Niagara Falls will glow blue tonight to commemorate the newest addition to the British royal family.

The illumination board will light the falls for the first 15 minutes of every hour from 9 to 11 p.m.

This is part of a long tradition, says the Niagara Parks Commission.

The falls were also illuminated blue when Prince George was born in July 2013, and pink when Princess Charlotte was born in May 2015.

The Niagara Falls Illumination Board has lit up the falls since 1925.

Prince William, the Duke of Cambridge, and his wife Catherine had a baby boy Monday. Their third baby weighed eight pounds, seven ounces and doesn't have a name yet.
