Larry has replaced several rain gauges. It's possible he'll have to replace more. But this winter he's been putting one-half inch alcohol in it. Night before last we got ice. Yesterday we had snow. Today he brought the rain gauge inside so the outside would thaw enough to read the accumulation of precipitation.
It requires paying attention and adding alcohol when the temperature is low enough to freeze the water inside the rain gauge. With the alcohol, it doesn't freeze and crack the plastic gauge.
