Late summer brings intense thunderstorms, high winds, and sudden downpours to Spokane and Northern Idaho — conditions that test every outdoor electrical component on your property. Proactive outdoor electrical maintenance before storm season protects expensive equipment, prevents dangerous faults, and keeps your family safe when severe weather strikes. As your source for Outdoor & Lifestyle Electrical Solutions in Spokane & Northern Idaho, Evergreen Electric PNW prepares homes across the region with storm electrical safety inspections and weatherproof electrical upgrades that stand up to whatever nature delivers.
Why Late Summer Storms Threaten Outdoor Electrical Systems
Spokane’s late summer storm season combines lightning, high winds, heavy rain, and occasionally hail — each posing distinct threats to outdoor electrical infrastructure. Lightning strikes cause massive voltage surges that destroy unprotected electronics and can ignite wiring. High winds snap tree branches onto power lines and outdoor fixtures. Driving rain penetrates damaged covers, corroded boxes, and compromised seals.
Outdoor wiring, fixtures, and equipment absorb months of summer heat and UV exposure before storm season arrives, weakening insulation and gaskets precisely when they need to perform at their best. Components that survived winter and spring may fail under the combined stress of heat degradation and storm exposure.
The cost of storm-related electrical damage far exceeds the cost of preventive maintenance. A single lightning surge can destroy thousands of dollars in electronics and appliances. A ground fault caused by water intrusion into a damaged junction box can create shock hazards that endanger family members. Investing in outdoor electrical maintenance before storms arrive eliminates these risks at a fraction of the repair cost.
Storm Electrical Safety Inspection Checklist
Complete these essential storm electrical safety checks before severe weather season begins:
Inspect all outdoor junction boxes and covers. Look for cracks, missing gaskets, rust, and loose fasteners. Replace any damaged cover with a weatherproof in-use cover that protects outlets even when cords remain plugged in.
Check all outdoor wiring and conduit. Walk the perimeter of your property and trace every visible conduit run. Look for separated joints, cracked PVC, corroded metallic conduit, and any sections pulled loose from their mounting hardware by wind or settling.
Test every GFCI device. Press the test button on each GFCI outlet and breaker protecting outdoor circuits. Any device that fails to trip requires immediate replacement. Storm conditions amplify ground fault risks enormously, making functional GFCI protection critical.
Verify surge protection. Check that your whole-home surge protector indicator light shows active protection. Surge protectors degrade after absorbing previous surges and may offer diminished protection without any visible sign of failure. Replace any unit older than five years or one that has absorbed a known major surge.
Examine landscape lighting transformers. Ensure transformer enclosures remain sealed, ventilated, and elevated above potential flood levels. Water intrusion into a transformer creates shock hazards and destroys the unit.
In our post on Outdoor Security Lighting for Spokane Homes, we discussed how strategic fixture placement improves safety — protecting those fixtures from storm damage ensures they perform when you need them most.
Weatherproof Electrical Upgrades That Prevent Damage
Several weatherproof electrical upgrades dramatically reduce storm-related damage risk:
Whole-home surge protection installs at your main electrical panel and intercepts lightning-induced voltage spikes before they reach interior wiring and connected devices. These devices clamp surges to safe levels within nanoseconds, protecting everything from your HVAC system to smart home controllers. Pair panel-mounted surge protection with point-of-use protectors at sensitive electronics for layered defense.
Weatherproof in-use covers replace outdated flat spring covers on all outdoor outlets. In-use covers maintain their weatherproof seal even with cords plugged in — essential during storms when rain drives horizontally into surfaces that vertical-mount outlets face.
Sealed and gasketed junction boxes replace deteriorated outdoor boxes where wiring connections live. Marine-grade boxes with compression fittings and silicone gaskets prevent water from reaching wire connections even during prolonged heavy rain.
Underground wiring upgrades replace exposed overhead wire runs between structures with buried conduit. Underground wiring eliminates the wind and ice damage risk that overhead runs face during storms. A licensed electrician selects the correct burial depth and conduit type for Spokane’s soil and frost conditions.
GFCI breakers at the panel provide centralized ground fault protection for entire outdoor circuits. Panel-mounted GFCIs protect every outlet and fixture on the circuit without relying on individual GFCI receptacles that may fail independently.
Protecting Outdoor Equipment During Severe Weather
Beyond fixed wiring, outdoor electrical equipment needs storm preparation:
Portable generators must sit in dry, ventilated locations during storms. Never operate a generator in rain without a properly rated generator cover or shelter. Water on a running generator creates lethal electrocution risk. Store fuel in approved containers away from the generator and any ignition sources.
Outdoor entertainment equipment — televisions, speakers, projectors — should come indoors or receive waterproof covers before storms arrive. Even weatherproof-rated equipment benefits from additional protection during severe weather events.
Pool and spa equipment requires special attention before storms. Turn off pool pumps, heaters, and lighting before lightning storms arrive. Lightning strikes near pools can energize water through connected equipment, creating extreme shock hazards for anyone in or near the water.
Landscape lighting fixtures generally withstand rain but benefit from pre-storm inspection. Tighten any loose fixtures, verify that stake-mounted lights remain firmly anchored, and confirm that all low-voltage wire connections remain above grade and protected from pooling water.
Creating an Emergency Electrical Response Plan
Every Spokane household benefits from an electrical emergency plan for severe storms:
Know your panel — Label every breaker clearly so any household member can identify and shut off specific circuits quickly. Practice locating and operating the main breaker disconnect so you can cut all power rapidly during an emergency.
Identify shut-off priorities — During lightning storms, shut off circuits powering outdoor equipment, pool systems, and sensitive electronics. This proactive step prevents surge damage even if whole-home protection fails.
Stock emergency supplies — Keep flashlights, batteries, and a battery-powered radio accessible. If power goes out, avoid using candles near water-damaged areas where gas leaks may have occurred.
Know when to call — Contact your utility company immediately if you observe downed power lines, transformer damage, or sparking equipment. Never approach fallen power lines or attempt to move them. Call a licensed electrician to inspect your property’s wiring after any significant storm event.
Post-Storm Electrical Inspection
After severe weather passes, conduct a follow-up inspection before resuming normal outdoor electrical use. Walk the property and look for storm damage — fallen branches on wiring, displaced fixtures, standing water near electrical equipment, and any burn marks or unusual odors at outlet locations.
Reset any tripped breakers one at a time, monitoring each circuit for immediate re-tripping that indicates a storm-caused fault. Do not repeatedly reset a breaker that continues to trip — this signals a wiring problem that requires professional diagnosis.
Test all GFCI devices again after the storm to confirm they still function properly. Storm surges can damage GFCI electronics even when the device appears physically intact.
Schedule a professional post-storm inspection with Evergreen Electric PNW if your property sustained any visible damage, experienced a direct lightning strike, or lost power for an extended period. Our electricians identify hidden damage that visual inspection cannot reveal.
