What does this percentage sign stand for?

@Suty “Because of possible uncertainties, we thus indicate two forecast-probabilities in our forecast information:
Predictability: The calculated probability of occurrence of the forecasted weather for the entire day and for all weather variables.
Precipitation probability: The probability of the occurrence of precipitations.”

Where can I find precipitation probability in the forecast panel? I can’t locate it, and only Predictability is shown.

Does this diagram mean there are no clouds in the sky within the red box area?

@Gkikas-LGPZ But the mountain stands at an altitude of 2,303 meters. If the cloud top is below this elevation, does that mean there will be a sea of clouds? Where can I check the cloud top height?

How to determine whether there will be sea of clouds on a specific mountain at a given time?
For example, this mountain has an elevation of 2,303 meters. Will there be sea of clouds during the time window framed in red?

@Suty Okk,thank you.

@Suty Thank you very much for your explanation, I understand now. By the way, which one is more accurate for hiking and mountain trekking, ECMWF or meteoblue AI?
