Preparing Your Marin Home’s Electrical System for Winter Storms
Marin winters bring wind, rain, and outages — and power surges when the lights come back on. A little electrical prep before the storms keeps your home safe and running.

Quick Answer
Preparing your Marin home’s electrical for winter storms means being ready for outages and the surges that follow. Add whole-home surge protection, plan backup power for essentials, keep flashlights and a charged power bank ready, know how to safely shut off power, and never touch downed lines. A pre-season electrical check catches weak spots.
Marin winters mean wind-driven storms, saturated ground, and power that comes and goes — and the return of power can be as hard on your electronics as the outage itself. A bit of readiness through our home electrical services goes a long way. Here’s how to prepare your home’s electrical for storm season.
Outage ReadinessBefore the Lights Go Out
Good power outage prep is mostly about not being caught off guard. Keep flashlights and a charged power bank accessible — not buried in a drawer — know where your electrical panel and main disconnect are, and make sure the path to them is clear. If anyone in the home relies on powered medical equipment, have a plan before the storm, not during it. Knowing how to safely shut off power to your home is a basic skill worth having down cold.
Surge ProtectionWhen Power Returns
The dangerous moment is often when power comes back. Storms and grid switching can send voltage spikes through the lines, and a surge can quietly damage electronics, appliances, and even your HVAC. Surge protection is the defense — and while power strips protect individual devices, whole-home surge protection installed at the panel guards everything at once. It’s an inexpensive upgrade relative to what it protects, and we cover it in our whole-home surge protection guide.
Why the surge matters as much as the outage — an outage is an inconvenience; a surge is damage. The moment power is restored after a storm is exactly when unprotected electronics get fried — which is why surge protection is a storm-prep item, not an afterthought.
Backup PowerKeeping Essentials Running
If storm outages are long or frequent where you live, backup power keeps the essentials going — refrigeration, heat, internet, a well pump. Options range from a portable generator with a transfer switch to a standby generator or a battery, and the right one depends on your outage exposure and must-run list, as we lay out in PSPS-season prep and our generator comparison. Storm season is the reason many Marin homeowners finally sort this out.
Safety FirstDuring and After a Storm
Storm electrical safety comes down to a few firm rules: never touch or approach a downed power line — assume it’s live and call the utility and 911; keep away from wet electrical equipment; and if your home floods, don’t restore power to affected areas until an electrician has checked them. The federal Ready.gov program, the Electrical Safety Foundation International, and PG&E all publish storm and outage safety guidance worth reviewing before the season.
Step by StepHow to Prepare for Winter Storms
Ready your outage kit
Keep flashlights and a charged power bank accessible, and know where your panel and main disconnect are.
Add whole-home surge protection
Install panel-level surge protection so the post-storm voltage spike doesn’t fry your electronics.
Plan backup power for essentials
Decide how you’ll keep refrigeration, heat, and internet running if outages are long or frequent.
Learn to shut off power safely
Know how to cut power at the main — and never touch wet or damaged electrical equipment.
Get a pre-season electrical check
Have an electrician catch weak connections, an aging panel, or missing protection before storms hit.
Key Takeaways
- Winter storm prep is about both the outage and the surge when power returns.
- Whole-home surge protection at the panel guards everything against post-storm spikes.
- Match backup power to your outage exposure and must-run essentials.
- Never approach downed lines, and don’t re-energize flooded areas until an electrician checks them.

The Bottom Line
Winter storm prep is two things: readiness for the outage and protection from the surge that follows. Ready an outage kit, add whole-home surge protection, plan backup power for your essentials, and know how to cut power safely. A pre-season electrical check ties it together — far better to find a weak spot in October than during the first big storm.
Frequently Asked Questions
How do I protect my electronics from post-storm power surges?
The strongest defense is whole-home surge protection installed at your electrical panel, which clamps down voltage spikes before they reach anything in the house — including hardwired equipment like HVAC that a plug-in strip can’t protect. Point-of-use surge strips add a second layer for sensitive electronics. Storms and the grid switching that follows an outage are exactly when damaging spikes occur, so surge protection is genuinely a storm-prep item. It’s inexpensive relative to the appliances and electronics it protects, and an electrician can add panel-level protection quickly.
Should I unplug things during a storm?
It’s a reasonable low-tech precaution for sensitive, expensive electronics if you’re home and a storm is active — unplugging fully removes them from any surge risk. But it’s not practical for everything, and it does nothing for hardwired equipment. That’s why installed surge protection is the better long-term answer: it protects the whole home automatically, whether or not you’re there to pull plugs. Unplugging a few key devices during an active storm and relying on surge protection for everything else is a sensible combination.
What backup power do I need for winter storms?
It depends on how long and how often your area loses power and what you can’t do without. For occasional short outages, a portable generator with a properly installed transfer switch covers essentials like refrigeration, some lights, and internet. For frequent or long outages, or if you have a well pump or medical equipment, a standby generator or battery may be worth it. The right choice comes down to your outage exposure and must-run list — the same framework as planning for PSPS season.
What should I do if a power line comes down near my home?
Treat every downed line as live and deadly, even if it looks harmless. Stay far away — don’t touch it, don’t touch anything it’s contacting, and keep others and pets back — and call 911 and the utility immediately. Downed lines can energize the ground and nearby objects like fences and puddles. If a line falls on your car while you’re in it, stay inside unless there’s fire, and call for help. This is the one storm hazard where the rule is absolute: never approach it.
Is it safe to use power after my home floods?
No — not until a licensed electrician has inspected the affected areas. Water and electricity are a dangerous combination, and flooding can damage outlets, wiring, and panel components in ways that aren’t visible but can cause shock or fire once power is restored. Don’t re-energize flooded circuits yourself. If you can safely reach the main disconnect with dry hands and footing, cutting power is wise; otherwise stay clear and call for help. Have the electrical checked before anything water-damaged is powered again.
Should I get an electrical check before storm season?
It’s a smart, low-cost habit, especially for older Marin homes. A pre-season check catches the weak points that storms expose — loose or corroded connections, an aging or overloaded panel, missing surge protection, and outdoor equipment that isn’t weathertight. Finding and fixing those in the dry months is far better than discovering them when the first big storm knocks out power or a surge damages your electronics. Think of it like servicing a roof before winter: cheap insurance against a much bigger, worse-timed problem.
