Storm season in South Louisiana is not a hypothetical — it’s an annual certainty. From late May through November, Houma, Thibodaux, Morgan City, and surrounding communities face a recurring cycle of heavy rain, high winds, and the kind of extended power outages that make life genuinely dangerous, not just inconvenient.
Most homeowners think about storm prep in terms of plywood and flashlights. The smarter play is to start with your electrical system. A failing breaker, an unprotected panel, or a generator that hasn’t run since last October can cost you far more than a storm ever will. This guide walks through what actually needs to happen before the next system rolls in.
Why Your Electrical System Is Your First Line of Defense
When a major storm hits, your utility grid goes down — sometimes for days, sometimes for weeks. At that point, everything that keeps your household functional — refrigeration, medical equipment, air conditioning in Louisiana summer heat, well pumps, security systems — depends entirely on what you’ve prepared ahead of time.
The electrical system is also one of the most common sources of post-storm damage claims. Surge events from lightning strikes and grid restoration can destroy appliances, fry circuit boards, and start fires in walls. Corroded or overloaded breakers that were limping along fine in normal conditions give out entirely under storm stress.
Preparation isn’t complicated, but it does require doing the right things in the right order before the forecast turns red.
Step 1: Service Your Standby Generator Before Season Starts
If you have a whole home standby generator, late spring is the time to schedule its annual maintenance — not mid-August when every licensed technician in the parish is already booked two weeks out.
A proper pre-season service covers:
- Oil and filter change — most manufacturers recommend this annually or every 50-200 hours of runtime, depending on the unit
- Spark plug inspection and replacement if needed
- Air filter check
- Battery test — a weak starter battery is one of the most common reasons generators fail to start automatically during an outage
- Transfer switch test — verifying that the unit starts, transfers load cleanly, and shuts down properly
- Fuel system inspection — checking for leaks, stale fuel in the lines, and proper propane or natural gas supply pressure
- Coolant level check on liquid-cooled units
For Generac standby generators specifically, the dealer-level diagnostic can also pull fault codes stored in the controller that aren’t visible to the homeowner — issues that could cause a no-start at the worst possible moment.
Shockwave Generators & Electric has been servicing whole home generators across South Louisiana since 2013 as a Generac Authorized Dealer. That authorization means factory-trained technicians, genuine OEM parts, and warranty-compliant service records.
If you don’t yet have a standby generator, the period before storm season is the smartest time to install one. Lead times on equipment and installation crews get long fast once the first named storm appears on a forecast map.
Step 2: Check Your Breakers and Electrical Panel
Most homeowners never think about their breaker panel until something trips. But breakers are mechanical devices with a finite lifespan, and South Louisiana’s heat and humidity accelerate the wear on electrical components more than most climates.
Signs your panel needs attention before storm season:
- Breakers that trip frequently or won’t reset cleanly — this isn’t a normal quirk, it’s a warning
- A panel that’s more than 20 years old — older panels may use breaker types that are no longer code-compliant or are known to fail
- Warm or hot panel cover — heat from a panel face is a red flag
- Burn marks, rust, or visible corrosion on any component inside the panel
- Breakers that feel loose or that you have to hold to keep reset — these should be replaced immediately
Storm conditions put unusual loads on breakers. When power is restored after an outage, the inrush current from multiple appliances coming back online simultaneously is significant. Breakers that are already compromised can fail under that load — or worse, allow a fault condition to pass unchecked.
Breaker replacements are one of the most common pre-season services Shockwave performs across the Houma area. It’s straightforward work that prevents failures in high-stakes situations.
If your panel is older, undersized for your home’s current load, or from a manufacturer with documented reliability issues, a panel evaluation is worth scheduling now — not after a storm reveals the problem the hard way.
Step 3: Install Whole Home Surge Protection
A direct lightning strike is the obvious surge threat, but most surge damage comes from something far more common: grid restoration. When utility crews restore power to a neighborhood after an outage, the voltage that comes back through the line isn’t always clean. Fluctuations and transient spikes in those first moments can quietly degrade or outright destroy electronics throughout your home.
Individual power strip surge protectors offer limited protection — they address only what’s plugged into them, and they’re not rated for the kind of energy a grid-level surge event delivers.
Whole home surge protection installs at the electrical panel and intercepts excess voltage before it reaches any circuit in the house. It protects everything: your HVAC system, refrigerator, washer, dryer, EV charger, smart devices, and any medical equipment. One device, installed once, covering the entire home.
Shockwave currently includes whole home surge protection at no additional charge with every generator purchase — a combination that addresses both sides of the storm power problem.
Step 4: Schedule a Pre-Season Safety Inspection
If it’s been more than a year since a licensed electrician looked at your home’s electrical system, a pre-season safety inspection is a low-cost way to catch problems before they become emergencies.
A thorough inspection covers:
- Panel condition and breaker integrity
- Grounding and bonding
- Smoke and CO detector function
- GFCI and AFCI protection in required locations
- Outdoor outlet and lighting weatherproofing
- Any visible wiring concerns in attic, crawlspace, or garage
Louisiana’s climate means outdoor electrical components — meter pans, weatherheads, exterior outlets, security and flood lighting — take more environmental punishment than in drier regions. These are worth a close look before every storm season.
What to Do Immediately After a Storm
Even well-prepared homes can sustain storm damage. Here’s what matters most in the 24–48 hours after a storm event:
Do not enter standing water near your electrical panel, outlets, or any energized equipment. Water and live circuits are a fatal combination. If your home flooded and you’re unsure whether power is safe, call a licensed electrician before you restore anything.
Do not run a portable generator indoors or in a garage. Carbon monoxide poisoning kills people every storm season in this region. Portable generators belong outside, away from windows and doors, period.
Inspect your standby generator after extended runtime. Check oil level, look for any unusual sounds or exhaust smoke, and verify that coolant levels are normal on liquid-cooled units. Extended runtime in summer heat puts more demand on these systems than occasional testing does.
Watch for signs of surge damage in the days after power is restored — appliances behaving erratically, smart devices that won’t reconnect, or HVAC systems that run but don’t cool properly. These can be symptoms of quiet surge damage that occurred during grid restoration.
Don’t Wait for the Forecast to Turn
The worst time to think about storm season prep is when a named storm is already in the Gulf. Technician availability drops, equipment lead times spike, and the margin for anything to go wrong during installation shrinks to zero.
The right time is now — when the calendar says storm season is open, the schedule is still clear, and the work can be done without pressure.
