What's the weather really like in Brindleton Bay?

I was creating a gift shop there in BB, and while my sim was at the store fixing things ( all in time about a week in game), it was thunderstorms with lightening alot, and alot of rain, she had to stop what she was doing many times to clean up the floor where it was striking outside her business ( she was getting it fixed up to resell it, she was a tycoon type or business renovator)
