    SACRAMENTO, Calif. —

    A warmer weather system will bring widespread rain back to Northern California on Tuesday, which will likely lead to snow at lower elevations melting.

    Existing snow combined with rain could lead to localized street flooding on the west slope, making Tuesday a KCRA 3 weather Impact Day.

    Impact Days are issued when weather conditions could be a nuisance for travel or outdoor activities.

    This system will tap into moisture from a weakening atmospheric river with roots in the tropics. Because of this warmer setup, the snow level will stay well above the Tahoe area passes.

    Flooding in communities that have seen several feet of snow is possible as warm rain is expected to melt snow and lead to poor drainage flooding. Rain will also add significant weight to piles of snow on rooftops.

    The Sierra Avalanche Center warned that there is a high avalanche danger on Tuesday. The incoming rain will add a lot of weight to the upper layers of the snowpack, making it even more unstable.

    “Blowing and drifting snow has led to unstable wind slabs in areas that have filled in with drifted snow,” the center said. “Weak layers deep in the snowpack remain unstable in some areas. Consider avoiding avalanche terrain in areas where wind slabs exist, near any areas where you have triggered any snowpack collapses or audible whumpfing, or where recent avalanches have occurred.”

    Below is a breakdown of what the KCRA 3 weather team is expecting:

    Rain

    Scattered showers arrive late Monday night into early Tuesday morning.

    Rainfall will turn steady as the busiest part of the morning commute is starting in the Valley, Foothills and Sierra. Showers will continue on and off throughout the day and into the overnight hours before tapering off quickly Wednesday morning.

    The heaviest rain is forecast in higher terrain and areas along and north of Interstate 80.

  • Northern California wind advisory issued for gusts up to 45 mph

    Northern California wind advisory issued for gusts up to 45 mph

    [ad_1]

    (FOX40.COM) — A wind advisory for the Sacramento Valley will soon go into effect for gusts that may reach up to 45 mph over the next few days.

    The wind advisory begins at 11 p.m. on Tuesday and is expected to end at 8 a.m. on Thursday. North winds are forecast to be 20-30 mph with gusts reaching up to 45 mph. Areas affected are the South Sacramento Valley, Central Sacramento Valley, and Delta regions. Areas along Interstate 5 and portions of Interstate 80 and 505 will also be impacted.

    “Wednesday will be warmer but it’s windier – not a fun day to be outside because of those gusts,” said FOX40’s chief meteorologist Adam Epstein.

    The strongest winds are forecast to be on Tuesday night and going into Wednesday morning with gusts strong enough to cause power outages or blow down tree limbs. The winds can also make driving more difficult for drivers so officials advise commuters to travel with caution.
