Weather Service Will STOP SHOUTING the FORECAST
April 12, 216
Since forever the National Weather Service has issued their forecasts IN ALL CAPS. This was because the teletype, first patented in 1846, that they used in the early years could only handle capital letters. And being a government creature of habit all of their systems were configured for decades to that teletype standard. But in recent years the agency has been upgrading their equipment to a technology more advanced than the teletype.

With the use of the internet, most people now interpret ALL CAPS as yelling or screaming, or at least an indication that the content is extremely important. If everything you type is SCREAMED, that limits opportunities for escalation of importance.
