This is actually something that happens fairly regularly. Sometimes they even rotate the space station so the smallest frontal area is facing the debris cloud.
Sounds stressful...Wake up, shower, dress, then have breakfast with your ISS colleagues, while keeping up with the latest edition of the Orbital Debris News!
Slightly tongue in cheek, but the astronauts on board are not going to be the ones doing the mission planning around debris checks - that will be coordinated from the ground.
