I am talking about the warning that replaces the forecast icons in the bottom 1/4 of the screen.
I can't say that I have noticed this. I would suspect it's static on the SD feed due to the limited space on the screen. It might remain visible all the time. This may also be dependent on the warning type, this is just a guess though. I'll have to check it out next time there is some scary weather coming.
Up to the last few weeks it use to scroll when a weather warning or watch is issued for Winnipeg and area.
Currently when one is issued you should see more than Weather warning issued for : and nothing else comes up.
I wonder if its a problem with the data from Pelmorex (weather network data provider) hanging as they are inserting it to the MTS feed .
