* Excessive runoff could lead to flooding along creeks and rivers across the area.
Precautionary/preparedness actions...
A Flood Watch means that flooding is possible but not imminent in the watch area. People in the watch area are urged to check on preparedness requirements... especially if you have interests along area rivers. Stay informed... and be ready for action if flooding is observed or if a Flood Warning is issued.
