The National Weather Service in Greenville-Spartanburg has issued a wind advisory and flash flood watch in effect from Monday morning to Tuesday morning for the mountains of western North Carolina.
The flash flood watch includes Henderson, McDowell Mountains, Polk Mountains, Rutherford Mountains, Southern Jackson, Transylvania, upstate South Carolina and Oconee Mountains.
Showers associated with the outer rain bands of Irma move in from the south on Monday. Rainfall intensity will be enhanced along the Blue Ridge escarpment due to very strong east to
southeast winds above the surface. Rainfall amounts of 3 to 4 inches, with local amounts as high as 6 inches will be possible by the time the rainfall rates taper off early Tuesday morning. This could be enough for flash flooding to develop.
Strong winds will combine with increasingly saturated soils to bring down some trees and possibly power lines. Winds will increase Monday morning, and become strong by the
afternoon. The strong winds will continue into the evening northeast from 20 to 30 mph and gusts up to 45 mph. Strong winds may blow down limbs, trees and scatter
loose outdoor objects.
A wind advisory means that winds of 35 mph are expected. Winds this strong can make driving difficult, especially for high-profile vehicles. Use extra caution.
