STEVE INSKEEP, HOST: Good morning. I'm Steve Inskeep. The National Weather Service will stop using all capital letters.</s>RENEE MONTAGNE, HOST: Steve, why are you shouting?</s>STEVE INSKEEP, HOST: Because that line was written in all caps.</s>RENEE MONTAGNE, HOST: Oh, what people take for shouting in a text message.</s>STEVE INSKEEP, HOST: Well, that's what we think now. But all caps used to be the way the Weather Service wrote on teletype machines. Now that the Internet makes all caps seem rude, weather service bulletins are changing at last - calming down, we are told, except in the case of emergencies.</s>RENEE MONTAGNE, HOST: It's MORNING EDITION.</s>STEVE INSKEEP, HOST: Oh, sorry, Renee, that should have been lowercase.
In the days of teletype, the forecast came out in all capital letters. The Internet has changed things, and now all caps means yelling. The mixed-case letters appear on forecasts beginning May 11.
