* WHAT...Flooding caused by excessive rainfall continues to be possible. * WHERE...Areas along and west of the central mountain chain including the west slopes of the Sangre de Cristo Mountains, the Sandia/Manzano Mountains, and the south-central mountains, as well as the Rio Grande Valley westward to the Arizona border. Some metro areas and locales include, Albuquerque, Santa Fe, Espanola, Taos, Socorro, Ruidoso, Los Alamos, Grants, Gallup, and Farmington. * WHEN...From Monday afternoon through late Tuesday night. * IMPACTS...Excessive runoff may result in flooding of rivers, creeks, streams, and other low-lying and flood-prone locations. * ADDITIONAL DETAILS... - A near-record to record surge of moisture combined with two merging storm systems will bring a prolonged multi-day period of showers and thunderstorms producing moderate to heavy rainfall. Combined with already rain-soaked soil, there is a moderate to high risk of flash flooding. - Low-lying, poorly drained areas, urban areas and arroyo systems will be most susceptible. Rivers and streams will see rises, potentially reaching flood stage. Recent burn scars may see flash flooding, including the Ruidoso area burn scars, Frijoles, Sacaton, Hummingbird, and Whiskey burn scars. - http://www.weather.gov/safety/flood

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.
