The short answer

Hurricane Wind Zones

Hurricanes bring sustained winds and storm surge along the Gulf Coast and the Atlantic seaboard. These storms develop over warm ocean waters and can affect coastal and inland areas hundreds of miles from the shore. Your home in a coastal region faces wind speeds that can exceed 100 miles per hour during a major event.

Preparation for hurricane winds includes reinforcing your roof, securing loose outdoor items, and checking windows and doors. You should also keep your gutters clear and trim weak branches near your house. In a coastal area like yours, the humid subtropical climate with hot rainy summers and an Atlantic hurricane season means you should have a plan for high winds and heavy rain.

  • Reinforce roof-to-wall connections
  • Install impact-resistant windows or shutters
  • Secure doors with heavy-duty bolts
  • Trim trees and remove dead branches
  • Store outdoor furniture and grills inside

Tornado Alley and Dixie Alley

Tornadoes form from severe thunderstorms and can occur in many parts of the country, but the highest frequency is in the central Plains and the Southeast. Tornado wind speeds can reach 200 miles per hour or more, though most are weaker. The risk extends across a broad swath of the central and southern United States.

For tornado-prone areas, the safest place is an interior room on the lowest floor without windows. You can also create a safe room that meets FEMA guidelines. Mobile homes are especially vulnerable, so you should have a plan to move to a sturdier shelter when a warning is issued.

  • Identify your safe room ahead of time
  • Keep a battery-powered weather radio
  • Practice tornado drills with your household
  • Secure heavy furniture and appliances to walls
  • Know the difference between a watch and a warning

Mountain and Downslope Winds

In mountainous regions, downslope winds can be extremely strong and localized. These winds occur when air flows over a mountain range and accelerates down the leeward side. Areas east of the Rockies, for example, experience chinook winds that have gusted above 100 miles per hour. These winds can cause sudden tree damage and roof uplift.

If you live near mountain passes or east of the Rockies, secure loose siding and roofing materials. Consider installing wind-resistant garage doors and reinforcing your chimney. You should also keep an eye on weather forecasts that mention high wind warnings for your specific area.

  • Reinforce garage doors with bracing
  • Check roof shingles and flashing regularly
  • Anchor sheds and outbuildings to the ground
  • Keep a supply of plywood for window protection

Thunderstorm Straight-Line Winds

Straight-line winds from thunderstorms can occur anywhere in the United States, but they are especially common in the Midwest and the Southeast. These winds, which can exceed 100 miles per hour, are often mistaken for tornadoes because they can cause similar damage. They typically last only a few minutes but can snap trees and damage roofs.

To protect your home from straight-line winds, maintain the structural integrity of your roof and walls. Check for loose or missing shingles after any severe storm. You should also have a plan for falling trees, including keeping large trees at a safe distance from your house.

  • Inspect roof edges and soffits for weakness
  • Use storm straps to secure roof trusses
  • Remove dead or leaning trees near the house
  • Install wind-resistant garage door tracks

Regional Preparation Strategies

Your preparation should match the wind risk in your region. Coastal areas need to focus on hurricane wind and water damage, while interior states should emphasize tornado safety and thunderstorm wind readiness. Mountain residents should pay attention to downslope wind events. No matter where you live, you should have an emergency kit with water, food, and essential supplies.

If a severe wind event damages your home, the first step is safety. Stay away from downed power lines and check for gas leaks. Then, document the damage with photos for your insurance claim. Policies vary, and your insurer decides what is covered. For water damage from wind-driven rain, you may need professional help to dry out your home and prevent mold.

Water damage does not wait

Water keeps spreading into floors and walls, so it is worth acting early. Calls are answered 24/7.

Frequently asked questions

What is the difference between a tornado watch and a warning?

A tornado watch means conditions are favorable for tornadoes to form, so you should be ready to act. A warning means a tornado has been sighted or indicated by radar, and you need to take shelter immediately. Always have a way to receive warnings, such as a weather app or a NOAA radio.

How can I tell if my roof can handle high winds?

Check for loose or missing shingles, and look at the condition of your roof deck and framing. Older homes may not have hurricane straps connecting the roof to the walls. A local building inspector or a structural engineer can assess your roof. You can also reinforce connections yourself with metal ties.

What should I do with outdoor furniture before a windstorm?

Move loose items inside if possible, including chairs, tables, and grills. If they are too heavy to move, anchor them to a deck or fence. Remove hanging plants and wind chimes. Also, secure trash cans and recycling bins. This prevents them from becoming projectiles that can damage your home or a neighbor's.
