OF the Pacific, in his weather review for
November, states that there were seven
areas of low pressure that moved toward
Or developed on the Pacific slope during
November, and that affected the weather
Of the section west Of the Rockies.
The month opened with wet weather
fn Washington, Oregon, Northern Cali
fornia and Nevada, and with disturb
ance developing on the upper Pacific
Coast that proved to be one of the worst
storms of the month, the barometer fall
ing to 1913 at Tatoosh Island by the
morning of the I'd, and the wind attaining
maximum velocity of sixty miles per
hour on the upper coast. This depression
continued to haunt the upper coast until
the 9Th, when there was clearing of the
storm conditions.
On the evening of the Sth a second dis
turbance appeared, advancing toward the
upper coast and had passed to Eastern
Washington by the evening of the 9Th,
and gave the heaviest rains to the Wash
1ngton coast of any disturbance during
the month. On the evening of the 10th a
disturbance developed in Southern Cali
Tornla that continued in that region for
several days and only disappeared en-
tirely by the morning of the 18th. On the
18th a storm advanced toward the upper
coast and gave general rains to Oregon,
Washington and the northern portion of
Northern California, and passed east
ward to Manitoba by the 18th.
On the 18th another disturbance mani
tested itself north of Washington by rains
and high winds on the Washington
Coast, and this passed eastward by the
evening of the 10Th. On the 26th a dis
tnrbance passed eastward north OF
Washington. On the 28th a storm adj
vanced toward British Columbia from
The ocean that developed into one of the
most severe and protracted storms of the
month by the Both, giving general rains
10 Washington, Oregon and Northern
California and snow to the mountain
regions Of those sections.
Foggy weather occurred on fourteen
days during the month on the Northern
California, Oregon and Washington
coasts.
Precipitation fell on every day during
the month in Washington; on twenty
seven days in Oregon; on fourteen days
IN Northern CALIFORNIA;; on six days in
Nevada, and on six days in Utah. Snow
was reported from Oregon on the 18th
and 18th; from Washington on the 10th,
and Nevada on the 10th, 18th and 10th.
High winds occurred on fifteen days
on the Washington Coast; eight days on
the Oregon Coast; three days on the
day the 26th) in Nevada
killing trosts occurred on the morning
of the 7th i'll Southern Nevada and South
eastern California.
TEMPERATURE.
The weather averaged warmer than
usual in November in all districts west
Of the Rockies. In Washington and
Oregon the monthly mean temperature
ranged from 80 to 90 above the normal,
except at Baker City, where it was but Il
above. In California 1t was from 2 to 60
above, being II degrees above in North
ern California. In Nevada, Utah and
Arizona it was from 60 to 70 above.s
From unofficial records on railroad
lines, and from the records of volunteer
observers, extreme maximum tempera-
lures We're recorded as follows in South
ern California: November 4th, 920 to 967;
9Th, So TO 1902, 9th, 1907; 9TH, SO, and from

PRECIPITATION.
No appreciable precipitation fell at
Carson City, KeeIer, Los Angeles, Yuma
or Tucson during November, 1891. San
Diego had 10 Of inch; Fresno, 20; San
Francisco, 80; Sacramento and Red Bluff,
so; Winnemucca, 10; Salt Lake City, go;
1toseburg, $40; Baker City, 1.30; Helena
80; Spokane, 1.50; Walla Walla, 1.60;
Portland, 80; Port Angeles, 60 and
Olympia, 1880. The precipitation was il
excess of the usual November fall in
aVestern Washington, at Baker City and
Helena; elsewhere there was general
deficiency, the most marked being for
Western and Northern California, San
Francisco and Red Bluff showing de-
6ciencies of 2.25 and 2.34, respectively.
Considering the seasonal falls to date,
the following deficiencies are computed
Tied Bluff, 422 inches; Salt Lake, 4.O6;
San Francisco, 2.S3; Spokane, 2.79; Sacra-
and Los Angeles, 1.88; San Diego, 1.45;
Yuma, 1873; Carson City, 1.27; Keeler, 10,
and Winnemucca, SO. The excesses are
as follows: Olympia, 5.66; Port Angeles,
q. .43; Baker City, l.34; Roseburg, 80, and

AVERAGE DECEMBER PRECIPITATION.
The section of California having the
greatest amount of precipitation in De-
cember lies lust west of the Sierra Nevada
(Northern Humboldt and Del Norte
Countess and that having the least lies
north of the San Bernardino range, east
ofeastern Uulare and Kern Counties The
eastern half of San Diego County also
usually receives less than an inch of rain
fall during the month.
Along the coast from Monterey Bay to
San Diego there is q general average OF
4 inches of rainfall, but north of Monte
yey Bay along the coast it averages from
to s inches, except off the point of
Cape Mendocino, in Humboldt County,
where it is slightly less than 4inches.
The deficiency of rainfall at the more
exposed points on the immediate coast is
doubtless due to the strong ascending
winds at such places.
On the Washington and Northern Ore
gon coasts there is an average of over 10
inches of rainfall in December, which at
some places, Neah Bay in particular,
reaches over Is inches. There is a record
Of over q inches of rain in December,
1853, at Neah Bay and nearly % inches at
Astoria, in 1867. In Eastern Washington
and Oregon, east of Cascade Range, the
December rains do not average more
than from 2 to inches.
The heavy condensation near the coast
lis due to the generally strong south
winds blowing into the low area storms
tnat advance toward the upper coast
over the Japan current, and also TO the
meeting of this wind current with that
coming down the straits, and to the two
ocean streams that wash the outlaying
peninsula of Washington.
