I hear you bruce! We had
enough trouble trying to cope with several days of heavy rain this fall, and they were each a day apart. (For the techies, over 5 days we got 13.8 mm, 2.9 mm, 19.9 mm, 0.3 mm and 21.8 mm = 58.7 mm. The ducks were happy, the
chickens not so much!)
It's not so much if you're used to coping with it, but it can cause flash floods and wet basements if the area isn't. However even if the storm is well beyond normal,
permaculture has a lot of solutions that can help you with observing what happens during this storm and make helpful plans to cope with the next one. Storms have been getting bigger and more frequent, so I not only hope you come through without major calamity, I hope you look for ideas of how to make it safer the next time.
