During warm winters & winters with rain-on-snow, snow melts/refreezes creating ice layers hard for reindeer to dig through to fodder. Comparing weather data with reindeer births in Scandinavia shows birth rates drop after winters with lots of rain-on-snow events.

When rain falls on snow it creates a layer of ice that impedes feeding, which in turn has reduced herds’ birthrates

Though California has been quite (rain) wet so far this water yr, its worth noting that it was dry enough in the south 2/3 of state last yr so that current odds of making up the last-yr-plus-this-yr deficits by end of this water yr are small except in northern parts.
