Frigid temperatures could spell disaster for Washington's cherry blossoms.

FOX's Rachel Sutherland reports from Washington:

The cherry trees, a gift from Japan, were supposed to hit full bloom this weekend, but a blast of cold air is threatening the fragile blossoms. Mike Litterst with the National Park Service says 90-percent of this year's blossoms could be destroyed:

(Litterst) "We had such a warm, mild winter that brought the blossoms out so early and now we've got this late cold snap, it's really unprecedented."

The trees themselves are fine. They can withstand the cold, and the pink petals will return next year. This year's National Cherry Blossom Festival will carry on as usual.
