Last night we had a thunderstorm and this morning, one entire circuit
in our box is dead.

The breaker was not tripped. I even turned it off and on again but
that did nothing.

One other breaker was off, but that only goes to the indoor
tub\jacuzzi which is not working so I MAY have turned it off myself a
while ago, but I don't think so. I turned that back on.

The dead circuit is for the garage door openers and some lights and
outlets in the upstairs bathrooms for the most part.

Any ideas of what may have happened?

Yes it could be the circuit breaker. Could also be a bad connection on the
circuit.

If there's not 120 on the hot side of the circuit breaker, the circuit
breaker is the culprit.
