The National Park Service has announced that peak bloom this year for the signature cherry blossom trees of Washington, D.C., will begin between March 28 and 31.

Peak bloom is reached when at least 70% of the Yoshino cherry blossoms are open. If the projections are correct, it will happen toward the midpoint of the National Cherry Blossom Festival, which spans from March 20 through April 13 this year. Once the trees hit peak bloom, they'll stay that way for about 10 days, according to FOX5 D.C.

The National Park Service predicts peak bloom will be between March 28 and 31, but depending on the weather, blossoms can be seen both before and after those dates.
