Default False readings - Garmin XM weather

I am very perplexed with the new Garmin Weather. It has been accurate for rain clouds within 50 feet until last week. I have 30 hours on the module.

It happened last week in the keys and again today. At 8 am there was not a cloud in the sky and I got the pic below. The area that I note as green is a large squall – this screen set at 2 miles. You can clearly see my loc within the rain. It never rained today in South Florida. Further it shows a thunderstorm too (yellow) a bit west.

I can think of no settings that are causing this except the recent update as it never happened before this… Ideas?

Glenn,

I have the same unit and have found it to be very accurate. Many times I have been at Sands Cut and have had boats head for shore left and right due to an approaching storm. But with XM Weather I have been able to see exactly where the cell was and what direction it was moving on XM Weather and make my decision to stay because the storm was going to miss us. So far it has been extemely accurate down to each break in the cloud cover. This sounds like an anomoly.

That is very interesting. I havent come across this yet but I will make a call to WSI which is the radar provided to XM & SIRIUS and see what they say. Maybe that radar tower was having work done on it.. tuning?

Because I am a bay fisherman, I chose to get my doplar through my blackberry.

One thing I will note is that even Weatherunderground.com radar and weather.com radars both have bad echos at times. Could just be bad feed back from the ground doplar system.

Glen - don't you also have genuine radar on your boat. If so, did it show anything. I know my radar will show the lightest rain shower as a strong echo if I have the gain turned up. I don't know what parameters XM use on their weather radar - maybe they had their gain turned up too high.

radar and crew eyesight showed nothing in the sky (not even cluds) in all directions...

I would be more concerned that you just gave the entire world the locations of the infamous "Edge 1" and "Deep Yellowtail" spots.
