looking at weewx/drivers/acurite.py it seems the max is 100 inches. line
335 says bits 24-25 are for rain:
24-25: rain (r[24]*256 + r[25]) * 0.254 mm
two bytes hold 64k * .254 = 16646 mm = 16.6 meters = 655 inches. so either
the counter wraps around at 655 inches or it locks up and stops working and
you have to buy a console or find a hack at 100 inches.
not sure it will ever rain that much here. there is a chronic drought.
