Severity: Severe. Certainty: Possible.
* WHAT...Flooding caused by excessive rainfall continues to be
possible.

* WHERE...A portion of southwest Colorado, including the following
areas, Northwest San Juan Mountains, San Juan River Basin and
Southwest San Juan Mountains.

* WHEN...Through late Wednesday night.

* IMPACTS...Flooding will be possible over burn scars, at low-water
crossings, and along creeks, streams, washes, arroyos and other
flood-prone locations. Creeks and streams may rise out of their
banks. Unpaved roads could become muddy and impassable.

* ADDITIONAL DETAILS...
- Periods of heavy rainfall, associated with remnant moisture from
Hurricane Polo, are expected to produce numerous showers and
embedded thunderstorms. Heavy rain falling on saturated soils and
burn scars could lead to localized flash flooding and rises on
local rivers. Rainfall is expected to end by late Wednesday, but
rivers may rise out of their banks overnight Wednesday even after
rainfall has ended.
