Deaf Smith County, TX

Overall riskRelatively Low
All 18 hazards for this countyrelative to other US counties, not a probability
Strong windRelatively High
  • Trim dead or overhanging branches before storm season.
  • Check that gutters, siding and roof edges are fastened tight.
  • Tie down or store outdoor furniture, grills and trampolines.
HailRelatively High
  • Photograph the roof and siding now, so you have a dated before picture.
  • Ask about impact-rated (UL 2218 Class 4) shingles when the roof is replaced.
  • Know your policy’s wind and hail deductible in dollars.
Winter weatherRelatively High
  • Clean gutters so melting snow drains instead of forming ice dams.
  • Check attic insulation and air sealing; warm attics cause ice dams.
  • Keep a snow shovel, ice melt and a backup heat plan.
DroughtRelatively High
  • Watch for new cracks in foundations, walls and door frames; drought shrinks clay soils.
  • Fix running toilets and dripping faucets.
  • If you have a well, know its depth and recent yield.
TornadoRelatively Moderate
  • Pick the safe room: lowest floor, interior, no windows. Tell everyone in the house.
  • Keep shoes, a flashlight and a helmet for each person there.
  • Turn on wireless emergency alerts on every phone.
Cold waveRelatively Moderate
  • Know where the main water shutoff is and that it turns.
  • Insulate pipes in unheated crawlspaces, garages and exterior walls.
  • Have the heating system checked before winter.
LightningRelatively Low
  • Use surge protection for electronics; ask an electrician about a whole-home surge protector.
  • Keep trees near the house healthy and trimmed.
  • Unplug sensitive electronics before a storm if you can.
WildfireRelatively Low
  • Clear dead leaves and needles from gutters, the roof and under decks.
  • Keep the first 5 feet around the house free of anything that burns (mulch, firewood, plants).
  • Cover vents with 1/8-inch metal mesh to keep embers out.
  • Look up your FEMA flood zone, and remember that "minimal hazard" zones still flood.
  • Raise or move valuables, the furnace and the water heater off a basement floor where you can.
  • Test the sump pump and its backup before the wet season.
Heat waveVery Low
  • Service the AC before the hot season and clear the outdoor unit of debris.
  • Change the AC filter; a clogged filter cuts cooling.
  • Plan a cool place to go if the power or AC fails.
Ice stormVery Low
  • Trim limbs that could fall on the house or the service drop.
  • Plan for a multi-day power outage: heat, water, phone charging.
  • If you own a generator, know how to run it outdoors safely.
EarthquakeVery Low
  • Strap the water heater to the wall with two straps.
  • Secure tall furniture and TVs to studs.
  • Know how to shut off gas at the meter, and only do it if you smell gas.
LandslideVery Low
  • Watch for new cracks in the ground, tilting trees or fences, and doors that stick.
  • Keep gutters and drains directing water away from slopes.
  • Know the signs of a debris flow during heavy rain.

November5 tasks

  1. This month
    Press the test button on every smoke and CO alarm.

    An alarm you have not heard in months may have a dead battery or sensor. NFPA recommends testing smoke alarms at least once a month.

    How

    Hold the test button until it sounds. Anything silent or chirping: replace the battery, or the whole alarm if it is past its date.

    MonthlyEvery homeNFPA: Smoke alarms
  2. This month
    Check the date on the back of every smoke and CO alarm.

    Smoke alarms wear out: NFPA advises replacing them 10 years after the manufacture date. CO alarms have their own end-of-life date printed on them.

    How

    Twist each alarm off its base and read the date. Replace any past its life; swap batteries in alarms that take them.

    YearlyEvery homeNFPA: Smoke alarms
  3. This month
    Look under every sink and around toilets and the water heater for drips.

    Slow leaks rot cabinets and subfloors long before they show. Catching one early is a washer, not a floor.

    How

    Use a flashlight: feel supply lines and the shutoff valves, look for stains, warped cabinet floors or a toilet that rocks.

    Every 3 monthsEvery home
  4. Watch
    Look in the attic with a flashlight after the first big storm of the season.

    Stains on the roof deck, wet insulation or daylight around vents show leaks early, and droppings show pests.

    How

    Stay on the joists. Look around chimneys, vent pipes and valleys, the places most leaks start.

    YearlyEvery home
  5. Watch
    Stock a power-outage kit: flashlights, batteries, water, a battery radio.

    Winter storms bring multi-day outages.

    How

    Keep it in one bin. Add a phone power bank and a list of medicines that need power or refrigeration.

  2. Watch
    Degrease the range-hood filter.

    Grease-clogged hood filters stop pulling smoke and grease out of the kitchen and can feed a stovetop fire.

    How

    Pop the metal filter out and soak it in hot water with dish soap and baking soda, or run it through the dishwasher if the maker allows.
