Can DEF fluid be stored outside in the winter?

How cold is too cold for diesel?
Myth #2: Diesel engines won’t start in the winter. “Today’s technologies for cold-start are very effective,” Ciatti said. “Modern diesel engines start in cold weather with very little effort.” The problem is that diesel jells at low temperatures. Below about 40°F, certain hydrocarbons in diesel turn gelatinous.
