Daily Weather Briefing for Tuesday, February 11, 2020





Outlook

A weak cold front will move very slowly southeast across the southern Appalachians today before stalling just to our south tonight. The boundary will move back north as a warm front through Wednesday night as another low-pressure system and attendant cold front approach from the west. This cold front, and the associated moisture, will cross the region late Wednesday night through Thursday, with cool and dry high pressure settling into the area Friday through Saturday. Yet another low-pressure system will approach from the west late in the weekend.

Further flooding could develop and existing flooding may worsen. We are currently under a Flood Watch and a copy is posted below for your convenience.


Flood Watch
National Weather Service Greenville-Spartanburg SC
320 AM EST Tue Feb 11 2020

...HEAVY RAINFALL AND POTENTIAL FLASH FLOODING THROUGH TODAY...

.A slow-moving frontal boundary will continue to bring moderate to heavy rainfall to the southwest North Carolina mountains, parts of northeast Georgia, and far western Upstate South Carolina today. With the ground saturated from heavy rainfall last week, and many streams running at elevated levels, additional flash flooding is expected to redevelop within the watch area today. In addition, some main stem river flooding is likely to develop within and close to the watch area.



...FLASH FLOOD WATCH REMAINS IN EFFECT THROUGH THIS EVENING...

The Flash Flood Watch continues for portions of northeast Georgia, western North Carolina, and
upstate South Carolina, including the following areas:

In northeast Georgia: Franklin, Habersham, Hart, Rabun, and Stephens.

In western North Carolina: Graham, Haywood, Macon, Northern Jackson, Southern Jackson, Swain, and Transylvania.

In upstate South Carolina: Anderson, Greater Greenville, Greater Oconee, Greater Pickens, Greenville Mountains, Oconee Mountains, and Pickens Mountains.

* through this evening

* Additional rainfall amounts through today are expected to range from 1 to 3 inches across the Piedmont, with locally higher amounts expected. In light of the saturated ground and elevated stream flows resulting from last week`s heavy rainfall, this rainfall will likely result in development of localized flash flooding, some of which could be significant.

* Rapid rises above bankfull on streams and creeks may occur, along with the threat of flooded roadways. Flooding is also likely to re-develop on main stem rivers in and close to the watch area.

PRECAUTIONARY/PREPAREDNESS ACTIONS...

A Flash Flood Watch means that conditions may develop that lead to flash flooding. Flash flooding is a very dangerous situation.
You should monitor later forecasts and be prepared to take action should Flash Flood Warnings be issued.
