It seems that an unseasonably warm February has prompted the trees to start their bloom cycles two weeks early, Jason Samenow and Kevin Ambrose explain in the Washington Post. "If we have some cold weather it will slow down the rest of the trees, which we expect to happen, so we should have cherry trees for the Cherry Blossom Festival". Records dating to 1921 show the earliest recorded peak bloom was 1990, when it came on March 15.
"Spring is springing. Flowering trees are starting to do their thing", Vietzke said.
The forecast is always subject to change depending on local weather conditions, the National Park Service noted.
This year's National Cherry Blossom Festival, which is timed to coincide with the blooming, will be held from March 20 to April 16.
