Hydrologic Outlook issued February 22 at 5:15AM MST by NWS Boise ID

ESFBOI

Moderate to heavy rain and low elevation snowmelt Sunday and
Monday will lead to rises on rivers, creeks, and streams across
portions of southeast Oregon and southwest Idaho (particularly
the Weiser River Basin). Saturated or frozen soils in some areas
will increase runoff. Snow and ice may clog culverts and ditches
causing water to back-up and pond in low lying and poor drainage
areas. Additionally, ice jams could develop on any rivers, creeks,
or streams with existing ice cover and cause localized flooding.
Rivers in these areas will continue to run high through next week
with some waterways potentially reaching bankfull.

Stay tuned to the forecast for the latest temperature and
precipitation trends, along with any warnings or advisories that
may be issued.
