...Warming Temperatures into Early Next Week May Lead to Minor
Flooding Impacts from Snowmelt...

Temperatures will continue to warm into early next week, increasing
low elevation snowmelt and runoff, potentially leading to minor
lowland flooding. Locations most prone to rapid snowmelt include
areas below 6000 ft across the Eastern Magic Valley, Lower Snake
Plain, and South Hills, where snow pack still exists. In these
areas, the increased runoff on top of frozen or saturated ground may
lead to ponding of water or sheet flooding in low lying or poor
drainage areas, along with rises on small streams and creeks.

These warming temperatures will peak on Monday, with afternoon highs
reaching the 50s across the Eastern Magic Valley and Raft River
regions. Low temperatures tonight and Monday night are forecast to
remain above freezing, prolonging the melt cycle. While temperatures
will remain mild into mid next week, overnight lows are expected to
dip back below freezing by Tuesday night, slowing the melt. Ongoing
precipitation continues through tonight. Rainfall amounts up to 0.25
inches across lower elevations and up to 0.50 inches across higher
elevations in these areas will add to the runoff.

Make sure drains are cleared and move snow away from buildings to
minimize impacts. Stay up to date with the latest forecasts at
