Why do worms come out in rain?

It has been raining a lot here and worms are scattered across roads and sidewalks. They only seem to do this when it rains. All feed back appreciated thanks!!

Worms get oxygen through their skin, which has mucus-secreting cells, so it has to stay moist. If they came out in the sun their skin would dry up and they would die. In the rain they can navigate above ground much more easily and they won't dry out.
