Greenville, South Carolina — Rain is shifting south across upstate South Carolina Saturday, with the heaviest rainfall between 10 a.m. and 3 p.m. creating slick roads and reduced visibility in Greenville, Spartanburg, Anderson, Gaffney and Greenwood.
According to the National Weather Service in Greenville-Spartanburg, the highest rainfall totals will occur along and south of Interstate 85, where steady rain will continue through early afternoon before tapering off.
This is part of a broader system pushing cooler air into the Carolinas, setting up a quick transition from wet conditions to chilly overnight temperatures.
Rainfall may quickly pool on low-lying roads and flood-prone intersections, especially near urban corridors along I-85 where drainage can be overwhelmed. Visibility may drop during heavier bursts, slowing travel and increasing crash risk through the midday hours.
Behind the rain, temperatures will fall overnight into the mid-30s across the mountain valleys near Asheville and Boone, where patchy frost may develop in sheltered areas and along higher elevations.
Drivers should slow on wet roads and avoid water-covered areas today, while mountain residents should cover sensitive plants before temperatures drop overnight.
The most immediate travel impacts will occur between 11 a.m. and 2 p.m., when rainfall is heaviest along the I-85 corridor.
