The Flash Flood Watch is now in effect for

* Portions of central and north central Colorado, including the
following areas, in central Colorado, Grand and Summit Counties
Below 9000 Feet and South and Southeast Grand/West Central and
Southwest Boulder/Gilpin/Clear Creek/Summit/North and West Park
Counties Above 9000 Feet. In north central Colorado, Jackson
County Below 9000 Feet, Larimer and Boulder Counties Between 6000
and 9000 Feet, South and East Jackson/Larimer/North and Northeast
Grand/Northwest Boulder Counties Above 9000 Feet and West Jackson
and West Grand Counties Above 9000 Feet.

* Through Saturday evening.

* Thunderstorms will become more numerous across the mountains and
foothills by this afternoon, and will have potential to produce
flash flooding. The highest threat areas would be the Cameron
Peak, East Troublesome, Williams Fork, and Calwood burn areas, but
flash flooding will even be possible in non-burn scar areas due to
the intensity of the rainfall. Rainfall amounts around 1.5 inches
will be possible in less than an hour. While storms should
gradually diminish overnight, there is still a threat of heavy
rain continuing in the foothill areas overnight into early
Saturday morning. Additional rounds of showers and storms can be
expected Saturday afternoon and evening.

* Burn scars will be particularly susceptible to heavy rainfall,
leading to quick runoff and debris and mud flows. The flood threat
may last through the night.


Have multiple ways to receive warnings, including television,
weather radio, phone, family, and friends. Avoid burn areas in
particular, and be ready to move to higher ground.
