Freezing Rain Advisory?

The weather service continues to confuse me. Freezing drizzle started around 10:00 this morning, yet they waited until after 1:00 to issue a freezing rain advisory. I don't know about the rest of the advisory area, but there hasn't been any freezing drizzle here since around noon. Seems to me like the advisory came a few hours too late. And why is it a freezing "rain" advisory when there is only freezing "drizzle"? Does a freezing drizzle advisory not exist anymore?
