SOUTH CENTRAL OREGON...

WASHINGTON...

.SYNOPSIS:

.Drought intensity and extent:
August is a climatologically dry month in the Pacific Northwest,
and predominantly near- to below-normal precipitation with much-
above-normal temperatures were observed. Long-term drought
indicators led to a small, 1-class degradation to drought
conditions in south-central Washington. No appreciable changes to
drought were observed across Oregon.

According to the U.S. Drought Monitor released on September 8th,
exceptional drought covers an area of central Oregon. Moderate to
extreme drought continues to occupy portions of central OR and
east-central Oregon.

Drought declarations are in effect or are in progress for Wasco,
Jefferson, Deschutes, Crook, Wheeler, Gilliam, Morrow, Grant,
Union, and Wallowa counties of Oregon.

The latest seasonal drought outlook indicates that drought
conditions will persist outside of the Lower Columbia Basin, Blue
Mountains and adjacent foothills, and portions of south-central
and southeast Washington.

Drought Impact Reports can be found via the U.S. Drought Portal
in the related websites section.

.Hydrologic Conditions and Climate Summary:

Since October 1, 2021, precipitation has been 25 to 75 percent of
normal from central Oregon into the central Oregon mountains.
Portions of north-central Oregon into the Lower Columbia Basin
and the Blue Mountains are seeing 100 to 200 percent of normal
precipitation due to the wet April through early June period.

Average temperatures across the region in August ranged from 3 to
6 degrees above normal with most locations seeing temperatures 5
to 6 degrees above normal.

Streamflows have begun to show signs of the hot, dry summer with
the majority of USGS gaging stations across central, north-
central, and southeast Oregon reporting near or below normal.
Despite the hot, dry summer, the wet spring has allowed
predominantly above-normal streamflow to remain across the
Northern Blue Mountains and their foothills and further west for
streams and rivers emanating from the Washington Cascades in
south-central Washington.

Seasonal snowpack has melted for the summer.

The outlook for September from the Climate Prediction Center calls
for increased chances of above-normal temperatures. Increased
chances of below-normal precipitation are also favored, except for
equal chances in far northwest Oregon and northwest Washington,
including the central Washington Cascades.

In the Climate Prediction Center`s three month outlook for
September through November, odds are tilted toward above-normal
temperatures across Oregon and southern Washington with equal
chances of above- or below-normal precipitation. Equal chances of
above- or below-normal temperatures with above-normal
precipitationare favored for northwest Oregon and northwest
Washington, including the central Washington Cascades.
