This hazardous weather outlook is for eastern Utah and western
Colorado.

.DAY ONE...This Afternoon and Tonight

Scattered to numerous thunderstorms will continue over the higher
terrain well into the evening. Severe weather is not expected,
however some cells will be capable of generating excessive
rainfall which may lead to rock fall and debris flows in steep
terrain. Fresh burn scars, most notably from the 416, Burro and
Lake Christine fires are particularly susceptible to debris flows
and flash flooding.

A Flash Flood Watch is in effect for the southern mountains of
Colorado and the 416 and Lake Christine burn scars.

.DAYS TWO THROUGH SEVEN...Monday through Saturday

A Flash Flood Watch is in effect for the 416 Fire burn scar area
Monday afternoon and evening. Though the chance of storms will
decrease across most of the area, enough moisture will remain over
southwest Colorado for scattered thunderstorm development on the
south side of the San Juan Mountains. These could produce locally
heavy rain over the 416 burn scar area.

Isolated to scattered afternoon and evening thunderstorms will be
possible each day the rest of the week, mainly over the
mountains.

.SPOTTER INFORMATION STATEMENT...

Spotter activation will not be needed.

...THE FLASH FLOOD WARNING REMAINS IN EFFECT UNTIL 500 PM MDT FOR
CENTRAL OURAY...NORTHEASTERN SAN MIGUEL AND SOUTH CENTRAL MONTROSE
COUNTIES...

At 350 PM MDT, Doppler radar indicated showers and thunderstorms
producing moderate rain across the warned area and estimated that
between 1.5 and 2.5 inches of rain has fallen since 130 pm.

Excessive rainfall over the warned area has caused and will continue
to cause high stream flow, and water and mud flows on Highways 62
and 145. The mud slides can consist of rock, mud, vegetation and
other loose materials. People near Leopard Creek and McKenzie Creek
should be on alert for flash flooding in those creek basins.

Some locations that will experience flooding include...
Fall Creek and Placerville.

This includes the following highways...
 Colorado 62 between mile markers 1 and 13.
 Colorado 145 between mile markers 83 and 96.

PRECAUTIONARY/PREPAREDNESS ACTIONS...

Turn around, don`t drown when encountering flooded roads. Most flood
deaths occur in vehicles.

Excessive runoff from heavy rainfall will cause flooding of small
creeks and streams, country roads, farmland and other low lying
spots.

Heavy rainfall triggers rockslides, mudslides and debris flows in
steep terrain.

A Flash Flood Warning means that flooding is imminent or occurring.
If you are in the warned area move to higher ground immediately.
Residents living along streams and creeks should take immediate
precautions to protect life and property.
