Forecasts as of Dec. 16 called for more seasonably normal temperatures for at least the short term.
At first, growers and officials thought that mandarins were damaged by the freezes but not navels. But after the night of Dec. 8-9, the sixth night of the cold snap, California Citrus Mutual announced that navels were likely damaged, too.
During the snap, official and growers also expressed concerns about the high costs of frost prevention and potential breakdowns of heavily-used wind machines.
