Heavy Rains and Thunderstorms Expected Today and Friday
Outlook
A cold front will cross our area from the west today bringing a line of very heavy showers and a few storms. This cold front will stall to our south on Saturday, bringing temporarily dry weather, but another system will bring additional moisture to the region Sunday. The stalled front will retreat north as a warm front Monday as another strong cold front slides east. This cold front will slowly move into our area and may stall, keeping our region unsettled through much of next week.

Weather Hazards

Flood Advisory
National Weather Service Greenville-Spartanburg SC
310 AM EST FRI DEC 28 2018
The National Weather Service in Greenville-Spartanburg has issued a
* Flood Advisory for...
Macon County in western North Carolina...
* Until 700 AM EST.
* At 305 AM EST, Doppler radar indicated a broad area of heavy rainfall moving northward across Macon County. Radar and rain gauges indicated rainfall rates of one-half to one inch per hour in the heaviest downpours, and this heavy rain was affecting locations that have already received 1.5 to 3 inches of rain in the past 12 hours. Flooding of streams and creeks will likely develop through the early morning hours.
* Some locations that will experience flooding include...
Franklin, Highlands, Nantahala Lake, Ellijay, Burningtown, Kyle, Otto, Rainbow Springs, Wayah Bald and Cowee. Flooding is most likely along Sugar Cove Creek near the Swain County border, Caler Fork east of Cowee, and the Little Tennessee River around Franklin and associated tributaries.
PRECAUTIONARY/PREPAREDNESS ACTIONS...
Turn around, don`t drown when encountering flooded roads. Most flood deaths occur in vehicles. Be especially cautious at night when it is harder to recognize the dangers of flooding.
The additional heavy rain will increase the risk of landslides, especially in areas where slides have occurred in the past. Be especially alert if you are near a stream, especially at the base of a mountain or in a cove. Watch for loose-moving soil and rocks or a sudden increase in streamflow. Leave the area quickly if this is observed. When driving along roads where the terrain is steep or rocky, watch and listen for falling rocks, mud, trees and other debris.
Only when it is safe to do so, please report floodwaters or landslides flowing over roads or threatening property to the National Weather Service by calling toll-free, 1, 800, 2 6 7, 8 1 0 1, by posting on our Facebook page, or via Twitter using hashtag NWSGSP. Your message should describe the event and the specific location where it occurred, including roadways, nearby cross streets, stream names, and other landmarks.
Flood Watch
National Weather Service Greenville-Spartanburg SC
1009 PM EST Thu Dec 27 2018
...HEAVY RAIN MAY PRODUCE FLOODING THROUGH FRIDAY NIGHT...
.Abundant moisture from the Gulf of Mexico will stream across the western Carolinas and northeast Georgia through Friday ahead of a cold front moving slowly eastward. The rain may be heavy at times. Soils remain nearly saturated from recent snowmelt and rainfall, and many area streams and reservoirs are already running at high levels. This poses an increased risk of flooding as rainfall redevelops over the region. Showers, with a few embedded thunderstorms, will arrive with the cold front on Friday and the associated higher rainfall rates could cause flooding problems to quickly worsen.
...FLOOD WATCH REMAINS IN EFFECT THROUGH SATURDAY MORNING...
The Flood Watch continues through Saturday morning
* Periods of moderate to heavy rainfall, through Friday will combine with wet conditions and already high stream levels, to produce excessive water runoff in many areas. Rainfall totals of 1 to 3 inches are likely across the region, with locally higher amounts in the extreme southern Appalachians.
* Several streams will likely leave their banks and flood adjacent low-lying areas and water crossings. This is especially true near south-facing mountain ridges such as the Blue Ridge Escarpment, but flooding may occur just about anywhere in the western Carolinas and northeast Georgia. In urban areas, street flooding is possible, impeding travel. Additionally, lakes are likely to remain at high levels heading into the weekend and minor shoreline flooding is possible.
* River flooding is most likely along the upper reaches of the French Broad River in Transylvania and Henderson counties. Additional isolated flooding may develop east of the mountains on Friday as heavier showers and embedded thunderstorms cross the region along and ahead of a cold front.
PRECAUTIONARY/PREPAREDNESS ACTIONS...
A Flood Watch means there is a potential for flooding based on current rainfall forecasts.
You should monitor later forecasts and be alert for possible Flood Warnings and Flood Advisories. Those living in areas prone to flooding should be prepared to take action. These actions typically include moving to higher ground if flooding is imminent, and moving belongings to higher ground well before flooding develops in normally flood-prone areas.
Wind Advisory
URGENT - WEATHER MESSAGE
National Weather Service Greenville-Spartanburg SC
1003 PM EST Thu Dec 27 2018
...VERY WINDY CONDITIONS EXPECTED THROUGH FRIDAY MORNING ACROSS THE EXTREME SOUTHERN APPALACHIANS...
.Between intense low pressure in the middle of the country and a ridge of high pressure over the East Coast, strong winds will continue to develop and affect the higher elevations of the southern Appalachians. Occasionally heavier rain showers could transport wind energy down into the lower mountain valleys at times as well.
...WIND ADVISORY REMAINS IN EFFECT UNTIL 1 PM EST FRIDAY...
* LOCATIONS...The North Carolina mountains along and west of the Blue Ridge Escarpment, plus the mountains of far northeast Georgia.
* HAZARDS...Strong and gusty winds.
* TIMING...Through Friday morning.
* WINDS...South 10 to 20 mph with gusts up to 50 mph.
* IMPACTS...Strong winds may blow down limbs, trees, and power lines. Scattered power outages are expected.
PRECAUTIONARY/PREPAREDNESS ACTIONS...
A Wind Advisory means that winds of 35 mph are expected. Winds this strong can make driving difficult, especially for high profile vehicles. Use extra caution.
