Two of the controllers and three of the pilots involved in a runway incursion at hou describe their views of how the incident unfolded. The LR35 was cleared to cross runway's 12L and 12R and a B737 was cleared to takeoff on runway 12R before the LR35 was clear. Light rain and low visibility may have been a factor.

Narrative:

Aircraft Y had just landed and was taxiing on taxiway kilo to the ramp. Coordination had been made for a crossing of the parallel runways. The aircraft had just crossed runway 12L and was entering runway 12r when I thought I heard the local controller clear an aircraft for departure. (I scanned to see where my aircraft was and saw aircraft X starting a roll down the runway.) I told the local controller that my plane was still crossing and then told the pilot to expedite his taxi. The pilot informed me he had the plane in sight. The pilot was taxiing unusually slow because of rain and slippery surfaces. He took much longer than usual to cross.the long delays the aircraft were receiving waiting for reroutes was a factor. Pilots were trying to get to their destinations and they were at runways waiting for reroutes. It became difficult to get the reroutes and pilots were getting frustrated. I would recommend that more people need to be working center reroute position on forecasted weather days. Too many changes and too few people led to an excessive delay for pilots.
