* ADDITIONAL DETAILS...
- A dangerous surge of monsoon moisture will arrive today and
Wednesday with widespread heavy rain.  Scattered occurrences of
flash flooding are likely, and there will probably be some main
stem river and tributary flooding later in the week, as the most
likely rain amount by Wednesday afternoon exceeds 1.5 inches many
locations along and east of the central mountain chain, and 1
inch in many locations westward to around Dulce, Gallup, and
Glenwood. Stronger storms will produce torrential rainfall at
rates over 2 inches per hour, and storms will train repeatedly in
succession over some locations, with locally heavier rain amounts
reaching over 4 inches over portions of southern, central, and
eastern New Mexico.  Heavy rain will likely continue Wednesday
night over north-central and eastern New Mexico, then showers and
storms with locally heavy rainfall are forecast to return to much
of the state again on Thursday.
- Rapid runoff and flash flooding will be most likely in complex
terrain, below recent burn scars, low-lying areas, urban areas,
normally dry arroyos, and near rivers and streams.  As the event
unfolds, locations with saturated ground will also become prone
to rapid runoff and flash flooding from additional rounds of
storms.
