Special Weather Statement issued February 11 at 10:13AM PST by NWS Reno NVAlert
Prepare Ahead of the Storm: Utilize the next 48 hours wisely
- Existing Snow: Do as much cleanup from weekend storm as
possible. Reduce snow load on structures. Clear snow from drains
- Evaluate your "back up plans" for travel over the Sierra
(snow/rain) and wind prone valleys (wind) Wednesday-Thursday.
- Winds Incoming: secure loose objects, construction equipment,
and garbage cans ahead of the strong winds.
For the Mountain Communities and the Sierra (above 6000 feet)
- Plan for major delays in mountain travel midweek. High
confidence for travel impacts from heavy rains and/or heavy snow
for Wednesday and Thursday.
- MORE SNOW: Areas above 8500 feet should plan for a major
snowstorm, with areas of low visibility and increasing concerns
with snow loading on buildings.
- HEAVY RAIN or HEAVY WET SNOW? Areas below 8500 feet, the snow
level forecast is highly uncertain with scenarios ranging from
heavy rain to heavy wet snow. Plan for both and be sure to clear
any and all drainage areas of snow. Have a plan in place to mitigate
urban flooding concerns due to heavy rains.
- Strong winds are a safe bet for all areas in the mountains.
Primary travel impacts due to winds will range from issues for
high profile vehicles, rough air travel for flying, and impacts
to the higher elevation ski areas.
For the Foothills and Valleys (6000 feet and below):
- HEAVY RAIN or HEAVY WET SNOW? Snow level forecasts have been
widely varied with this storm, but a heavy rain scenario is
fairly certain. Rises on streams and terminal lakes are
possible. Poor drainage flooding is also likely for areas that
typically experience urban flooding during heavy rains,
especially areas where snow is damming up drains and culverts.
- Strong winds will result in high profile vehicle restrictions as
well as rough conditions for air travel. Damage to trees and
power lines is also possible along with minor structural damage.
Area lakes will also be contending with choppy conditions and
significant wave heights. See the High Wind Watch for more
