What's the fiercest storm you've weathered?

Ironically enough, it would be a noon storm in Biloxi, MS USA. I was there with my exhusband and every noon a storm would come in for about 15 minutes than blow out from the gulf of mexico. One particular day, it rained so hard I couldn't see past my windshield and had to simply stop in the road, praying that nobody was stupid enough to drive in it. After a few minutes it passed but I will never forget that.
