Monsoon & High-Wind Tree Safety · Mesa & East Valley
Check trees from a safe distance before and after strong wind or heavy rain.
Arizona monsoon thunderstorms can produce damaging outflow winds, blowing debris, lightning, dust, and flash flooding. The National Weather Service Phoenix office notes that the strongest thunderstorm wind gusts can exceed 100 mph, and the City of Mesa advises evaluating large trees close to homes when high winds combine with saturated ground.
Watch for broken or hanging limbs, a new lean, lifting or cracking soil near the trunk, fresh trunk splits, root movement, or large damaged branches over a roof, wall, driveway, pool, or walkway. Avoid standing under a damaged tree while inspecting it.
Power-line safety comes first. Bynum Tree and Landscape does not accept tree work involving active power lines. SRP advises staying well clear of downed lines and contacting the utility for trees growing too close to power lines. For SRP power emergencies, fallen lines, arcing, or damaged electrical facilities, call (602) 236-8811.
Summer pruning should be species- and condition-specific. University of Arizona Cooperative Extension advises against heavy summer pruning of most trees unless storm-damaged, while mesquite and palo verde can be pruned during hot weather because they heal well in the heat. Proper pruning should preserve useful canopy and avoid topping or unnecessary over-thinning.
