On February 9, 1870, President Ulysses S. Grant signed the law that brought the Weather Bureau, today’s National Weather Service, into existence. The law, the product of a resolution passed by the United States Congress, made the Secretary of War and the military responsible for “taking meteorological observations” and “giving notice…of the approach and force of storms” on lakes and coasts. The U.S. Army’s Signal Corps undertook this mission, and by November trained men were reporting on the weather from 25 stations across the country.
While early weather reporting was relatively unscientific by today’s standards, widespread use of the telegraph beginning in the early 1860s made it much easier to quickly gather information about the weather from many different points at the same time. Particularly in the late 19th and early 20th centuries, meteorology began to take shape as a developed field, and the American Meteorological Society was established in 1920. The Weather Bureau became a civilian institution in 1890 with its move to the Department of Agriculture, and its increasingly important role in aviation helped spur another move to the Department of Commerce in 1940.

Today, the National Weather Service’s duties have expanded far beyond the original charges of observation and limited forecasting. Because of the many advances in technology over the past half-century, the NWS is able to predict a wide variety of conditions such as floods, hurricanes, fire weather, and climate with increased accuracy. Its many services and reports are indispensable to the public, but also to the military and other government groups.
As a constant part of our daily lives and the source of many natural disasters, weather forms a significant component of many of the collections available through Opening History. In particular, the Hurricane Katrina Oral History Project through the Louisiana State Museum offers invaluable information about the hurricane and its effects on the lives of those who experienced it. The Mississippi River Flood Album of 1927 from the LOUISiana Digital Library, as well as the 1936 Gainesville Tornado collection from the Digital Library of Georgia, also offer images of two major natural disasters of the past century.
