NWS Advisory Alert

National Weather Service
An unusually wet series of frontal systems are likely to impact
northern California and southern Oregon with widespread soaking
rains Saturday night through Monday night. The time period of
the heaviest rainfall is likely to be in the Sunday evening through
Monday time frame.

While confidence in specific rainfall amounts is only low to moderate
at this time…it is likely that total rainfall amounts during the
mentioned time period will be close to what normally falls during
the entire month of June in many areas. The usually drier Interior
Valley locations are expected to receive a half inch to an inch of
rain. Other portions of the area should receive one to three
inches of rain…with higher amounts expected across portions of
Siskiyou County.

Temperatures during this very wet episode will be 10 to 15 degrees
below normal for daytime highs…in the 60s and 70s in the
valleys…and in the 40s and 50s in the mountains. While snow
levels will generally remain above ten thousand feet…prolonged
exposure to these temperatures combined with the rainfall and
cloud cover can easily lead to hypothermia…especially on or near
area waterways and in the mountains.

Those planning outdoor activities Saturday night through Monday
night should consider either canceling plans or preparing well for
cool and very wet weather conditions. There is high confidence in
a significant rainfall event across the forecast area during this
time period.
