Citing cooler than forecast temperatures this week, the National Park Service last evening (March 15) revised their peak bloom forecast again. They now expect the start of the peak bloom period to be March 23-24. And they’re putting an emphasis on this being the beginning of the period.
For photos of how the trees were looking as of yesterday, take a look at the March 15 Cherry Blossom Watch update.

They also judged that 70 percent of the trees had reached the “extension of florets” stage on March 15.

If you'd like to help support the care and upkeep of the cherry trees around the Tidal Basin, the Trust for The National Mall has launched an Endow a Cherry Tree Campaign. Donations go to the official Cherry Tree Endowment, which will give the National Park Service additional resources to fund the care, maintenance, and possible replacement of the cherry trees.

The Trust is dedicated to marshaling private support for maintaining and improving the history National Mall area. I'm not affiliated with the Trust--just an admirer of their efforts.
