Breaking down weather alerts: advisories, watches, and warnings
- Flash flood warning: Take action!
A flash flood warning is issued when a flash flood is imminent or occurring. If you are in a flood-prone area, move immediately to high ground. A flash flood is a sudden violent flood that can take from minutes to hours to develop. It is even possible to experience a flash flood in areas not immediately receiving rain.
- Flood warning: Take action!
A flood warning is declared when flooding is on the verge of happening or is already underway.
- Flood advisory: Be aware:
A flood advisory is released when flooding is not expected to reach a severity level necessitating a warning. Nonetheless, it can still cause considerable inconvenience and, without exercising caution, potentially lead to situations that threaten life and/or property.
- Flood watch: Be prepared:
A flood watch is issued when conditions are favorable for flooding. It does not mean flooding will occur, but it is possible.
