Explored gate -gate appearing

By tperk4369, in Arkham Horror Second Edition

A character is standing on a gate that they have explored. They want to seal the gate with clue tokens, however the have failed their lore tests and must wait until next turn to try again. If during the methos phase their location is where a gate opens does this cause a monster surge? Does the terror track go up?

thanks for the assist.

A monster surge occurs. But the terror track does not go up unless, if the monster limit is surpassed, the monster surge causes the monsters in the outskirts limit to also be surpassed.
