Greenville, SC – Parts of the western Carolinas received more than 9 inches of rain from Hurricane Isaias between Friday, October 9, and Monday, October 12, with the heaviest totals concentrated along the Blue Ridge Escarpment and nearby foothill communities.
According to the National Weather Service in Greenville Spartanburg, preliminary rainfall measurements show widespread accumulations of 4 to 8 inches across portions of western North Carolina and Upstate South Carolina.
The agency released an updated rainfall map Monday showing precipitation recorded from 8 a.m. Friday through 8 a.m. Monday.
Some locations exceeded 9 inches , with particularly heavy rainfall concentrated across the North Carolina foothills, northwest Piedmont and sections of Upstate South Carolina.
The Blue Ridge Escarpment, where mountain terrain transitions into lower elevations, was among the areas experiencing the greatest rainfall.
The preliminary map shows significant variations in precipitation over relatively short distances.
Several communities across the central and northern portions of the forecast region recorded totals between 6 and 8 inches, while nearby locations received considerably less.
The National Weather Service reported that rainfall was generally lighter across higher mountain areas and much of northeast Georgia.
Some western mountain locations recorded approximately 1 to 3 inches, highlighting the uneven distribution of precipitation associated with the storm.
The agency's rainfall analysis combines reports from weather stations, cooperative observers and other monitoring networks.
Forecasters cautioned that the map represents an interpolation of actual observations and should be considered an estimate rather than an exact measurement for every location.
The widespread heavy rainfall underscores the potential for significant runoff and saturated ground conditions in areas that received repeated downpours.
Residents in locations that experienced the highest totals should remain mindful of lingering water accumulation and changing stream conditions, particularly in low lying areas.
The rainfall figures remain preliminary and could be revised as additional observations are reviewed.
The National Weather Service has not provided confirmed regional damage or flooding totals in this update.
