With our storms, you need to worry more about the 50-70MPH gust front that precedes the rain. If you look at the bottom edge of the second image, you'll see the dust wall on the ground that indicates the outflow.
I have to be on the ground before that hits, or I risk losing the drone entirely because it'll be blown into the next county. Almost did that on Sunday, and barely made it to land about 20 feet downwind of my launch point because the battery was *gone* by then.
I started my descent at about 1200 feet upwind and 400 feet up, and got blown downwind *fast*. Had to fight to come back about 200 feet upwind, or I would have had to do some climbing to retrieve it.
