MAYS METEOROLOGY.
The Month Made Cool by Frequent
Northwest Storms.
Five Inches of Rainfall at Crescent
City in One Day-Local storms
In Various Places.

Lieutenant John p. Finley, the officer
IN charge of the Signal Service Bureau
Tor the Pacific Coast, in his report for the
month of May states that it was distin-
gulshed by abnormally low barometric
pressure in the Pacific Coast States espe-
cially the southern portion, which condi-
ton has resulted from the movement
eastward of a large number of cyclonic
areas over British Columbia, and their
extension southwestward after crossing
the mountains AS far as can be ascer-
tanned from the records at hand, seven Of
these areas entered the Pacific Coast near
Vancouver's Island. The influence of
these disturbances was very decided upon
the weather of the eastern and southern
portions Of the Pacific Coast States, even
after the storm centers had moved east
ward into Montana and Dakota.
AS the result of such influences rapid
and sudden changes in temperature have
occurred, attended by heavy cloud for
nation, rain, snow and severe local
storms. While the occurrence of rain
has been beneficial in many instances to
agricultural and horticultural interests,
yet considerable damage has resulted
from excessive precipitation, high winds
and low temperatures. 1t is believed,
however, that less damage has resulted in
California than would have followed the
prevalence of hot northerly winds.
RAINFALL.
Owing 10 the frequency of storm move
ments over British Columbia, as above
explained, there has been an excess of
precipitation in the northern part of Cali
Oregon, the amount varying from 0.63
inches at San Francisco TO 80 inches at
Winnemucca. There has also been an
excess in eastern Arizona, which is shown
Dy an increase of Lib inches above the
normal at Fort Grant. Floods were re-
ported from Eastern Arizona and New
Mexico, causing considerable damage.
Floods were reported from parts of
western Nevada. The excess at Rose
burg, Or, reached 2.2l inches.
The area of deficient rainfall includes
California south of San Francisco, eastern
Arizona. southern Nevada, northern
Oregon and Washington. The deficiency
was most marked in the San Joaquin
Valley, minus LII inches at Fresno and
in eastern Washington, minus LIS
inches at Walla Walla. The precipita-
ton attending the storm areas from the
Pacific appears to have increased with
their progress eastward when their south
west quadrants affected the South Pacific
region. Rain fell on rs days in Califor-
mia. snow on days; on a days in Ne
vada, snow on Z days; on days in Ari-
iona; on % days in Oregon, snow on ,
days; ON p days IN Washington, snow
on 3 days. The greatest rainfall in a
hours occurred at Crescent City, CAL,
BIB inches, on the 4th and 5th; LAC inches
