Severe Thunderstorm Warning: Issued when severe weather has been identified on
Doppler Weather Radar or reported by someone in or near the storm(s)...such as a trained
storm spotter. With a warning in effect, dime size hail or larger and/or damaging winds
(58 mph or greater) are expected. Tornado Warning:
Issued when a tornado has been identified on Doppler Weather Radar or reported by someone
in or near the storm(s)...such as a trained storm spotter. With a warning in effect, a
tornado is expected and may be accompanied by other severe weather such as dime size hail
or larger and/or damaging winds (58 mph or greater).
>>>Note<<<
Severe Thunderstorm Warnings and Tornado Warnings should not be confused with Severe
Thunderstorm or Tornado Watches. The Watches imply that severe weather is possible but not
imminent...and are posted to give people time to prepare for severe weather should it
materialize. The Warnings take matters one step further, and imply that severe weather is
imminent.
Flash Flood Watch: Issued when conditions are favorable for flash
flooding...with excessive rain possible but not imminent. By excessive, it is meant that
rainfall rates exceed what the ground can hold...with water running from the ground into
creeks and streams and across roads.
Flash Flood Warning: Issued when
excessive rain has occurred...with flash flooding imminent. With a warning in effect,
people are urged to leave areas near rapidly rising creeks and streams...and are advised
not to cross roads covered by water.
Flash Flood Statement: Issued to update conditions when a Flash Flood Watch and/or Warning is in effect...or when
mainly urban flooding (i.e. street flooding) is expected or is occurring (issued as an
"Urban and Small Stream Flood Advisory"). A Flash Flood Statement is also issued
to cancel all or part of a Flash Flood Watch or Warning.
Short Term Forecasts: Issued mainly when
precipitation is occurring somewhere in the Little Rock County Warning Area, but may also
be generated during significant non-precipitation events (i.e. areas of dense fog/freezing fog
forming). The forecast describes what is expected up to 6 hours into the future, and is designed
to help people keep track of changing weather conditions.
Hazardous Weather Outlooks: Issued at least once a day (around 5 am),
and advises people of possible hazardous conditions in the next 7 days. Hazards include severe thunderstorms,
winter weather, non-precipitation events (i.e. strong winds, excessive heat, dense fog, etc.), extremely
dry conditions (i.e. leading to fires) and flooding.
Severe Weather Statements: Issued to help
people monitor severe weather trends when a Severe Thunderstorm or Tornado Warning is in
effect, with descriptions of storm location and what the storm has produced (i.e. large
hail, damaging winds, etc). The Severe Weather Statement is also used to cancel warnings
when storms have weakened.
Watch County Notification Message: Issued to indicate what counties are
affected by a Severe Thunderstorm or Tornado Watch. This product is also used to clear counties
once severe weather has passed.
Winter Weather Message: Issued when
hazardous Winter weather is possible (i.e. Winter Storm Watch) or imminent. When hazardous
Winter weather is imminent, the message may cover a variety of conditions depending on
what is expected. Warnings usually imply that heavy snow (at least 4 inches in 12 hours/6
inches in 24 hours) and/or ice (significant accumulations) are expected, with travel not
recommended. Advisories imply that lesser snow and/or ice are expected, with perhaps some
travel delays resulting.
Non-precipitation Message (Weather Message):
Issued when significant non-precipitation events are expected, such as dense fog (or
freezing fog), high winds, extreme wind chills/heat index values, and freezes during the
growing season. |
