Alerts

Flooding weather alerts will be posted HERE throughout the duration of the event.

A Flash Flood Watch has been issued by the National Weather Service from 6:00 p.m. tonight to 6:00 p.m. Wednesday. Locally heavy rain may produce rainfall amounts of 3 inches or more. If this occurs in a short period of time flash flooding may occur. Excessive runoff may produce rock and mudslides in steep terrain and fast flowing water may create life threatening situations.
