A meaningless phrase that prefaces relevant information. It is basically unnecessary if not redundant, as one is engaged in the very act of “advising” when issuing a warning, imparting knowledge, or giving advice. “Please be advised” is used excessively by people in law enforcement and sometimes by those who became serious about life at a very late age, and now maintain blogs that purport to warn the public about what is largely one-sided, uninteresting crap.
Ryan: Officer Murphy, please be advised that our suspect is driving a Jeep.

Murphy: Ryan, the fact that you’re advising me is understood in the information you have just given to me. Saying “please be advised” is an unnecessary redundancy that pollutes our radio communication.

Ryan: Ten-four.
