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 758 PM EDT, At 734 PM EDT, Light to moderate showers are moving from south to north across Henderson County, with heavier showers approaching from the south. Storm-total rainfall of the 3-4 inches have fallen over the past 12 hours. The rainfall has accumulated steadily, allowing soils to slowly saturate and runoff to slowly increase, resulting in steady rises in area streams including Clear Creek, Bat Fork Creek, Mills River, and Mud Creek. Streams are approaching bankfull conditions, and the streamgauge on Mud Creek below N Main St in Henderson County has just exceeded the Action/Advisory Stage of 11.5 feet. At this level, common, nuisance flooding of low-lying areas adjacent to Mud Creek is beginning. The lowest elevations of William H King Memorial Park are beginning to flood and floodwaters are approaching the lowest elevations of the Oklawaha Greenway. At this stage, more expansive lowland flooding with nuisance impacts to adjacent farmland, golf courses, and nurseries is ongoing closer to Erkwood Dr. Additional rounds of showers and thunderstorms are expected to develop over the next few hours and the threat will persist through the early morning hours on Sunday. These showers and storms will be very efficient at producing heavy rainfall. Soils are saturated and streams are swollen. Therefore, additional heavy rain may quickly create new areas of flooding and cause previous areas of flooding to redevelop. As a result, Flash Flood Warnings may be issued tonight. Caution is advised near any stream or other vulnerable area. Seek higher ground immediately if heavy rain develops. Please have a plan in place should flash flooding develop and do not hesitate to act. Please heed all evacuation orders from Emergency Management officials. Some locations that may experience nusiance floodinginclude... Hendersonville, Mills River, Fletcher, Flat Rock, Etowah, Mountain Home, Laurel Park, and Saluda.
