Full text

* WHAT...Flooding caused by excessive and long duration rainfall. * WHERE...All of northern and central Arizona. * WHEN...From Sunday evening through Tuesday evening. * IMPACTS...Flooding will be possible over burn areas, low-water crossings, creeks, streams, washes and swimming holes. Larger creeks and rivers may exceed bankfull. Flooding of paved roads and highway underpasses will be possible. Unpaved roads could become muddy and impassable. * ADDITIONAL DETAILS... - Low pressure will interact with tropical moisture from the eastern Pacific. This could potentially produce numerous showers and embedded thunderstorms, with heavy rain that will fall over saturated soils and burn scars. This could lead to localized flash flooding and rises on local rivers, such as the Little Colorado River. - Additional information is available at weather.gov/flagstaff.

What to do

You should monitor later forecasts and be alert for possible Flood Warnings. Those living in areas prone to flooding should be prepared to take action should flooding develop.

What this means

Warning
The hazard is happening or about to. Act now: a tornado warning means take shelter, a flash flood warning means move to higher ground.
Watch
Conditions favor the hazard. Nothing is happening yet; have a plan and be ready to act if a warning follows.
Advisory
A hazard that is less serious than a warning but can still cause trouble, such as dense fog, heat or light ice.
Statement
Information about weather that does not yet meet a warning: a strong storm, a hydrologic update, or a special weather statement.

Severity (extreme, severe, moderate, minor) is the rating the issuing office gives each product. More on the difference: tornado watch vs. tornado warning. Alerts come from the National Weather Service; follow its instructions and your local officials.
