* 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, 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.
