Flood Advisory issued September 17 at 1:21AM EDT until September 17 at 8:00AM EDT by NWS Greenville-Spartanburg SC

* WHAT...
Flooding caused by excessive rainfall continues.

* WHERE...
Union County, North Carolina.

* WHEN...
Until 800 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 120 AM EDT, Doppler radar and automated rain gauges indicate that the heaviest rain bands from a weak coastal low have moved well to the west of Union County. Widespread 2.5-3.5" accumulations occurred across the county in about 6 hours, resulting in excessive runoff and rapid rises on area streams. Several streams exceeded bankfull conditions, and several streamgauges exceeded Action Stage, resulting in nuisance flooding of adjacent low-lying areas. Streamgauges along North Fork Crooked Creek at Poplin Rd, South Fork Crooked Creek at Idlewild Rd in Hemby Bridge, and Bearskin Creek near N Charlotte Ave in Monroe indicate that nuisance flooding adjacent to these streams continues and that floodwaters have yet to crest. Nuisance flooding of farmland, woodlands, parks, and greenways will continue for the next 2-4 hours as it will take some time for larger streams to crest and recede back below bankfull levels.
Therefore, the Flood Advisory will remain in effect until flood conditions improve.
Confidence is increasing that the heavy rain threat from this low-pressure system is over. However, a Flood Watch will remain in effect for the next few hours to ensure that anticipated bands of moderate rain develop north of Union County. Due to saturated soils and elevated stream levels, any additional bands of moderate to heavy rain would cause new areas of flooding to develop.
- Some locations that may continue to experience nuisance flooding include...
Monroe, Indian Trail, Weddington, Stallings, Unionville, Wesley Chapel, Wingate, Waxhaw, Marshville, Lake Park, Mineral Springs, Hemby Bridge, Marvin, Fairview, Sturdivants, Jaars and Trinity.
