The National Weather Service announced Monday that it will no longer send updates in all capital letters, and in doing so, it will not appear to be screaming at readers.

Spokeswoman Susan Buchanan said caps were used from the time the agency sent forecasts by telegraph in 1849.

In an increasingly digital and social media focused-age, all caps has been interpreted as shouting.

The weather service made an attempt to move away from all caps 20 years ago, but the older equipment could not understand lower-case letters.

"People are accustomed to reading forecasts in upper-case letters, and seeing mixed-case use might seem strange at first," NWS meteorologist Art Thomas said in a statement to the National Oceanic and Atmospheric Administration.

"It seemed strange to me until I got used to it over the course of testing the new system, but now it seems so normal," he said.

Buchanan said the agency will still have the option to send messages in all caps, such as emergency alerts.

The agency will begin using mixed case May 11.
