They will be fine and will recover on their own. If it doesn't rain much, I'm sure they will appreciate a little water. They will likely send up a few replacement fronds this year and come back full force next year.

They should recover on their own, maybe not fully this year, if new growth has already emerged. Check the plants to be sure that the soil around the roots is firm and be patient. I have found that they are tough plants and will survive almost anything. Even with the roots enclosed in a plastic bag, sitting on my rear driveway(plant storage area) for several years, they still emerge every spring!
