Formerly the Weather Bureau-Army-Navy Severe Weather Unit, the recently-renamed Severe Local Storms Warning Service (SELS) relocates from Washington D.C. to Kansas City, Missouri. The new location puts the SELS closer to the American midwest, a hotbed of severe weather during the spring months, as well as placing it in close proximity to a major telecommunications hub (at this point, the SELS is reliant almost entirely on teletype transmissions). Additionally, precise definitions of what constitutes a severe thunderstorm (winds in excess of 50mph, wind gusts in excess of 75mph, and hail in excess of an inch in diameter) are established, as well as a concerted effort to target its weather bulletins to more precise geographic regions.
The first Godzilla movie, Gojira, debuts in Japan. Directed by Ishiro Honda and starring Akira Takarada, Momoko Kochi and Akihiko Hirata, the film is intended to be an allegory to the ravages of the atomic bomb rather than the beginning of a franchise (though the door is clearly left open to a sequel by dialogue at the close of the movie). The franchise proper will not begin until the first sequel five years later. In the meantime, an American dub of the movie attracts worldwide attention to Gojira, eventually rechristening the character Godzilla for much of the world.
