on the lowest floor, such as a bathroom or closet, with no windows. If possible, install a FEMA-compliant safe room or storm shelter.
• Review your insurance coverage: Confirm that your policy covers wind, hail, and debris damage. Know your deductible and create a home inventory to make claims easier.

Frequently Asked Questions

What is the difference between a severe thunderstorm watch and a warning?

A watch means that conditions are favorable for severe storms to develop. You should be prepared to act. A warning means that severe weather is happening or imminent in your area. You should take shelter immediately. Pay attention to NOAA Weather Radio, local news, or smartphone alerts for warning notifications.

Is my home safe during a tornado if I don't have a basement?

No room is completely safe during a violent tornado, but an interior room farthest from exterior walls and windows is the best place. A bathroom, small closet, or hallway on the lowest floor reduces your exposure to wind and debris. If you do not have a basement, consider installing a storm shelter or FEMA-compliant safe room for improved protection.

Does homeowners insurance cover all severe storm damage?

Standard homeowners insurance in Oklahoma covers damage from wind and hail, including these severe storms. However, many policies have a separate wind and hail deductible. Flood damage from storms is not covered by standard policies, so you may need separate flood insurance if you live in a flood-prone area.
