The all-caps format of NWS bulletins emerged from the limits of the teletype keyboard, together with standards set by the World Meteorological Organization designed to accommodate nations with widely varying technological capabilities. No capital letters were allowed, and the only punctuation permitted was periods (.), ellipses (…), forward slashes (/), dashes (—), and pluses (+). These conventions went largely unseen by the public until the NWS website was established in the 1990s. Before that point, NWS text products were reformatted by newspapers or read aloud on TV and radio, including NOAA Weather Radio.

The best one in history has to be this one. It was so out of sorts, it has its own WIKI page.
