Hurricane Arthur was upgraded to a Category 1 storm Thursday, with high winds, warnings of possible storm surges and — just generally — some really lousy timing.

Arthur, the first named storm of the Atlantic season, was gaining strength as it moved toward land — spoiling Fourth of July plans and beach days along the East Coast.

“Don’t put your stupid hat on,” North Carolina Gov. Pat McCrory said at a Wednesday news conference, according to WWAC. “Usually most injuries occur right before a storm or right after a storm, so especially on the coastal area, we want to make sure people don’t try out the great waves before the storm comes, even though they are good waves. We don’t want you to go into the ocean.”

Tourists and residents were evacuating in the Outer Banks, including vacationers like Susan Holbrook, an Illinois woman who told the Virginian-Pilot that she and her husband were moving inland. “It’s Mother Nature,” Holbrook said. “You can’t do anything about it.”

Among the Arthur-related holiday changes:

Even the annual Boston Pops Fireworks Spectacular wasn’t spared; the celebration was moved up a day because of Arthur, with fireworks now scheduled for Thursday night.
