This Date in Weather History

1941 - Only two women were employed by the Weather Bureau. By 1945, more than 900 women are employed by the Weather Bureau as observers and forecasters, as a result of filling positions of men during World War II. Eleven days after Pearl Harbor, the Army requested that all weather broadcasts be discontinued. The fear was that the enemy would use this information to plan an attack on the United States.
