Can I remove a car battery when it's raining?

My car won’t start. I think the battery is dead. Of course, I would wait for the rain to stop, but there’s time-sensitivity here, as I have to get this done before shops close for Christmas. I have a trip planned the morning of 12/26. It’s supposed to rain most of tomorrow, 12/24. Hence my question… if it’s raining, will I get a shock or anything if I remove the old battery? Any difference between light rain and steadier rain?

(No, I don’t have opportunity for shelter, since the car is parked on the street and is not starting.) Thanks for any suggestions.

As you might be able to tell, I’m not real good with cars.
