...Warm Temperatures this Week May Lead to Flood Impacts from
Efficient Low and Mid Elevation Snowmelt...

Temperatures will continue to run well above average through
Thursday, increasing low and mid elevation snowmelt and runoff.
Standing water in typical low spots can be expected, and we`ll also
likely begin seeing the swelling of smaller creeks and tributaries
that feed the larger streams and rivers. This may even push some
streams and creeks above bankfull causing minor flooding and bank
erosion due to the higher flows.

The warm temperatures will peak Wednesday with afternoon highs
reaching well into the 60s in most locations, and into the 70s in
some lower valleys. These will be the warmest readings of the year
thus far, challenging daily records. Overnight low temperatures will
be anomalously warm as well, remaining well above freezing through
Thursday night, exacerbating snowmelt through the overnight hours.

A cooldown is forecast to arrive late in the week with temperatures
Friday and Saturday dipping back down toward normals, and overnight
lows back to near freezing by Saturday morning. This cooldown,
however, will be accompanied by increasing rain chances which could
add to the runoff concerns.

Stay away from fast moving water, swollen river banks, and never
attempt to cross flowing water over roadways.

...Warmer than normal temperatures will allow for enhanced snowmelt
and subsequent runoff this week...

As high pressure builds across the Great Basin through the
beginning of the week, near to record warm high temperatures are
forecast. This will help to increase the melt rate of mid- and
high-elevation snowpack, which will make it into area creeks and
streams. Faster responding creeks that will need to be watched for
higher flows include Martin Creek in Humboldt county, the Owyhee
River, Bruneau River, and Salmon Falls Creek in Elko county. Though
flooding is not expected at this time, water in area creeks and
streams will be flowing strongly thru at least midweek. Residents
and outdoor enthusiasts are urged to use caution when walking along
riverbanks as run off water will be flowing rapidly with cold spring
melt water. Hypothermia can occur rapidly if someone were to fall in
while swift flows can carry a person downstream.
