[Updated 11:00 p.m.]¬†New Jersey Governor Chris Christie said cats and dogs would be welcome at the emergency shelters set up for people fleeing the storm.
‚ÄúIf you have your pet bring them with you. ‚Ä¶ No one should be staying in their homes in an endangered area because they feel like they can't bring their pets with them," Christie said.
Mark Lavorgna, a mayoral spokesman, confirmed that pets are allowed in the 91 emergency evacuation shelters set up in preparation for Hurricane Irene.¬†But ‚Äúwe strongly, strongly argue against it,‚ÄĚ he said. ‚ÄúWe urge people to bring their pets to friends or familiy‚Äôs houses or shelters outside Zone A, but if people need to bring them they can,‚ÄĚ said Lavorgna. ‚ÄúThey should come leashed and muzzled.‚ÄĚ
[Updated 10:36 p.m.]¬†North Carolina Governor Bev Perdue told CNN's Anderson Cooper that the state was prepared but cautious. "We urge people to just be really aware. It doesn't sound like a huge storm right now - 50 mile-an-hour winds - but we think it's going to stay over our state 10 or 12 hours and that's where the problem becomes," she said.
Perdue then referenced reports of a bowl-shaped part of the low-lying coastline that is especially vulnerable to high waters.
"That bowl that you were talking about earlier full of water, it's going to dump somewhere, and when it dumps there's going to be a surge of water and who knows what'll happen," Perdue said.

[Updated 10:05 p.m.] Russell Honor√©, the general famous for his management of the federal government's military response to Hurricane Katrina,¬†told CNN's Piers Morgan Friday night that local authorities were right in calling for mass evacuations in low-lying areas along the Eastern Seaboard.
‚ÄúI think we have had a cultural shift in government because, working with hurricanes for about the last 10 to 12 years while I was in uniform, local governments and governors were reluctant to make that decision to evacuate because of the impact [of what would happen] if they evacuated people and the storm didn‚Äôt come," he said.¬†"But the options of not evacuating people, with the warnings that we have now and the accuracy of prediction, (it) needs to be done,‚ÄĚ¬†Honor√©¬†said.

‚ÄúFor some folks this will be the most significant event perhaps in 20 years from a tropical system,‚ÄĚ Rappaport said.
He said unlike typical storms that follow a similar trajectory and curve move toward the sea, Irene"s forecast track comes very close to the shore.
"That means all the weather that's usually, in this case, worst to the east will be much closer to the metropolitan areas this time around," Rappaport said, "and in fact will definitely hit the southern New England area and since there are strong winds, high surge right near the center of the storm, we'll see some of that along the East Coast as well."
[Updated 8:53 p.m.]¬†‚ÄúThe core of the hurricane‚ÄĚ was barreling toward the North Carolina coast Friday night, the National Weather Service said in a bulletin. ‚ÄúThe hurricane is forecast to move near or over the Mid-Atlantic Coast Saturday night and move over southern New England on Sunday.‚ÄĚ

"After conferring with (New Jersey)¬†Governor (Chris) Christie, (Jets owner) Woody Johnson and (NFL)¬†Commissioner (Roger) Goodell, we have determined the best course of¬†action for the safety and well being of all is to move the game to¬†Monday night."
