They might... If it were me I would pull them inside if I could. They say once you put them outside never bring them back in but I think 5 day old sprouts are fine when it comes to that. If they are drenched I would put them some place to dry out. You don't want root rot or bugs to come about. I have a friend who is growing outdoors and he has left them out thru all the heavy rains so far this summer and the last time I saw them it seemed their growth was stunting... I figure from overwatering. They can just as easily get naturally overwatered and die... Just like crops do.
