A Montana snowstorm can turn a routine propane delivery into a difficult trip down an unplowed driveway – right when your furnace is working its hardest. To prepare propane tanks for snowstorms, focus on two things before the forecast turns serious: maintain enough fuel for higher winter use and keep the tank, regulator, and delivery route safely accessible.
A little preparation protects more than indoor comfort. Propane may heat your home, water, appliances, garage, shop, or backup generator. For seasonal homes and commercial properties, a storm can also make it harder to check the tank in person. Planning ahead gives your family or operation more room to handle changing weather without worrying about a preventable runout.
Check Your Propane Level Before the Storm
Cold weather increases propane use because your heating system must run longer to maintain the same indoor temperature. Wind, drifting snow, and below-zero temperatures can push usage higher than expected, especially in older homes, homes with long driveways, and properties that heat more than one building.
As a practical rule, do not wait until the tank is nearly empty to request service. If you are a will-call customer, check the gauge regularly during winter and contact your provider well before the tank reaches a low level. Many homeowners use 30 percent as a good point to make the call, but the right timing depends on tank size, household usage, forecasted temperatures, and how far a delivery truck must travel to reach you.
Remember that the percentage on a propane tank gauge is not the same as the amount of usable fuel in a gasoline tank. Propane tanks are filled only to about 80 percent to leave room for the liquid to expand. A reading of 20 percent on a 500-gallon tank is very different from 20 percent on a smaller tank. If you are unsure how much fuel remains or how quickly you use it, ask your propane provider to help you interpret your gauge and delivery history.
Automatic delivery can take much of this guesswork off your plate. Degree-day tracking estimates fuel use based on outdoor temperatures, while wireless tank monitoring provides real-time tank-level information. These systems are especially helpful when a storm arrives quickly or when you manage a second home, rental property, ranch, or business site from a distance.
Keep the Tank and Regulator Clear of Snow
Snow around a propane tank is normal. A tank is designed to stay outdoors, and it does not need a blanket, tarp, or homemade enclosure to stay warm. In fact, covering the tank or regulator can create a safety issue by trapping moisture, blocking ventilation, or making equipment harder to inspect.
What does need attention is access to the tank valve, gauge, and regulator. The regulator is the small component that reduces pressure from the tank before propane enters your home. Heavy snow, drifting snow, or ice buildup can interfere with its vent. Keep the regulator and its vent clear so it can operate properly.
Use a soft broom or brush to gently remove loose snow. Avoid striking the regulator, valve, piping, or tank with a shovel, ice chopper, snowblower, or metal tool. Do not pour hot water on frozen equipment. Sudden temperature changes can refreeze into ice, and forceful attempts to remove ice can damage critical parts.
If the regulator is heavily iced over, you see damaged piping, or you cannot safely clear the area, call for trained service rather than trying to repair it yourself. Never use an open flame, space heater, torch, or heat gun near propane equipment.
Do Not Stack Snow Against the Tank
When plowing or shoveling, direct snow away from the tank and from the path a delivery driver needs to use. Large snowbanks can hide the tank, block the fill connection, damage piping, and make emergency access difficult. Marking the tank location with a tall, visible driveway marker before winter can be helpful where drifting snow is common.
Also keep the area around the tank free of stored firewood, trash bins, vehicles, and other obstacles. A clear working area helps a driver complete a delivery safely and lets service personnel reach the equipment if you need assistance during bad weather.
Make Delivery Access Part of Your Storm Plan
A full tank does not help much if a delivery truck cannot safely reach it before your supply becomes critical. Before a snowstorm, clear your driveway and the route to the tank as early as possible. Pay special attention to steep grades, tight turns, gates, low branches, and icy areas where a large truck may lose traction.
If a gate is normally locked, make sure the delivery arrangement is clear. Keep pets secured on delivery day, and ensure your house number is visible from the road. These small details save time when a driver is working through snow, reduced visibility, and a full delivery schedule.
For properties with shared lanes or private roads, coordinate with neighbors or road-maintenance services ahead of time. It may be worth confirming who plows which section of the road and when. A road that is passable for a pickup may not be safe for a propane bobtail truck.
If conditions become too hazardous for a delivery, that decision protects everyone involved. Calling early, rather than when the gauge is low, gives your supplier more options to schedule delivery around weather and road conditions.
Protect Your Home if Power Goes Out
A propane furnace, boiler, or heater often needs electricity for ignition, controls, fans, or circulation pumps. That means a propane tank can have plenty of fuel while your heating system still cannot operate during an outage. Know whether your home has a safe backup-power plan for essential heating equipment.
If you use a propane generator, include its fuel needs in your winter planning. Generator run time can draw down a tank faster than normal household use, particularly during a multi-day outage. Tell your propane provider about generator use so they can better understand your expected demand.
Portable propane heaters and cooking appliances require special care. Only use equipment rated for indoor use indoors, follow the manufacturer instructions, maintain required clearances, and ensure carbon monoxide alarms are working. Never bring an outdoor grill, patio heater, or camp stove into a garage, home, cabin, or enclosed porch. These appliances can create deadly carbon monoxide hazards.
Know the Signs That Require Immediate Action
Propane has a strong odor added to help people recognize a leak. If you smell propane, hear a hissing sound near the tank, see damaged equipment, or suspect a leak, leave the area immediately. Avoid flames, sparks, electrical switches, vehicles, phones, and anything that could ignite gas near the suspected leak.
Once you are safely away from the area, call 911 or your fire department if there is an immediate danger, then contact your propane supplier from a safe location. Do not return to the property or attempt to turn equipment back on until qualified professionals say it is safe.
It is also wise to test carbon monoxide alarms before winter weather arrives and replace batteries as needed. Carbon monoxide has no smell or color, and working alarms provide an essential warning if a fuel-burning appliance is not venting properly.
A Better Winter Routine for Propane Customers
The most reliable approach is not a last-minute storm checklist. It is a simple winter routine: watch your tank level, clear snow after each accumulation, keep the delivery route open, and communicate early if your usage or property access changes. If you leave town, arrange for someone to check the property or use monitored delivery service that can alert your provider to falling fuel levels.
For customers across southwest and central Montana, Big Sky Propane combines automatic delivery, degree-day tracking, and wireless monitoring with its Guaranteed No Runouts promise for monitored customers. That kind of planning is designed for the days when winter weather is least forgiving.
Before the next storm arrives, step outside while conditions are still manageable. A clear regulator, an open driveway, and a comfortable propane reserve can make a hard-weather week feel far more routine.
