Weather Alert Detail

  • Special Weather Statement for South Willamette Valley County, Oregon
  • Special Weather Statement issued December 15 at 3:36AM PST by NWS
  • Effective: Thursday, December 14, 2017 at 12:55 p.m.
  • Expires: Friday, December 15, 2017 at 11 a.m.
  • ...PATCHY LIGHT FREEZING RAIN POSSIBLE THIS MORNING...
    A front offshore will push increasing rain into the region later
    this morning. At 3 am, temperatures in many lowland areas were in
    the upper 20s to lower 30s. Temperatures will rise this morning.
    But, there is a chance that temperatures may not warm above
    freezing before the rain begins. This would result in patchy
    light freezing rain. Since rainfall will be light, little if any
    ice accumulation is expected.
    Threat of the freezing rain will be 5 am and 8 am for valleys in
    the Coast Range and Willapa Hills, and from 8 to 10 am for the
    Willamette Valley and Clark County.
    Again, most areas will not see the freezing rain, as will be
    quite patchy and short-lived.
    Threat of patchy freezing rain may last until 1 pm for valleys in
    the south Washington Cascades, far north Oregon Cascades and Upper
    Hood River Valley.
    Motorist driving about this morning should be prepared for locally
    icy conditions.

  • Special Weather Statement issued September 16 at 3:01PM PDT by NWS

  • Expires: Sunday, September 17, 2017 at 1:15 p.m.
  • ...A CHANGE TO COOL AND WET WEATHER BEGINNING SUNDAY...
    A developing low pressure system in the Gulf of Alaska will
    settle over the Pacific Northwest this week. Expect much cooler
    temperatures and several rounds of rain and snow in the high
    Cascades. Rain will begin Sunday afternoon and continue at times
    through much of the week. Snow levels will drop to 5000 to 6000
    feet by Monday and remain near that level through the remainder of
    the week.
    The series of weather system through the first half of the week
    will bring increasing prospects for seeing substantial rainfall.
    While this will be favorable for suppressing the regions
    wildfires, it will also increase the chances for seeing flash
    flooding and debris flows in and below the burn scars. Rainfall
    potential increases each day early this week, likely culminating
    with the potential for some heavy rainfall Tuesday night into
    Wednesday when the risk of flash flooding is greatest in the areas
    with burn scars.
    People planning travel or outdoor activities, especially in the
    mountains should be prepared for the changing conditions.
