Icing??

[Krallu]

Hi!

I've read that in the weather information there is a figure that tells me at what height it is 0 degrees. Today 3000 feet for example.

And then it is icing conditions in the rain and clouds. What does that 3000 feet tell me. Is it safe to fly below 3000 feet where it is plus degrees even tough it is icing in the rain and clouds over me?

Thanks!
