Severe turbulence reports Just tell you where and what altitude it happened and sometimes type of aircraft reporting. Other than avoiding being in that exact same spot it may be difficult or impossible to know exactly where it extends vertically and horizontally so securing the passengers and crew is imperitive. You may find changing course or altitude will avoid it but maybe not.
I found making another check with the FA's to make sure everyone complied is also very important. The airliner in front of me into Anchorage one night had three of their FA's go to the hospital. It took a 2nd call from me when I heard them not in their seats to sit them down.
