New York City was awash in green and Irish pride as throngs celebrated at the annual parade.
Sunday's parade marks the 194th edition of the event, where tens of thousands of people will gather to watch the procession at noon as it kicks off at the corner of Ste-Catherine and Fort streets.
Irish eyes will be smiling Friday as Peconic's Naomi Cichanowicz, 12, Irish step dances her way down Fifth Avenue during the New York City St. Patrick's Day Parade.
Over the next 35 years, Irish patriotism among American immigrants flourished, prompting the rise of so-called "Irish Aid" societies like the Friendly Sons of Saint Patrick and the Hibernian Society.
Even though St Patrick's falls on a Friday this year, the New York Archdiocese says Catholics don't have to abstain from eating meat. "It's a once in a lifetime opportunity". He paused to greet Cardinal Timothy Dolan outside St. Patrick's Cathedral, which was adorned with the American and Irish flags; a special Mass was held there before the parade stepped off. "He's always wanted to do it".
Mayor Bill de Blasio will march in the parade, which he had boycotted until previous year, when gay and lesbian groups were allowed to participate.
In a first, the parade will march past the home of the sitting president - Trump Tower.
