...FLOOD ADVISORY IN EFFECT UNTIL 4 AM EDT TUESDAY...

* WHAT...Flooding caused by excessive rainfall is expected.

* WHERE...Central, southern, and eastern Gaston County, North
  Carolina

* WHEN...Until 400 AM EDT Tuesday.

* IMPACTS...Nuisance flooding of low-lying areas adjacent to streams
  and other poor-drainage areas, including farmland, parks,
  greenways, boat-access areas, golf courses, underpasses, and
  parking lots.  Isolated, shallow flows over roadways is possible.
  A few flood-prone, low-water crossings may become impassible.  A
  small culvert washout or two is possible.

* ADDITIONAL DETAILS...
  - At 958 PM EDT, Doppler radar and automated rain and
    streamgauges indicate that portions of Gaston County,
    primarily along a line from Bessemer City to Dallas, Stanley
    and Mount Holly, have seen between 2 and 3 inches of rainfall
    over the past 4-6 hours as a result of the outer rainbands of
    a weak coastal low pressure system.  Over the past two hours,
    more intense bands have been pivoting over southern and
    eastern Gaston County, including over the city of Gastonia,
    capable of producing rainfall rates of 1-1.5 inches per hour.
    These bands are pushing west toward Bessemer City and Kings
    Mountain with lighter rainfall entering Gaston County from
    the east.  Nevertheless, these bands have enhanced areas of
    excessive runoff and are increasing the rate of rise along
    area streams.  Several headwaters will be reaching and
    exceeding bankfull conditions within the next 15-60 minutes,
    resulting in nuisance flooding of adjacent low-lying areas.

    Areas of greatest concern include from Crowders to Gastonia
    to Belmont, Cramerton, and Mount Holly within flood-prone
    areas adjacent to streams and other common, flood-prone poor-
    drainage areas, roadways, and intersections.  The streamgauge
    along Catawba Creek at E Hudson Blvd indicates bankfull
    conditions are imminent and flooding of the Catawba Creek
    Greenway and adjacent low-lying, flood-prone areas will occur
    within the next 15-30 minutes.  Floodwaters may reach 1-3
    feet deep along the greenway and within the floodplain as the
    stream rises to near 10 feet over the next 1-2 hours.

  - Soils are saturated and streams are swollen.  Therefore,
    additional heavy rain may quickly create new areas of
    flooding and cause previous areas of flooding to redevelop.
    As a result, a Flash Flood Warning may be issued later
    tonight if conditions continue to deteriorate.  Caution is
    advised near any stream or other vulnerable area.  Seek
    higher ground immediately if heavy rain develops and streams
    rise quickly.  Please have a plan in place should flash
    flooding develop and do not hesitate to act.

  - Some locations that may experience nuisance flooding
    include...
    Gastonia, Huntersville, Kings Mountain, Mt Holly, Belmont,
    Bessemer City, South Gastonia, Dallas, Stanley, Cramerton,
    Lowell, Ranlo, Mcadenville, Crowders Mountain State Park,
    Kings Mountain State Park, Crowders and Lucia.

PRECAUTIONARY/PREPAREDNESS ACTIONS...

Keep children away from storm drains, culverts, creeks and streams.
Water levels can rise rapidly and sweep children away.

Be especially cautious at night when it is harder to recognize the
dangers of flooding.

Be aware of your surroundings and do not drive on flooded roads.
