Watch (FFA, WGUS63 KLMK) |
Flood Watches are issued as needed to inform the public of
conditions which may cause flooding in the next one to two
days. A Flood Watch indicates that there is threat of
flooding, but the occurrence is neither certain nor
imminent. Flood Watches may cover large geographic areas and
will be updated with Flood Statements.
A flood watch is issued if the following conditions occur during
the first 48 hours of the forecast period...
- Meteorological, soil, and/or hydrologic conditions indicate
it is possible but not certain,
- The geographical area covered by a pre-existing flood watch
increases or decreases, or
- A dam or levee may fail threatening lives or property, but
the threat is not deemed imminent.
If you are in the flood watch area, you are advised to check flood
action plans, keep informed, and be ready to take necessary
actions if a warning is issued and/or flooding is observed.
The flood watch will contain...
- The counties or geographical area covered by the watch (this
should be described in terms of well-known river basins,
counties, or portions of states),
- The effective time of the watch expressed in terms of hours
or in general terms, such as this evening,
- The extent of the hazardous condition expected, i.e.,
localized or widespread,
- The severity of the hazardous condition expected when this
can be done with sufficient degree of confidence; and
- Call to action statements.
