.A strong and slow moving fall storm system will impact the region
from Friday night through Sunday. Well above normal atmospheric
moisture levels combined with the dynamics from this storm system
will provide the potential for heavy rainfall during this period.
Thunderstorms embedded in the more general rainfall will have the
potential to produce flash flooding, particularly over recent burn
scars.
