Could This Be Considered a Jumpscare?

[Zaffre]

I'm working on my first custom story, and there's a section called the Flooded Archives. In it is a room. In this room, you find a diary page from a little girl. After you pick it up, you hear a splash outside and a bar falling into place, with the text "You hear something being thrown into the water....". When you go to open the door, it breaks and a Lurker rushes through. Earlier on, you hear a Lurker under your feet and a note says that the Lurker shouldn't be encountered unless the Archives have flooded with high tide, because the sea level has risen since the mansion was built.

Could the door being broken down be considered a jumpscare? I added an early warning (the door being barred and the splash outside) and I want to have minimal jumpscares in my story. Thanks in advance.
