That means that last radar data in this area are outdated. During the 1h loop, radar data are received by Windy at regular time intervals. If last data are not received in time, the data of the previous interval are displayed but hatched.
Interesting..... I just tried cycling the mute switch back on then back off again, and the sound started! When my phone goes to sleep and I unlock it again, I have to toggle the mute yet again to get the sound again.
Maybe this is a bug?
@idefix37 I'm unable to reproduce the 3 fold discrepancy I was seeing last week. But here are some screenshots showing a 2x descrepancy for the same location, which is still pretty significant, especially for a forecast for the current time. This is a pretty big difference in visibility when hiking in the mountains.
I'm not exactly sure what it would mean for the grib file to be sent at lower resolution. It was previously mentioned as an explanation for why the interpolated value would be different at different zoom levels. Something seems to be more course at higher zoom levels.
