WASHINGTON — Inauguration Day is shaping up to be a cold one for Hawai'i son Barack Obama.

A temperature of 30 degrees is forecast for noon, with swearing-in ceremonies scheduled to begin at 11:30 a.m.

The wind-chill factor will make it feel more like 15 to 20 degrees, area weather forecasters said.

As of 6 a.m., hundreds of people who do not have inauguration tickets sprinted across the Capitol Mall, hoping to get the best spots to watch the inauguration from the unreserved public viewing area.

Trains headed toward the Capitol on the Metro transit system's blue line were running at full capacity as of 6:30 a.m., pausing to let passengers off at some stops but not allowing more passengers on board.

By 9:30 a.m., thousands of people had been waiting in line two to three hours on the Capitol Building grounds and patience was wearing thin.

People with tickets to the swearing-in ceremony were designated for color-coded areas, but confusion was rampant as they were told to stand in one line after another and some started cutting in line, angering those who had waited.

At 10:30 a.m., David Wilson, of McNeil Wilson Communications, and his wife, Carolyn Tanaka, were still making their way by foot to the site of the inauguration ceremony.

"Carolyn picked up a pair of earmuffs," Wilson said. "And I had to buy a hat and gloves. I haven't bought a hat and gloves since I was in the Navy 30 years ago."

The weather is so cold and things are so confusing that some Hawai'i visitors have turned around to either watch the swearing-in on TV or try again later.

That was the case for Andrew Agbayani, 19, of 'Aiea, who set out at 3:45 a.m., walked two miles, and got in a line at 4th and D streets at 4:45 a.m.

But when the gates opened at 7:30, he and his friend realized they were in a line for the inaugural parade.

"It was pretty hectic down there," he said. "But I don't blame them because it's a real confusing time."

Agbayani went back to his hotel, but says he plans to try again later. He was wearing three or four layers of clothes with hand warmers and earmuffs, but said it was still freezing.

"Even though I had everything on, it was still cold."
