Extra.tropica.1cyclones a,nd gales.-January 1938 was a stormy month on the North Pacific, with gales of practi- cally daily occurrence on some part of t'he ocean, and winds of the higher forces, 11 to 12, reported on the 3d, 5th) 9th, IObh, and 26th to 2Sth in middle and high htitudes, to the westward of the 165th of west . During the 2d to 5t,h of the monbh w-iclely scattered gales were, encountered between about 140' JV. and the const of Japan. The. principal storm area of the period, however, lay to the westward of the , with re,ported gales occurring between latit'udes 30' and 45' N. On t.he 2d the ce,nter of a cyclone of sonie magnitude lay east of the island of Hokushu, whe,nc,eit moved east- northeastwnrd, and on the 6th crossed the central Aleutians. The heaviest winds reported in connection with the storm occurred fa.r south of the center. The Jn.panese motorship Sm Pedro Mwu, nea.r 34' N., 145' E., on the 3d, met a west hurricane while the storm center lay nea.r 45' N., 160' E., and the Brit,ish motorship Silverbelle enc.ountered a like wind near 37' N., 165 E., while the c.e.nter was close to 46' N., 150'. On the 7th anot8he.rstorm lay to the immediate east of Japan.

During the 9th and 10th the cyclone area extended over two-thirds or more of the width of the oce.an in high , and caused scattered 31 gales of force 9 to 10 as far to the eastward along the 0,12 28 northern routes as about longitude 150' W.

By the 15th and 28 2 16th the gale region had estended w-ell toward t,he coast of the United States, as indicated by the report of the Nom.-Data based on 1 daily observation only, except those for Juneau, Tatoosh motorship Saparoea which encountered a force-10 wind Island, San Francisco, and .Honolulu, which are based on 2 observations.
