Weather experts said remnants of Tropical Storm Karen threaten the Upstate late this weekend, with heavy rain and severe thunderstorms possible before daybreak Monday.
Forecasters put the storm on a more eastward track, away from the region, once it moves into South Carolina, likely as a tropical depression.
Still, the National Weather Service said a strong cold front will approach the area from the west and begin to draw tropical moisture from Karen on Sunday night.
Forecasters said severe thunderstorms, flash flooding and tornadoes will continue to threaten as Karen’s remnants cross the Upstate.
