A tornado hit a town about 60 miles from me two or three springs ago. EF3. One neighborhood was leveled. The family in the FEMA-rated safe room walked out without a scratch. The family next door, sheltering in an interior closet, survived but with injuries from debris that penetrated the walls. Same tornado. Different outcomes based entirely on where they sheltered.

Here's what I've got today.

Storm Shelters: When the Interior Closet Isn't Enough

We covered severe weather preparation in Issue 26, including the standard advice: go to the lowest floor, interior room, away from windows. That advice is good. For most tornadoes, it's sufficient. But for strong tornadoes (EF3 and above), interior rooms in wood-frame homes can fail. Walls collapse. Roofs lift off. Debris penetrates ordinary construction.

A dedicated storm shelter or safe room provides near-absolute protection. FEMA publishes construction standards (FEMA P-320 and P-361) for residential safe rooms designed to withstand 250 mph winds and resist penetration from wind-borne debris. These standards cover both above-ground reinforced rooms and below-ground shelters.

Below-ground shelters are the most common and most affordable. A concrete or fiberglass in-ground shelter installed in a garage floor or backyard costs $3,000 to $8,000 depending on size and material. They hold 4 to 8 people and are accessed through a hatch. Installation takes one to two days. These provide the highest protection level because they're below the debris field.

Above-ground safe rooms are reinforced rooms built inside your home, typically in a garage, closet, or bathroom. They're constructed with steel-reinforced concrete or welded steel panels and meet the same FEMA wind resistance standards. Cost: $6,000 to $15,000 depending on size. The advantage: accessibility for people with mobility limitations who can't descend into an underground shelter.

Retrofit options exist for existing homes. Companies manufacture bolt-together steel safe rooms that install inside an existing garage in a few hours. These are less expensive than poured concrete ($3,000 to $6,000) and can be taken with you if you move.

FEMA grants through the Hazard Mitigation Grant Program (HMGP) can cover 75% of the cost in eligible areas. Check with your state emergency management agency for availability.

For most readers in tornado-prone regions, the realistic progression is: first, identify your best existing shelter area (Issue 26). Second, improve it (reinforce an interior closet with plywood and lag screws). Third, when budget allows, install a dedicated shelter or safe room.

If a dedicated shelter isn't feasible, helmets (bicycle helmets work) and shoes near your shelter area remain the most cost-effective life-safety upgrades. Head injuries are the leading cause of tornado fatalities.

The Deadliest Tornado Outbreak Since 2011 Just Hit the Upper Midwest, Not the South

A super outbreak on May 13 and 14 produced 206 tornadoes across 12 states, killed 78 people, and injured more than 1,700, the deadliest US tornado event since 2011. May 13 alone produced 162 tornadoes in 24 hours, the second-highest single-day count on record. The most violent tornado, rated EF5 with winds exceeding 205 mph, cut a 22.3-mile path through Rochester, Minnesota. It was the state's first EF5 ever and only the second EF5 rated anywhere in the US since 2013.

Why it's on our radar: this outbreak hit the upper Midwest, not the traditional Tornado Alley or Dixie Alley corridors. Violent, EF4-plus tornadoes are no longer confined to the states people expect them.

Jessie Krebs' SERE instruction career taught her that shelter is the most immediate survival priority after a threat assessment. On Hacking the Wild, she demonstrated that the quality of your shelter determines your survival timeline in every environment.

For tornado preparedness, Krebs' principle translates directly: the strength of your shelter determines your outcome. An interior closet is a shelter. A FEMA-rated safe room is a fortress. The gap between them is the gap between survivable and unsurvivable for the strongest tornadoes. Know which one you have, and plan accordingly.

U.S. Uses Robot Boats and Kamikaze Drones Against Iran for the First Time in Combat

U.S. Central Command confirmed it used unmanned systems in direct combat against Iran for the first time this weekend. Three 24-foot Corsair autonomous sea drones, built by Texas-based Saronic, struck a submarine and a ship maintenance facility at Iran's Bandar Abbas Naval Base in the Strait of Hormuz. The U.S. also fired one-way attack aerial drones in the same wave of strikes. CENTCOM said the attack degraded Iran's ability to keep targeting commercial shipping through the strait. The strikes followed Washington's July 7 decision to revoke Iran's oil-export license and President Trump's declaration that the ceasefire in place since April was over.

A widening conflict tied to the Strait of Hormuz, the passage for roughly a fifth of the world's oil, means continued volatility in fuel prices and shipping-dependent goods. Households that depend on imported fuel or goods routed through the region should expect prices and availability to keep swinging as this continues.

Survive-A-Storm Twister Pod (Above-Ground Safe Room)

This is a bolt-together steel safe room designed for garage installation. It holds 4 to 6 people, meets FEMA P-320 standards for 250 mph wind resistance, and bolts to a concrete garage floor. I helped a friend install one. The assembly took about 4 hours with two people and basic tools.

The interior is sparse: bench seating, ventilation ports, and anchor points. It's not comfortable for extended stays, but it doesn't need to be. Tornado shelter duration is measured in minutes, not hours.

Testing (as much as one can test a tornado shelter): the welds are solid, the bolts are rated, and the door seals tightly. The real test is the one nobody wants. About $3,850 for the 4-person model.

Budget alternative: Reinforce an existing interior closet with 3/4-inch plywood and 3-inch lag screws into the studs. Add a bicycle helmet for each family member. Total: about $100. Not FEMA-rated, but meaningfully stronger than unmodified construction.

Overrated: Bathtubs as tornado shelters. The old advice to "get in the tub and cover with a mattress" is better than standing by a window, but bathtubs offer minimal structural protection in a strong tornado. An interior closet is better. A safe room is dramatically better.

Underrated: FEMA safe room grants. Many people don't know these exist. The Hazard Mitigation Grant Program can cover up to 75% of the cost of a residential safe room in qualifying areas. One phone call to your state emergency management office tells you if you're eligible.

PS: The family in the safe room told me later that the noise was "like standing inside a drum while someone hit it with a truck." Ten seconds of absolute terror. Then silence. Then they opened the door to a neighborhood that was unrecognizable. But they walked out. That's what $3,850 bought them.
