Greenville, South Carolina – Drivers across the Upstate and into western North Carolina could face dangerous flooding and water-covered roads overnight and into Tuesday morning, as torrential rain targets the I-85 corridor from Seneca to Greenville and Anderson.
According to the National Weather Service in Greenville-Spartanburg, heavy downpours are expected after midnight and will persist through noon Tuesday, with 2 to 4 inches of rain likely in the yellow-shaded zone on the latest outlook. A few localized areas, especially near the southern escarpment and north of I-85, could exceed 4 inches, raising the risk of isolated flash flooding.
Greenville, Spartanburg, Anderson, Seneca, and Gaffney are in the highest impact zone, while communities in western North Carolina, including Asheville and Waynesville, can expect 1 to 2 inches of rain. Urban areas, low-lying roads, and underpasses are most at risk for water accumulation, especially before sunrise when flooding is hardest to spot. Emergency officials urge residents to avoid non-essential travel, never drive through flooded roadways, and monitor local alerts overnight.
While the heaviest rain should ease by Tuesday afternoon, the risk of new advisories remains if storms redevelop. Updates will be issued as conditions change.
