  • ...Next Storm Brings Strong Winds but Not Much Rain or Snow...
    The next in a series of storms is projected to impact the region
    Wednesday afternoon through Thursday, with a weaker system
    brushing across the region Friday morning. This storm has a good
    amount of wind energy with it, but is relatively warm and moderate
    at best in terms of precipitation potential. Here are the key
    points.
    * Timing: Strong south/southwest winds developing along the
    mountain ridges Wednesday, becoming strong in valley locations
    areawide by pre-dawn Thursday morning and lasting through the
    afternoon Thursday. Periods of light to moderate rain affecting
    the northern Sierra and northeast California Wednesday evening
    into Friday morning. Snow levels will generally remain above
    7500-8000 feet but may temporarily lower to near 7000 feet
    Wednesday night and again early Friday morning. Western Nevada
    and the eastern Sierra in Mono County are likely to see minimal
    precipitation.
    * Impacts: Strong winds Thursday may create travel problems in
    wind prone areas, strong turbulence for aviation, localized
    power outages and tree/fence damage, and impacts to any open ski
    areas. Rapid fire spread is possible in lower elevation grassy
    vegetation. Light snow accumulations could result in travel slow
    downs over Sierra passes, with the highest risks Thursday night
    into Friday morning.
    * Confidence: High confidence that we`ll see a storm Wednesday
    through Thursday. Medium but increasing confidence in wind
    intensity, precipitation amounts, and rain-snow line elevation.
    Some fluctuations in forecasts remain possible. Sierra passes
    above 7500 feet have the greatest risk of snow impacts.
    * What Can I Do Now? Plan for strong winds by securing outdoor
    objects, trash cans, canopies, and construction equipment by
    Wednesday afternoon. If you have travel plans around the region
    Thursday into Friday, anticipate some delays due to wind and/or
    light mountain snows. Double check your chains and winter
    travel supplies. There could be some delays for flights
    departing Reno or diversions of incoming flights Thursday
    morning if strong winds materialize.
    The upcoming weekend looks overall pretty decent with seasonable
    temperatures and light winds. Another low-moderate end storm
    remains possible late Sunday night through Monday evening. This
    storm is trending colder and has a greater risk of snow impacts
    for mountain roads Monday, along with another region-wide bout
    with strong winds.
