The Flash Flood Watch continues for

* portions of Colorado and Utah, including the following areas,
in Colorado, Animas river basin, central Colorado River Basin,
central Gunnison and Uncompahgre river basin, debeque to Silt
corridor, Flat Tops, Four Corners/upper Dolores river, Gore
and Elk Mountains/Central Mountain valleys, Grand Valley,
grand and battlement mesas, northwest San Juan Mountains,
Paradox Valley/lower Dolores river, Roan and tavaputs
plateaus, San Juan river basin, southwest San Juan Mountains,

* Through Tuesday evening

* scattered to numerous thunderstorms with heavy rain are expected
over the watch area. With a moist airmass in place, the threat
for heavy rainfall will continue into the overnight hours.
Another round of afternoon thunderstorms is expected on Tuesday
afternoon lasting through midnight Tuesday night.

* Flash flooding due to heavy rainfall is possible, especially
over already saturated soils and areas of steep terrain. Steep
canyons, burn scars, and normally dry streams, washes and
arroyos are most susceptible to flash flooding. Water can rise
quickly downstream of heavy rain, even when a thunderstorm is
miles away. Rock and mud slides, and high water flowing across
roads, are also possible which could impact travel.

Precautionary/preparedness actions...

A Flash Flood Watch means that conditions may develop that lead
to flash flooding. Flash flooding is a very dangerous situation.

You should monitor later forecasts and be prepared to take action
should flash flood warnings be issued.
