Daily Weather Briefing for Thursday, February 21, 2019
Flood Watch Warning Added


**6:47am** A Flood Warning has been issued for portions of southern Macon County. The rain gauge at Riverside Road in Otto is nearing Flood Stage. While it may not be raining that much in Macon County, it will continue to rain upstream in Georgia so the water level will continue to rise for a bit before going back down.



BULLETIN - IMMEDIATE BROADCAST REQUESTED
Flood Warning
National Weather Service Greenville-Spartanburg SC
646 AM EST THU FEB 21 2019



The National Weather Service in Greenville-Spartanburg has issued a

* Flood Warning for Small Streams in...
South central Macon County in western North Carolina...

* Until 1245 PM EST Thursday.

* At 644 AM EST, Doppler radar and automated rain gauges indicated that heavy rain was falling over the area. The stream gauge at the Little Tennessee River near Otto reported a height of 16.9 feet. Flood stage is 17 feet.

* Some locations that will experience flooding include...
Otto and Scaly Mountain. At 17 feet, Riverside Road will be flooded.

PRECAUTIONARY/PREPAREDNESS ACTIONS...

Most flood deaths occur in vehicles. Do not attempt to cross water-covered roadways, bridges, or low-level crossings. Only a few inches of rapidly flowing water can carry away your vehicle. It is not worth the risk. Please TURN AROUND, DON'T DROWN.

In hilly and mountainous terrain, there are hundreds of low-water crossings which can be dangerous in heavy rain. Low-water crossings can be submerged by flood waters quickly and without warning. Never attempt to travel across flooded crossings. Find an alternate route. It takes only a few inches of swiftly flowing water to carry vehicles away.

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.






Outlook

Chilly high pressure atop the region will weaken through tomorrow as a series of low-pressure systems move up from the Gulf. The moist pattern will continue well into the weekend until a cold front finally moves through the region Sunday. After a brief break early next week, another system will approach by mid-week.

URGENT - IMMEDIATE BROADCAST REQUESTED
Flood Watch
National Weather Service Greenville-Spartanburg SC
331 AM EST Thu Feb 21 2019

...PERIODS OF RAIN WILL CONTINUE TODAY THROUGH FRIDAY...

.A very moist pattern will persist across the region, producing rounds of moderate to locally heavy rain through the end of the work week. Soils have become saturated across the western Carolinas and northeast Georgia. So each additional round of rain is producing more rapid responses in stream levels, and there is an increased threat for flooding across the area.


...FLOOD WATCH IN EFFECT THROUGH FRIDAY EVENING...

The National Weather Service in Greenville-Spartanburg has issued a Flood Watch for portions of northeast Georgia, western North Carolina, and upstate South Carolina through Friday evening

* Additional moderate to locally heavy rain falling on saturated soils, is producing rapid river and stream level responses. Additional rainfall totals of 1" to 2" are likely across the watch area today through Friday, most of which will be runoff.

* Flooding of area streams and mainstem rivers will likely inundate low-lying areas adjacent to streams, including farmland, parks, and campgrounds. Flooding is most likely along the upper French Broad River and associated tributaries. Periods of heavy rain can overwhelm or clog storm drains and ditches with debris and cause extensive street flooding and road ponding. This is especially true this time of year as fallen leaves block or impede drainage systems.

PRECAUTIONARY/PREPAREDNESS ACTIONS...

A Flood Watch means there is a potential for flooding based on current forecasts.

You should monitor later forecasts and be alert for possible Flood Warnings. Those living in areas prone to flooding should be prepared to take action should flooding develop.

This is a new segment that Macon Media will be testing for possible inclusion as an everyday or weekly addition to the Daily Weather Briefing.

The Earth is beginning to exit a stream of solar wind that has been buffeting our planet's magnetic field since Jan. 31st. The stream is a wide one, so the exit will be slow. Solar wind speeds are expected to remain near 500 km/s through Feb. 4th, boosting the chances of Arctic auroras.
