Record rainfall totals across WNC, flood status, week following Helene: What we know

ASHEVILLE – Following the catastrophic flooding of Western North Carolina resulting from Tropical Storm Helene and a predecessor rainfall event, the National Weather Service is forecasting clearer skies as WNC works to repair affected communities.

As predicted by meteorologists, Helene brought widespread destruction to WNC, shattering records for rainfall and river levels over three days of driving rain and heavy winds. Many WNC residents were forced to evacuate to temporary shelters as landslides and flooding destroyed area homes.

Though the worst of the weather has passed, we may see more rain tonight. Here’s what the NWS is predicting for the week, rainfall amounts WNC received and more.

Flooding, weather forecast in WNC

After several days of devastating flooding in WNC, flood and flash flood warnings are beginning to end. In Asheville, one flood warning for the Swannanoa River at Biltmore affecting Buncombe County remains active until 1 p.m. Sept. 29.

Regardless of the status of warnings, a NWS hazardous weather outlook for Asheville issued at 3:28 a.m. the morning of Sept. 29 said that flooding continues to be a problem across portions of WNC. The alert advised residents to continue monitoring warnings and heeding all official instructions for evacuations and road closures.

Some scattered showers are expected today into tonight – and while the rainfall amounts are expected to remain light this time – less than 1 inch in Asheville – the alert warned that isolated excessive runoff is possible for areas that received heavy rainfall and flooding from Helene.

Beginning tomorrow, Monday, Oct. 1, the NWS alert said that no further hazardous weather was expected for the week as WNC works to restore power and water, distribute supplies to those in need and slowly repair extensive damage to affected communities.

NWS Meteorologist Doug Outlaw told the Citizen Times that the rainfall WNC saw beat the previous record for September in only three days.
