Autumn is widely recognized as the “season of change,” as the environment undergoes visible transformations, including the alteration of leaf colors, the shortening and cooling of days, which in turn instigates shifts in animal migration patterns and concludes the growing season. Concurrently, the dog days of stagnant summer air are replaced by cool and breezy conditions. As we head into the autumn months, it’s a good time to review wind and wind-related products the National Weather Service can issue.
Larger differences in air masses during autumn can lead to stronger frontal passages and storm systems; it’s not uncommon for a strong low pressure system to move through with howling winds, only to depart leaving the trees bare of any color and leaves! These strong systems can cause structural damage and even injuries or, in rare circumstances, deaths. When wind speeds are sustained around 40 to 50 MPH, isolated wind damage is possible, like downed trees or branches, missing shingles or siding to homes, and downed power poles/lines. However, when higher wind speeds occur, even more significant damage is possible. A great example of this is when the remnants of Hurricane Helene moved through the Tennessee and Ohio Valleys last year. When a system like this moves through, the National Weather Service will issue Wind Advisories or High Wind Watches/Warnings. We’ll break down the differences in the wind related products below:
High Wind Watch:
Be Prepared! Sustained, strong winds are possible. Secure loose outdoor items and adjust plans as necessary so you’re not caught outside.
Wind Advisory:
Take Action! Strong winds are occurring but are not so strong as to warrant a High Wind Warning. Objects that are outdoors should be secured and caution should be taken if driving.
High Wind Warning:
Take Action! Sustained, strong winds with even stronger gusts are happening. Seek shelter. If you are driving, keep both hands on the wheels and slow down.
You can prepare for the strong winds ahead and hopefully prevent damage to your property, or worse, by taking the following steps:
- Trim tree branches away from your home and powerlines; secure loose gutters/shingles.
- Identify an interior room, such as a basement or interior bathroom, where you can take shelter during high wind events.
- Make a list of items outside of your home that you may need to bring inside or tie down so they don’t blow away or fly through a window. Additionally, have a plan for your livestock and any outdoor pets for high wind events.
- Have an emergency kit ready! Include items such as spare food, water, and medication to last up to three days for each person in your home: remember, roads may be impassible due to debris making pharmacy or grocery trips difficult or impossible. Plan to have a light source in case power goes out, such as a flashlight or candles.
