HEAVY RAIN...Rainfall amounts of up to 3-6 inches are likely in
the Sierra through Tuesday morning, with 1-2 inches in the valleys
of northeast CA and western NV and 2-3 inches in the foothills
west of Highway 395. For northwest and west central NV, between
0.50 and 1 inch is probable north of US-50 with less than 0.50
inch south of US-50. Heavy rain is expected to bring widespread
flooding concerns to the region—including small stream flooding,
urban flooding, mud and rock slides, as well as increases to
mainstem rivers. See our hydrology section below for more details
on flooding.
.HYDROLOGY...
. Major flooding now expected for the Middle Fork of the Feather
River near Portola.
. Truckee River at Reno and Vista along with the Carson River near
Carson City and Susan River at Susanville forecast to reach
monitor stage.
. Flooding likely for creeks, streams, urban areas and drainage
basins in the Tahoe Basin, eastern Sierra, northeast California
and western Nevada early Monday through early Tuesday.
A strong atmospheric river will push into the region today through
through Tuesday morning bringing heavy rain and rising snow levels.
Currently, snow levels are expected to be around 6500 feet in
northeast California and around 7500 feet for much of the Sierra and
western Nevada. Precipitation totals in the Sierra could reach 3 to
6 inches, with 2 to 3 inches in the Carson Range and much of the
Susan, Pit, and Middle Fork of the Feather river basins. 1 to 2

Thanks for the report !
Post from freedom_is_not_free, about the evac order last week; they’re in the area of the dam...

As I posted on the Central Valley thread:
Okay, good morning everyone. As one who has followed this event with interest it looks like Oroville is still holding on this morning.
Based upon Lake measurements, it appears inflow has fluctuated between 47k and 23k cubic feet per second. Operators have been holding outflow over the main spillway to 59,900 cfs or thereabouts. This has kept lake levels falling very slightly from 851.17 to 849.54 or a decline of 1’ 7 1/2”.
Rainfall in the tributary area continues with Brush Creek, Four Trees and Buck’s Lake showing 24 hour rainfall running 2.4, 2.7 and 2.9 on the main fork of the Feather. Quincy and Grizzly Ridge have received about 1.5 inches. Gauges at Buck’s Creek and Lake Davis are not reporting data but areas surrounding them are less than critical.
Beale AFB radar:
https://radar.weather.gov/radar_lite.php?rid=bbx&product=N0R&loop=yes
Shows the more intense storms in the Folsom Reservoir drainage but higher elevation hills shade out some readings east of Oroville.
Clicking the eastern link shows Reno radar showing even distribution of precipitation across the western Sierras.
San Francisco Bay radar
https://radar.weather.gov/radar_lite.php?rid=mux&product=N0R&loop=yes
Shows the storms making landfall to be heavier south of the main urban area with Flash Flood warnings south of Monterrey Bay. I believe the coast highway is still closed for the bridge problems at Pfeiffer Canyon so travel there is very limited.
A prayer is offered for the next 72 hours that the Rivers don’t rise and the dam holds.
