What does it mean when one fllushes the toilet, the tank empties, the

one looks at it an hour later, almost all the water is gone from the
bowl?

Does this happen during high winds? The vent stack creates a vacuum
and sucks water out, is what I'm thinking.

I think it happens all the time, but only for the last 2 or 3 days. I
don't think the winds have been high much of the last 3 days. Thanks.
