President Barack Obama opened a six-day European tour on Monday in Ireland, where he planned to celebrate his own Irish roots and give a boost to a nation grappling with the fallout from its financial collapse.

After an overnight flight from Washington, Air Force One touched down on Monday morning in a rainy and very windy Dublin. It was Ireland's worst storm in months, raising concerns about whether Obama's itinerary could go forward as planned.

But after a brief helicopter ride in gusty winds, the president and first lady Michelle Obama arrived without a hitch at their first stop: Dublin's Phoenix Park, the biggest urban park in Europe and home to the official residence of Ireland's longtime President Mary McAleese, who is nearing the end of her 14 years in office.

The Obamas greeted McAleese and her husband, Martin McAleese, outside the stately residence and headed inside exchanging pleasantries about the weather. President McAleese apologized for it, but Obama insisted he could feel the sun coming out. Inside, the Obamas signed a guest book and waved to TV cameras, before heading into a closed meeting.

Obama was then to plant an oak tree next to one planted by the queen of England in her visit last week, near a peace bell marking the 10th anniversary of the Good Friday accord.

Next up was a meeting with Ireland's taoiseach, or prime minister, and with U.S. embassy staff, and then the centerpiece of the Obamas' largely ceremonial one-day visit: a jaunt to Moneygall, the tiny village in County Offaly that is the ancestral homeland of Obama's great-great-great grandfather on his Kansas-born mother's side.

As the story goes, Falmouth Kearney, a shoemaker, left Moneygall for the United States in 1850 at the height of Ireland's Great Famine. Obama's roots in the town were discovered during the 2008 presidential campaign.

Residents in the village of about 350 have been eagerly anticipating Obama's arrival, applying fresh coats of paint to their homes, patching up the roads and hurriedly building a coffee shop called, what else? Obama Cafe.

White House aides say the president shares their excitement and may even raise a pint at a local pub and connect with a few distant relatives.

"It's certainly quite likely that in a town of that size that is so deeply rooted in that part of Ireland that there are people who share those ties," said Ben Rhodes, Obama's deputy national security adviser for strategic communications.

Obama was to wrap up his trip here with an open-air speech weather permitting at College Green, the same spot in the center of Dublin where President Bill Clinton drew a massive crowd for a speech during his 1995 trip to Ireland.

Obama's remarks will be part of a larger rally that includes musical performances and appearances by popular Irish actors and athletes. In keeping with the festive mood, Obama aides said the president's speech would not be political, instead focusing on the deep ties that bind the U.S. and Ireland.

"It's also a chance to talk about the enormous affinity, frankly, that the American people have for Ireland that's rooted in part in the huge population of Irish-Americans here," Rhodes told reporters before the president left Washington.

Obama arrived just days after Britain's Queen Elizabeth II visited the Emerald Isle, the first trip to Ireland by a British monarch in about 100 years.

The back-to-back visits have given the Irish a much-needed reason to celebrate as they struggle to climb out of the financial hole created by the collapse of the country's banks and housing market.

Gripped by debt, Ireland was forced to take a bailout from the European Union and International Monetary Fund in November that could total $100 billion. The rescue package came with stringent conditions that will lead the Irish to slash 25,000 jobs from the state payroll, leaving many in this country of 4.5 million with deep uncertainty about their financial future.

Heather Conley, a Europe expert at the Center for Strategic and International Studies, said she hopes Obama's visit includes ‘a moment of reflection to see the personal impact and toll’ the economic crisis has levied on Ireland and other countries in the region.

After spending the night in Dublin, Obama heads to London for a two-day state visit at the invitation of the queen. He'll then travel to Deauville, France, to meet with the heads of leading industrial nations, before ending his Europe trip with a visit to Poland, a strategically important Central European ally.

An overarching theme of Obama's trip his eighth to Europe since taking office will be to reassure the region that it still has a central role in U.S. foreign policy, even though Obama has put a premium on boosting U.S. relations with Asia and emerging markets elsewhere in the world.

The president is expected to emphasize the need for the U.S. and Europe to be in lockstep against the backdrop of sweeping unrest in the Middle East and North Africa, not only in the NATO-led bombing campaign in Libya, but also as financial backers for countries in the region, like Tunisia and Egypt, that are pressing forward with democratic transitions.
