It's something you rarely see - a pre-taped weather forecast that goes completely off the rails.
On Sunday night's CBC local news at 11 PM, the anchor threw to Saphia Khambalia, the Weather Network host, who does the forecast for the Corp. The intro ran, on came Khamballa and started into her spiel about what to expect on Monday, complete with the radar map.
Everything was fine for about the first 30 secs. when she suddenly tripped over the words "moisture laden southerly...." stopped talking, put down the clicker and said, "I'm going to do it again. Sorry." She then reversed the map on the screen, adjusted her wardrobe, moved the poppy on her dress and brushed away her hair.
After that, she said, "OK, ready...", then froze on the set, apparently waiting for the cue for the recording to start again. Viewers who didn't know the weather is pre-taped (dangerous considering a tornado warning was issued just moments before that by Environment Canada for the Niagara Region) found out, but they also never got the forecast at all.
After several very uncomfortable moments, they cut back to the anchor, who said,"We'll get back to Saphia in just a few moments," before moving on to another story. But they never did.
It's the kind of mess you rarely see and why I generally recommend you do everything live if possible. If they roll the wrong take, it can be a disaster on air. And this was definitely a bad spell of weather.
