Matches getting cancelled due to rain?

I have been doing local steel matches for the last year or so and finally was going to do a USPSA match today.

I talked to the match director yesterday and the day before and he said there might be rain. My response was “I’m not afraid to get wet”.

I get to the match this morning at a range I’ve never been to and was told that match was cancelled due to rain, absolutely no chance of lightening.

Is this normal for a USPSA style match to get cancelled due to rain? I am not mad. The match director emailed everyone at 630 this morning to tell us it was cancelled, my bad for not checking.
