Flood Watch for Eastern Idaho
With rain and warming temperatures in the forecast, the National Weather Service in Pocatello has issued a FLOOD WATCH.
“A powerful Pacific storm is expected to bring significant
precipitation along with very warm temperatures Wednesday night
through Thursday night. Snow levels are expected to gradually rise
and reach 8,500 feet by Thursday morning. An atmospheric river
with this storm system is also expected to bring heavy rainfall
with many areas below 8,500 feet expected to get an inch or more
from Wednesday afternoon through Thursday night. The combination
of very warm temperatures and heavy rain will lead to flooding
potential in low lying areas throughout southeast Idaho.
Temperatures are expected to cool Friday behind a cold frontal
passage and through the weekend. The main flooding potential will
be on Thursday.
