In Oklahoma, the weather does not ask for permission. The atmosphere can shift from a sunny afternoon to a supercell event in a matter of minutes. For residents of Tornado Alley, understanding the progression of a storm is not just meteorological trivia—it is a survival skill.
However, knowing the weather is only half the battle. The other half is knowing that your protection can withstand whatever the radar indicates. At Oklahoma Shelters, we specialize in engineering peace of mind. Our FEMA-rated concrete shelters are designed to endure the full spectrum of chaotic weather, from the first gust of wind to the catastrophic force of an EF5 wedge tornado.
Here is a breakdown of the three degrees of storm intensity and how a reinforced concrete shelter performs at every critical stage.
Stage 1: Moderate Storms – Built for Confidence
The first degree of storm intensity often begins with a “Watch.” The sky darkens, the wind picks up, and local news stations break into regular programming. At this stage, wind speeds may range from 60 to 80 mph. While this might not level a house, it can snap tree limbs, toss patio furniture, and cause power outages.
How the Shelter Performs: During moderate storms, the primary role of an Oklahoma Shelters concrete unit is psychological security. The structural integrity of a concrete shelter is absolute against these lower-tier winds.
Dry and Secure: Our shelters are sealed against heavy rain and driving winds.
The “Wait and See” Zone: This is the time to prep. Because you know the shelter is ready, you don’t need to panic. You can calmly gather your family, check your weather radio, and stay alert.
Action Plan: Use this stage to clear the path to your shelter. Ensure the door is accessible and your emergency supplies are inside.
Stage 2: Severe Tornado Warnings – Tested Protection
The atmosphere shifts violently. The “Watch” becomes a “Warning.” Sirens begin to wail across the county, and meteorologists identify distinct rotation on the radar. At this degree of intensity, we are looking at potential EF1 to EF3 tornadoes. Wind speeds can exceed 135 mph.
How the Shelter Performs: This is where the engineering of reinforced concrete and steel proves its worth. A standard residential home begins to fail at this stage—roof shingles peel off, windows shatter from pressure differentials, and exterior walls may buckle.
Debris Deflection: The greatest danger in a severe tornado is not the wind itself, but what the wind is carrying. Our steel doors and concrete walls are engineered to withstand high-velocity impact from flying debris (2x4s, branches, and metal siding).
Pressure Management: The shelter handles the extreme drop in barometric pressure without compromising its seal.
Action Plan: Time is critical. Do not watch from the porch. Move your family and pets into the shelter immediately and lock the hydraulic-assisted door.
Stage 3: Extreme Tornado Events – Life-Saving Defense
This is the nightmare scenario. The “Grinder.” The EF4 or EF5 event. These are the storms that scour pavement and level neighborhoods to the foundation. Wind speeds surpass 200 mph, and the destruction is total.
How the Shelter Performs: In an extreme event, a standard home offers effectively zero protection. An interior closet or bathtub is no longer safe. Only a concrete storm shelter offers true life-saving defense.
Immovable Object: When an entire neighborhood is destroyed, the only things left standing are often the concrete storm shelters. Our units are anchored to resist the immense lift and drag forces of an EF5 vortex.
Ultimate Survival: This stage is why we follow strict FEMA guidelines. The walls are designed to prevent penetration from heavy projectiles (like cars or structural beams) that are tossed around like toys.
Action Plan: If you are in the path of an extreme event, every second is a matter of life and death. You must be inside the shelter with the door secured before the debris ball arrives.
