No other rivers are expected to flood.

An Areal Flood Watch has been issued from 10:00 pm Friday through 10:00 pm Saturday. All low-lying areas of the county could be susceptible to ponding and pooling of water during this event. Small streams and rivers could overflow their banks due to the heavy rain and localized snowmelt. Gusty winds may also create power outage scenarios due to downed tree limbs and power lines.
