While additional rainfall amounts of 0.5 to 1 inch are expected to be widespread across the watch area this afternoon, isolated locations are expected to see multiple rounds of very heavy rainfall, and localized amounts as high as 3 inches are possible, enhancing the potential for flash flooding in these areas. - http://www.weather.gov/safety/flood

A Flood Watch for flash flooding 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.

Flood Advisory issued July 23 at 11:55AM EDT until July 23 at 5:45PM EDT by NWS Greenville-Spartanburg SC

Effective: Thu July 23, 2026, 11:55 AM
Expires: Thu July 23, 2026, 5:45 PM

* WHAT...Nuisance to minor flooding caused by excessive rainfall is expected. * WHERE...Southeastern Mecklenburg County in the piedmont of North Carolina... Northern Union NC County in the piedmont of North Carolina... * WHEN...Until 545 PM EDT. * 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 1150 AM EDT, Doppler radar and automated rain gauges indicated heavy rain due to training heavy rain showers, which have produced between 1 and 2 inches of rainfall over the past 45-60 minutes. Nuisance to minor flooding is expected to begin shortly in the Advisory area. Areas of greatest concern include flood-prone areas from Matthews to Indian Trail to Hemby Bridge, especially within the Crooked Creek and Goose Creek watersheds. - Additional rainfall amounts of 1 to 2 inches are expected over the area. This additional rain may exacerbate flooding and may cause more significant flooding to develop. If storm-total rainfall amounts exceeds 3-4 inches over the next 1-2 hours, more significant flooding may develop and a Flash Flood Warning may be issued. Caution is advised near any stream or other vulnerable area. Seek higher ground immediately if streams start to rise. Please have a plan in place should flash flooding develop and do not hesitate to act. - Some locations that may experience flooding include... Matthews, Mint Hill, Indian Trail, Weddington, Stallings, Unionville, Wesley Chapel, Lake Park, Hemby Bridge, Fairview In Union County and New Salem. - Http://www.weather.gov/safety/flood

Turn around, don't drown when encountering flooded roads. Most flood deaths occur in vehicles. Be aware of your surroundings and do not drive on flooded roads. Stay away or be swept away. River banks and culverts can become unstable and unsafe.

Flood Advisory issued July 23 at 2:08PM EDT until July 23 at 5:45PM EDT by NWS Greenville-Spartanburg SC

* WHAT...Nuisance flooding caused by excessive rainfall may be ongoing. * WHERE...Southeastern Mecklenburg County in the piedmont of North Carolina... Northern Union NC County in the piedmont of North Carolina... * WHEN...Until 545 PM EDT. * 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. * ADDITIONAL DETAILS... - At 156 PM EDT, Doppler radar and automated rain gauges indicate earlier heavy rain across the Goose Creek and Crooked Creek watersheds has ended. Light showers persist across the Advisory area, but these showers will not exacerbate ongoing excessive runoff and stream rises. However, North Fork Crooked Creek and South Fork Crooked Creek continue to rise with bankfull conditions possible over the next 1-2 hours before these streams crest. Therefore, the Flood Advisory will remain in effect through at least 3pm to allow streams to crest and conditions to improve. Isolated areas of nuisance flooding may be ongoing in areas from Matthews to Indian Trail to Hemby Bridge, especially adjacent to the north and south forks of Crooked Creek. - Additional rounds of showers and thunderstorms are expected to develop through the early evening in the vicinity of the current Advisory area. These showers and storms will be very efficient at producing brief periods of heavy rainfall. Where earlier heavy rainfall has occurred, soils are saturated and streams are elevated. Therefore, additional heavy rain may quickly create new areas of flooding and cause previous areas of flooding to redevelop. Caution is advised near any stream or other vulnerable area. Stay weather aware through this evening and have multiple ways to receive Advisories and Warnings. - Some locations that may experience nuisance floodinginclude... Matthews, Indian Trail, Unionville, and Hemby Bridge. - Http://www.weather.gov/safety/flood
