The weather in March will be the most critical factor for the trees' blooming period, he said.
About 70 percent of the trees around the Tidal Basin must be blossoming with pink and white flowers for the park service to declare peak bloom. Tree workers will be looking for the first sign of green buds, monitoring the weather forecast and reviewing historical records to update Perry's prediction because the projection is not an exact science, he said.
"The colder it is, the slower the process will be," he said. But there hasn't been any significant damage from the recent snow and ice, he said.
"The buds are naturally protected within the trees during the winter," Perry said. "That's a dormant phase for the development of the trees."
Perry made the flourishing prediction as organizers announced plans Tuesday for this year's National Cherry Blossom Festival, one of the nation's biggest springtime parties. It's scheduled to run from March 20-April 13 with events permeating around the city to celebrate the trees and Japanese culture. About 1.5 million people enjoyed the pink and white blooms last year.
This year marks the 102nd anniversary of the gift of the cherry blossom trees from Japan as a symbol of friendship with the United States.
This year's festival includes a fitness theme with free exercise sessions planned around the city's monuments. There is also a new water shuttle service to the Tidal Basin from the Georgetown waterfront, a new hop-on, hop-off bus tour and a Japanese film festival for the first time.
Washington's restaurants plan special menus, city buildings will be lit in a dazzling pink and hotels are offering more specials for visitors this year, organizers said. Some signature events associated with the cherry blossoms include a Japanese street festival, a kite festival and a parade on Constitution Avenue.
