Broken/ragged layer "fractostratus" is a broken stratus layer
Describe flying into a stratus cloud.
Low visibility but not much if any turbulence
Describe flying in cumulus clouds.
Bumpy AF but not really that dangerous unless there is a lot of vertical growth which is a big
sign of a thunderstorm.
