Usually if we get a rain, it will rain hard for 3-5 minutes, maybe, but these are few and far between. Did that, rained hard for about 2 min., then a few minutes later, rained for maybe 3 min., so figured out that was it. Loud clap of thunder close by and it started raining, and kept raining. This went for about 15 min. then tapered off to just sprinkles.
Might not sound like much, but I think that was the hardest rain we have had in about the last 3-4 years. It usually goes either North or South of us, but not today. We really needed it as we are under an extreme drought. Can't remember the last time I saw water running in my garden.
