Put it in a Ziploc bag and freeze it with the date. This is history.

What a rude and insensitive comment. The suggestion that one could simply "wipe up" the rain with a towel is not only incredibly rude but dangerously ill-informed. You are completely ignoring the basic physics of saturation and surface area, as a standard towel would be rendered useless within seconds of a legitimate downpour. Offering such flippant and technically impossible advice is incredibly tone deaf. It is deeply condescending to mock another user's concerns with a "solution" that wouldn't even manage a fraction of a millimeter of accumulation. Unbelievable.

Better than nothing!

By August the effect is probably done, but there is no doubt a low snow pack extends the length of fire season by allowing it to start earlier.
