We're in it right now. We're trying to time a ride so that we get soaked! We work Mon-Fri. The ground needs to become completely saturated before subsequent showers create ponds and streams and flooded washes. I think we're finally getting there. Rained hard in our local mountain range yet no flowing water. A couple more downpours and we'll be set. But you still have to hit it within a few hours otherwise it soaks into ground, moves elsewhere to lower elevation or dries up completely.
It's cloudy, but rain hits like a tornado. Hitting one small section and completely missing an area adjacent. Then we have waters that come rushing when the storm happened 15 miles away.
Soon...
