Road crews are preparing for a rare spring snow with forecasts calling for accumulations in Washington, central Maryland and east to the Delaware shore.

Snow is expected to fall early Sunday across the area. It may turn to rain later in the morning and Sunday afternoon.

In Washington, the city’s snow team is preparing to deploy about 160 plows by 2 a.m. to handle up to two inches of snow. Officials are asking residents to treat their sidewalks before they go to bed Saturday.

The forecast led organizers of the National Cherry Blossom Festival to postpone the annual kite festival on Sunday. They plan to announce a new date for the event on Monday.

In Delaware, forecasters say driving may be hazardous from Dover to the south.
