The National Weather Service issues many hydrology related products. Some are to warn you of potential hazards; others are information statements to keep you up to date on changing weather and river situations. Below are the most commonly issued products along with a brief explanation of what they mean to you:

"Take Action!" when these products are issued

Warnings or Advisories are issued when confidence is greater than 80% that an event will occur. Depending on the type of event, these may be issued anywhere from hours before an event to days in advance of an event. +Flash Flood Warning +Flood Warning +Flood Advisory +Coastal/Lakeshore Hazardous Message +Special Weather Statement

"Be Prepared" when these products are issued

Watch products associated with flooding are typically issued within a day or more of the event. The confidence level for an event to occur when a Watch is issued is 50-80%. When a Watch is issued, you should begin to gather more information about the situation and determine what actions you will need to take should a warning be issued. +Flash Flood Watch +Flood Watch

"Be Aware" when these products are issued

Outlook products are issued days, weeks or even months in advance of the event. The confidence level for an event highlighted in an outlook to occur is less than 50%. When an Outlook is issued, you should take note. This serves as a "heads-up" that you may be impacted and gives you a general timeline of when the event could occur. +Hydrologic Outlook +Hazardous Weather Outlook
