A Watershed Conditions Bulletin is issued to raise awareness about a change or potential change in conditions on local waterways.

A High Water Advisory is issued when there is potential for flooding to occur in low-lying areas. Municipal flood coordinators are notified that the potential for flooding exists.

A Flood Warning is issued when there is impending flooding. A Flood Warning requires action that may include the activation of the municipal flood emergency plan, warning residents or businesses in specific affected areas, and in some cases evacuation.
