Storm Prep: Protecting Your Trees Before Tornado Season in Arkansas

Arkansas tornado season peaks from March through May, with secondary outbreaks in October and November. Fayetteville and the surrounding Washington County area sit in a particularly active corridor that has seen EF-3 and EF-4 tornadoes in recent memory, plus regular straight-line wind events with gusts over 70 mph. Every spring our crews respond to dozens of catastrophic tree failures that were preventable with a few hundred dollars of pre-season work. The window to protect your trees closes in mid-February. After that, the storms start coming and you are reacting rather than preparing. This article is the pre-storm checklist every NW Arkansas homeowner should walk through with an arborist by early March.

The Pre-Storm Inspection Checklist

Every tree near a structure should be inspected in late winter for six specific issues. First, deadwood: any dead branch over two inches in diameter is a missile in a storm. Second, co-dominant stems with included bark — V-shaped unions that look like two trunks fused together are the most common failure point in mature oaks. Third, decay pockets, cavities, or visible fungal conks indicating internal rot. Fourth, root flare problems — soil mounded over the buttress roots, recent grade changes, or visible heaving. Fifth, overextended laterals: long horizontal limbs with all their weight at the tip. Sixth, recent lean or any tilt that has changed since last year. Document everything with photographs.

Cabling and Bracing for Weak Crotches

Trees with structurally weak unions — typically co-dominant stems that have grown together with included bark trapped between them — are excellent candidates for cabling. A properly installed cable system links the two stems mechanically, redistributing the wind load and dramatically reducing the chance the union splits during a high-wind event. Modern dynamic cables, made from synthetic rope rather than steel, allow controlled movement that strengthens the union over time. Installation requires an ISA-certified arborist with rigging experience and follows ANSI A300 Part 3 standards. A single cable system runs $300 to $700 and can save a $30,000 tree.

Crown Thinning to Reduce Wind Resistance

A dense, sail-like canopy catches wind and transfers enormous load to the trunk and root system. Properly executed crown thinning — selectively removing small interior branches throughout the canopy — reduces wind resistance without compromising the structure or appearance of the tree. The target is 10 to 15 percent removal, never more, distributed evenly. Done wrong, thinning becomes 'lion-tailing' — stripping all the interior foliage and leaving only tufts at the branch tips — which concentrates weight at the wrong end of every limb and makes failure more likely. Insist on ANSI A300 standards and an ISA-certified arborist.

Removing Deadwood Before the First Storm

Deadwood removal is the highest-return pre-storm service. Dead branches over two inches in diameter will eventually come down on their own, usually in the next storm, usually at the worst possible moment. A professional crew can clear deadwood from a typical residential oak in an hour and the cost is modest. Walk your property in late February with binoculars and identify gray, leafless branches in the upper canopy of otherwise healthy trees. Mark them with flagging tape if needed. A pre-storm cleanup pass eliminates the single most common storm-damage source on most lots.

Which Tree Species Handle Wind Best in the Ozarks

Some species are inherently more wind-resistant than others. The strongest wind performers for NW Arkansas are white oak, post oak, shagbark hickory, southern magnolia, bald cypress, and Eastern red cedar. Moderate performers include red oak, sweetgum, and tulip poplar. The weakest performers — and the species that produce the highest share of storm damage we see — are silver maple, Bradford pear, hackberry, and willow. If you are planting new trees in NW Arkansas, choose from the strong-wind list and avoid the brittle species near structures.

After the Storm: Assessment and Insurance

Even with the best pre-season prep, storms produce damage. The first 24 hours after a severe event are critical. Stay clear of downed lines and any tree leaning on a power line. Photograph everything before any cleanup begins — wide shots and close-ups of every damaged tree, every limb on a structure, and any property damage. Call your homeowner's insurance carrier the same day to open a claim. Get a written estimate from a licensed, insured tree service before any work begins. We respond to storm calls in Fayetteville 24 hours a day at (479) 555-0183 and can document damage in a format that streamlines the insurance process.

A Practical Late-Winter Storm Prep Plan

For most Fayetteville properties, the smartest plan is simple. In January or February, schedule a full inspection of every tree that could hit a roof, driveway, fence, or play area. Have the arborist flag deadwood, overextended limbs, weak unions, and any trees showing root or trunk defects. Complete pruning and deadwood removal before March if possible, and install any recommended cables or braces before spring wind season begins. Refresh mulch rings, deep-water stressed trees if winter has been dry, and keep a folder of before-storm photos of the major trees on your lot. That last step helps tremendously with insurance documentation if a failure happens later. Storm prep is not about making trees storm-proof — nothing can do that in a direct tornado path — but it dramatically reduces preventable failures in the far more common straight-line wind and thunderstorm events we see every year in Northwest Arkansas.
