It may sound obvious but the secret to effective communications is to keep it nice and simple.
Things can get confused. Writing to a deadline while also trying to incorporate all the relevant info sometimes means that detail can obscure the message. Make sure the key points stay in focus.

You can expand on the details in the body of the story along with quotes using a 'bite-sized' technique.
