  • ...The 2018 Spring Flood Potential Outlook for East Tennessee...
    Southwest Virginia...and Extreme Southwest North Carolina...
    ...Flood Risk Is Above Average For The Forecast Area...
    Introduction...
    This is the 2018 Spring Flood Potential Outlook issued by the
    National Weather Service in Morristown, Tennessee for east
    Tennessee, southwest Virginia, and extreme southwestern North
    Carolina. This issuance outlines current river and soil moisture
    conditions and highlights potential situations that would induce
    flooding or exacerbate drought.
    In summary, the 2018 Spring Flood Potential is ABOVE AVERAGE.
    The following sections describe past and current conditions and
    future expectations.
    Snow pack...
    Snow pack is nearly absent thanks to a warm February.
    Precipitation...
    Over the past 30 days, thanks to a wet February, precipitation has
    generally ranged from near normal across the eastern mountains,
    southeast Tennessee, and southwest North Carolina, to over 200%
    of normal across the northern Cumberland Plateau and much of
    southwestern Virginia.
    Over the past 60 days, precipitation ranged generally from 65 to 85
    percent of normal across the eastern mountains as well as the
    southern tier of counties from southeast Tennessee to southwest
    North Carolina, to 125 to 150 percent of normal across the northern
    Cumberland Plateau and much of southwestern Virginia.
    Beyond 60 days, December precipitation was generally below normal
    across most of the area.
    Temperatures...
    December temperatures averaged only 1 degree below normal. January
    was a little cooler, running 3 to 4 degrees below normal. February
    brought a few days of record warmth, and the month as a whole
    averaged 8 to 10 degrees above normal.
    Drought...
    While abnormally dry conditions continue to be displayed by the
    Drought Monitor this week in the counties surrounding Chattanooga,
    heavy rainfall this week will likely bring about the end of those
    lingering climatologically dry conditions.
    Soil Moisture...
    February rains have brought soil moisture conditions back to near
    seasonal normals. Rainfall this week will temporarily bring surface
    soils to saturation.
    Streamflows...
    Streamflows were near to much above normal thanks to plentiful
    rainfall during February and in recent days. The locations listed
    below are not expected to flood during the current rain event.
    However, a few rivers in extreme southeastern Tennessee are expected
    to experience minor flooding today.
    Streamflows as a percent of daily normal are given for river points
    in, or immediately upstream from, our hydrologic service area:
    River... Location... 2/28/18
    N Fork Holston River Saltville VA 89%
    Clinch River Cleveland VA 145%
    Clinch River Tazewell TN 176%
    Powell River Arthur TN 255%
    Emory River Oakdale TN 249%
    Pigeon River Hepco NC 91%
    French Broad River Asheville NC 106%
    Tennessee River Basin Reservoir Levels...
    Due to recent heavy rain and flood events, the percent of available
    flood control storage for reservoirs in the Tennessee Basin above
    Chattanooga is down to 84 percent.
    Meteorological Outlook...
    The Week Two Outlook for days 8 to 14 shows an expectation of below
    normal temperatures...and near normal precipitation.
    The Climate Outlook for the month of March shows no discernible
    trends on the temperature forecast, meaning there are equal chances
    for below...near...or above normal temperatures. But there is a
    slightly elevated expectation for above normal precipitation.
    The longer term Climate Outlook for the 3 month period of March
    through May indicates slightly elevated expectations for above
    normal temperatures and above normal precipitation.
    The 2018 Spring Flood Outlook...
    Based on all of the above considerations...an ABOVE AVERAGE flood
    potential is expected for the East Tennessee, Southwest Virginia,
    and extreme Southwest North Carolina basins.
