Western North Carolina and upstate South Carolina are in for double trouble this week with both a flooding and winter weather threat.
What you need to know:
An ample supply of moisture will keep things damp Thursday. Where temperatures drop below freezing, that rain could turn to sleet or freezing rain. The winter weather threat is mainly in the higher elevations.
All day and night Wednesday and Thursday we'll be rainy. Heavy rains and saturated grounds will cause a threat for flash flooding.
The counties seen here in green across North Carolina and South Carolina have flood watch. It includes the metropolitan areas of Greenville, Spartanburg, Asheville and Charlotte.
Total rainfall estimates are between one and three inches. Locally higher amounts are possible.
When temperatures drop below freezing Wednesday night through Thursday morning, some of that rain could freeze. The best chance of seeing this is in the western North Carolina mountains and foothills.
While some areas may see no ice accumulation, some of the coldest communities could see up to half an inch of ice coating by Thursday morning. All motorists should use caution when traveling and are advised to delay their travel until after sunrise Thursday.
A Winter Storm Watch has been issued for these counties in the western North Carolina mountains and foothills from Wednesday night into Thursday morning.
A strong upper level low pressure system in combination with deep tropical moisture and saturated soils will set up the potential for flooding and flash flooding. Due to the heavy rainfall the past several days, many creeks and streams are already near or above bankfull. Creeks and rivers could rise out of their banks, closing roads and impacting homes, businesses and farms. High water may not recede until well after the rain has ended.
