"Shout in a whisper" verb

What is the verb that means something close to shout and call out to sb but quieter? I mean when you shout something to a person that is far away but you don't want anyone else to hear so you hush your voice (but still you shout). I've searched for "shouted in a whisper" but it somehow sounds strange to me.

There is a verb and it is - ta-da! - whisper-shout.

The act of screaming at someone without using any vowel sounds, so as to keep the volume of the scream down to a nominal level. Similar to the well known "SHHHH!" but it is actually a word or a group of words.

Often used in classroom or library settings, it can also be useful in churches or as a warning that someone unwelcome is approaching. [Urbandictionary]

It is not in canonical dictionaries but it is a clever coinage. You can find many examples in Google Books also.

Some examples:

"Shh!" Veronica looked into the kitchen and adjoining dining room. "Empty," she whispered. "They must be upstairs. Let's get going."

"No!" I whisper-shouted. "We've come this far. We've got to get some pictures!"

I have never heard nor read the term whisper-shout before today. I checked in Urban Dictionary, there is one definition and that has only eighteen upvotes against four downvotes. This tells me that the expression is not yet established. Chances are it won't be too soon either.
