...There is a Slight Risk (level 2/4) of excessive rainfall over parts of
the Southwest, Great Basin, and Central Rockies through Monday...

Monsoonal moisture will produce showers and thunderstorms with heavy rain
over parts of the Southwest, Great Basin, and Central Rockies through
Monday. Therefore, the WPC has issued a Slight Risk (level 2/4) of
excessive rainfall over parts of the Southwest, Great Basin, and Central
Rockies on Sunday and Monday.  The associated heavy rain will create
mainly localized areas of flash flooding, with urban areas, roads, small
streams, narrow canyons/gullies, and burn scars the most vulnerable.

A quasi-stationary front from the North Carolina Coast southwestward to
the Lower Mississippi Valley will slowly dissipate from west to east to
the North Carolina Coast by late Sunday morning. Near and south of the
front, showers and thunderstorms will develop over the Southern
Mid-Atlantic to the Southeast and Central/Eastern Gulf Coast through
Sunday evening. From Sunday night to Tuesday morning, showers and
thunderstorms will develop over the Central/Eastern Gulf Coast and into
parts of the Western Gulf Coast.

Showers and thunderstorms will also develop over the Northern High Plains
and into the Northern Plains through early Monday morning.  Additionally,
showers and thunderstorms will develop along and near a warm front
extending from the Great Lakes into parts of the Northeast and
Mid-Atlantic from Monday through Tuesday.  Lastly, scattered rain will
develop over parts of the Northwest Coast on early Tuesday morning.
