An alerted U.S. carrier counterstroke at Pearl Harbor

What should an alerted U.S. carrier force outside Pearl Harbor do once the Japanese attack begins?

Launch strikes toward the direction from which the Japanese aircraft came and use the raid's approach route to find the carrier force.

The scenario gives the United States Navy warning of the likely attack date and stations two carriers with escorts outside Pearl Harbor. Once word arrives that the base has been hit, the immediate response is to launch strikes along the direction from which the Japanese aircraft approached. The returning raid becomes a clue to the location of its carrier force. No particular battle result is promised, but prior warning and a ready carrier force could turn strategic surprise into an immediate counterstroke.
