    • LATEST LOCAL FORECAST: Equivalent Tropical Storm force wind
      • Peak Wind Forecast: 30-40 mph with gusts to 55 mph
      • Window for Tropical Storm force winds: early Thursday
        morning until Thursday afternoon
    • THREAT TO LIFE AND PROPERTY THAT INCLUDES TYPICAL FORECAST
      UNCERTAINTY IN TRACK, SIZE AND INTENSITY: Potential for wind 39
      to 57 mph

      • The wind threat has remained nearly steady from the
        previous assessment.
      • PLAN: Plan for hazardous wind of equivalent tropical storm
        force.
      • PREPARE: Remaining efforts to protect property should be
        completed as soon as possible. Prepare for limited wind
        damage.
      • ACT: Move to safe shelter before the wind becomes hazardous.
    • POTENTIAL IMPACTS: Limited
      • Damage to porches, awnings, carports, sheds, and unanchored
        mobile homes. Unsecured lightweight objects blown about.
      • Many large tree limbs broken off. A few trees snapped or
        uprooted, but with greater numbers in places where trees
        are shallow rooted. Some fences and roadway signs blown
        over.
      • A few roads impassable from debris, particularly within
        urban or heavily wooded places. Hazardous driving
        conditions on bridges and other elevated roadways.
      • Scattered power and communications outages.
  • FLOODING RAIN
    • LATEST LOCAL FORECAST: Flash Flood Watch is in effect
      • Peak Rainfall Amounts: Additional 2-4 inches, with locally
        higher amounts
    • THREAT TO LIFE AND PROPERTY THAT INCLUDES TYPICAL FORECAST
      UNCERTAINTY IN TRACK, SIZE AND INTENSITY: Potential for
      moderate flooding rain

      • The flooding rain threat has remained nearly steady from
        the previous assessment.
      • PLAN: Emergency plans should include the potential for
        moderate flooding from heavy rain. Evacuations and rescues
        are possible.
      • PREPARE: Consider protective actions if you are in an area
        vulnerable to flooding.
      • ACT: Heed any flood watches and warnings. Failure to take
        action may result in serious injury or loss of life.
    • POTENTIAL IMPACTS: Significant
      • Moderate rainfall flooding may prompt several evacuations
        and rescues.
      • Rivers and tributaries may quickly become swollen with
        swifter currents and overspill their banks in a few places,
        especially in usually vulnerable spots. Small streams,
        creeks, canals, arroyos, and ditches overflow.
      • Flood waters can enter some structures or weaken
        foundations. Several places may experience expanded areas
        of rapid inundation at underpasses, low-lying spots, and
        poor drainage areas. Some streets and parking lots take on
        moving water as storm drains and retention ponds overflow.
        Driving conditions become hazardous. Some road and bridge
        closures.
  • TORNADO
    • LATEST LOCAL FORECAST:
      • Situation is unfavorable for tornadoes

        with gusty winds may still occur.
      • PREPARE: Little to no preparations needed to protect
        against tornadoes at this time. Keep informed of the latest
        tornado situation.
      • ACT: Listen for changes in the forecast.
    • POTENTIAL IMPACTS: Little to None
      • Little to no potential impacts from tornadoes.

Flash Flood Watch

National Weather Service Greenville-Spartanburg SC
232 PM EDT Wed Oct 28 2020

.Deep tropical moisture will spread over the region tonight as
Hurricane Zeta makes landfall over the central Gulf Coast. As Zeta
moves across the Deep South tonight, bands of heavy rainfall will
develop over the western Carolinas and northeast Georgia. Heavy
rainfall coverage will increase over the southern Appalachians
Thursday morning as the remnants of Zeta pass overhead. Flash
flooding will be possible where the heaviest accumulations occur
over the mountains, escarpment, and adjacent foothills. The heavy
rainfall and flash flood threat will quickly come to an end Thursday
afternoon as Zeta departs the region.

…FLASH FLOOD WATCH REMAINS IN EFFECT FROM MIDNIGHT EDT TONIGHT
THROUGH THURSDAY AFTERNOON…

The Flash Flood Watch continues for

  • Portions of northeast Georgia…western North Carolina and upstate
    South Carolina, including the following areas, in northeast
    Georgia, Habersham, Rabun and Stephens. In western North Carolina,
    Avery, Buncombe, Burke Mountains, Caldwell Mountains, Eastern
    McDowell, Graham, Greater Burke, Greater Caldwell, Haywood,
    Henderson, Macon, Madison, McDowell Mountains, Mitchell, Northern
    Jackson, Polk Mountains, Rutherford Mountains, Southern Jackson,
    Swain, Transylvania and Yancey. In upstate South Carolina,
    Greenville Mountains, Oconee Mountains and Pickens Mountains.

  • From Midnight EDT tonight through Thursday afternoon

  • Deep tropical moisture associated with Zeta will move into the
    region tonight. Heavy rainfall is expected to develop late tonight
    across the southern mountains and increase in coverage and
    intensity over the rest of the mountain and foothill region
    through Thursday morning as the remnants of Zeta move quickly
    across the southern Appalachians. Despite the fast storm motion,
    intense rain rates of 1-3″ per hour and total rainfall of 2-4
    inches, locally 5+ across favored ridgetops in the southern
    mountains through Thursday afternoon. Elevated soil moisture and
    streamflows ahead of Zeta only increases the likelihood of rapid
    stream rises and flash flooding due to heavy rainfall.

  • Rapid rises of area streams are likely with several streams
    possibly exceeding bankfull, resulting in areas of flash
    flooding. Expect primary impacts to occur to adjacent low-lying
    areas that typically flood, including farmland, parks, and
    low-water crossings. However, an isolated area or two of more
    significant flash flooding is possible. Excessive runoff may
    result in flooding of urban areas as well. Isolated debris flows
    or landslides are possible near steeper slopes that receive 4+
    inches of rain. A few mainstem rivers, especially the Little
    Tennessee, Tuckasegee, Pigeon, and upper French Broad, may also
    experience minor flooding during the day on Thursday and high
    river levels may persist into Friday morning.

PRECAUTIONARY/PREPAREDNESS ACTIONS…

A Flash Flood Watch means there is a potential for rapid onset
flooding based on current forecasts. Flash flooding is a very
dangerous situation and may impact areas that do not typically
flood. Please monitor the latest forecasts and be prepared to take
action quickly should Flash Flood Warnings be issued.

Rainfall of more than five inches in similar storms has been
associated with an increased risk of landslides and rockslides. If
you live on a mountainside or in a cove at the base of a mountain,
especially near a stream, be ready to leave in advance of the storm
or as quickly as possible should rising water, moving earth, or
rocks threaten. Consider postponing travel along mountain roads
during periods of heavy rainfall.
