That Canadian trend on weather surprises me because people need actual temps. However, when I want to brag to my wife, it's great to tell her it feels like 110 I've been out working in. But I can make that up!
TV and radio news folk do talk fast and have a sense of urgency. I think it keeps an audience more riveted. I also think they've gotten more hyper.
When Hurricane David hit our county in Florida in 1979, my Dad had a heart attack. He was 10 miles inland so flooding was unlikely, though wind could be bad. He'd always said when we lived on the beach that a direct hit at high tide would take us out. Turned out, he was right many years later. But David turned out not so bad.
Now I am old. And noticing that I get much more anxious when something like "snowmaggeden" is on the way. I decided during the news buildup for it last week that I would avoid TV and radio weather and just use the print report online.
