Gusty winds are great for flying kites, windsurfing and hoisting flags, but they’re not all fun and games. High winds can bring down power lines, cause property damage and pose life-threatening dangers to people and pets. It’s important to understand the causes of windstorms, and what you can do to mitigate any damage they might create. Staying safe and minimizing wind damage is a matter of staying alert and responding quickly when high winds are present or predicted.
We expect high winds during stormy weather or high-profile storms like tropical storms and hurricanes. But dangerously high winds can occur even on a clear day, because the causes of windstorms all come down to temperature.
Gas particles bundle tightly together in cold air and spread out as the air warms, which is why you may hear masses of cold and warm air referred to as “high pressure systems” and “low pressure systems,” respectively. When these systems collide, air rushes from the high pressure area to the low pressure area, creating wind. The greater the pressure difference, the faster the wind.
Heavy winds are typically formed by atmospheric pressure variations, which cause gusts of air to rush in to fill low-pressure zones. Additionally, wind can result from heavy activity in the jet-stream high in the sky. Finally, large fronts of cold air can also provoke turbulence in the atmosphere. When all those conditions combine, you could be in for winds that endure for days.
While wind is a frequent, and usually benign, natural phenomenon, the effects of windstorms do have potential to cause harm to you and your home, either on their own or in conjunction with other weather conditions. Read on for tips on how to prepare for a major windstorm, and what to do if one does arrive in your town.
The National Weather Service issues a range of wind alerts when high winds are predicted or occurring. Because some areas of the U.S. are naturally windier than others, these warnings may be triggered at different wind speed levels in one place than in another. Every National Weather Service forecasting office has its own regional criteria for wind alerts.
These alerts include:
For smartphone users, the easiest way to keep tabs on all severe weather alerts is to download a weather app that offers alert notifications.
Property is replaceable, but there’s only one you. When there’s no time to batten down the hatches, the most important thing is to make sure you and your family are safe until the winds die down.
The damaging effects of windstorms can range from broken flower pots to having your roof torn off. Here are some ways you can protect your property:
A nice breeze is a welcome arrival on a stifling summer day, but when the thermometer drops in the winter months, wind can contribute to uncomfortable, and possibly dangerous, conditions. That’s because high winds provoke chills by causing you to lose body heat at a much faster rate than you would normally expect to at a given temperature in non-windy conditions. This effect works primarily through convection, when the warmth is transferred out of your body and onto the fast-moving air molecules. You’ve probably heard of the wind chill factor – when it feels much colder outside than the thermometer would have you believe.
For example, according to the National Oceanic and Atmospheric Administration, on a 30 degree day, just five mph of wind can make it feel like 25 degrees out. If that wind picks up to 30 mph, it will feel like 15 degrees, a considerably chillier experience. The colder the actual temperature, the more acute the wind chill effect, which at extreme levels can lead to frostbite and other medical emergencies like hypothermia. If you have to venture outside, make sure you know what to do during wind chills.
Wind can cause plenty of damage on its own, but it often arrives hand-in-hand with other forms of nasty weather that can compound the danger. Straight-line wind that precedes a thunderstorm is known as a derecho and can create considerable chaos even before the heavy rains and lightning bolts arrive on the scene.
If the windstorm comes in wintertime and is accompanied by heavy snowfall that limits visibility, it’s likely to be classified as a blizzard, which carries its own set of precautions you should take to ensure the safety and security of your home and family.
Depending on where you live, you may be subject to extreme wind-related weather events such as hurricanes or tornadoes, which are life-threatening occurrences that may require more intense emergency preparation up to and including evacuation. Please follow all instructions from local officials if you are unfortunate enough to experience such a disaster and make the safety of your family your number one priority.
High winds and wildfire are also a deadly combination, as the massive conflagrations that have overrun large swaths of the western United States the past few years have demonstrated. If you find yourself in the path of an uncontrolled wildfire, again, it’s imperative to vacate the area immediately and follow the guidance of the appropriate authority figures.
