moisture indices ranged from -1 to -1.9, indicative of abnormally
dry conditions.

.HYDROLOGIC CONDITIONS...

Streamflows on the North Platte River, Encampment River and
Lodgepole Creek were observed at below normal to much below normal
(<10th to 24th percentile). Near normal flows (25th to 75th
percentile) were observed above Seminoe Reservoir near Sinclair,

.ENSO/PRECIPITATION/TEMPERATURE OUTLOOKS...

Below average sea surface temperatures strengthened in the east-
central Pacific Ocean. The average weekly Nino-3.4 index ranged from
-1.0 to -1.8 degrees Celsius. There is a 76 percent chance of La
Nina during the Northern Hemisphere Winter (December 2022 to
February 2023), with a 57 percent chance for transition to ENSO-
neutral in February to April 2023.

The November 2022 outlook issued by the Climate Prediction Center
favors equal chances of above, below and normal temperatures. Equal
chances of above, below and normal precipitation are favored for
all but far western areas with a 33 to 40 percent chance of above
normal precipitation.

The November 2022 through January 2023 outlook favors a 33 to 40
percent chance of above normal temperatures and equal chances of
above, below and normal precipitation.

The U.S. Winter Outlook December 2022 through February 2023 issued
October 20 favors equal chances of above, below and normal
temperatures and precipitation.

The seasonal drought outlook through January 2023 favors a
continuation of drought conditions.
