Behind the Scenes with Knox County EMA:
Dead Trees, Dying Limbs, and Storm Season Preparedness
When severe thunderstorms, high winds, ice storms, or tornadoes impact Knox County, many people assume healthy trees are simply being overwhelmed by the weather. In reality, a significant portion of the tree-related damage we see after storms involves trees that were already dead, diseased, weakened, or structurally compromised before the storm arrived.
Strong winds often expose existing problems that may not be obvious during normal weather conditions.
Dead or deteriorating trees can create numerous hazards, including:
* Damage to homes, garages, barns, and other structures
* Downed power lines resulting in power outages
* Blocked roadways that delay emergency responders
* Damage to vehicles and farm equipment
* Injuries to residents, visitors, and utility workers
* Obstructed access routes during emergencies
What to Look For
Property owners should periodically inspect trees around homes, businesses, farms, and public gathering areas for signs of decline, including:
* Dead branches or limbs
* Hollow or decaying trunks
* Large cracks in the trunk or major limbs
* Mushrooms or fungal growth at the base
* Peeling or missing bark
* Significant leaning or root damage
* Trees with large sections lacking leaves during the growing season
If a tree appears unhealthy or presents a potential hazard, consider consulting a certified arborist or qualified tree service for an evaluation.
Before the Storm
One of the most effective mitigation measures a property owner can take is removing dead trees and trimming hazardous limbs before severe weather occurs.
Routine tree maintenance can:
* Reduce storm damage
* Protect power infrastructure
* Improve public safety
* Lower cleanup costs
* Reduce insurance claims
* Help keep roads open for emergency vehicles
During and After Storms
Never approach a tree that is touching or near power lines. Always assume downed lines are energized and dangerous. Report electrical hazards immediately to your utility provider and local authorities.
After severe weather, Knox County EMA works closely with local fire departments, highway departments, utility providers, public works agencies, and other partners to identify and address hazardous trees that impact public safety and critical infrastructure.
Preparedness Starts Before the Wind Blows
Storm preparedness is not just about having flashlights, weather radios, and emergency kits. It also includes reducing hazards around your property before severe weather arrives.
Taking time today to identify and address dead or weakened trees can help protect your family, your property, and your community when the next storm moves through Knox County.
