Hurricane Irene, one of the largest and potentially most damaging storms to hit the East Coast of the United States in decades, is pounding communities from North Carolina and into Virginia, Maryland and Delaware, leaving hundreds of thousands of homes and businesses without electricity. Irene is moving slowly northward, on a track that's expected to take the storm right over New York City and into New England Sunday.
Although the National Hurricane Center said Irene had weakened from a Category 2 hurricane (maximum winds of 96-110 mph) to a Category 1 (74-95 mph) Saturday, and also "lost some organization," the strong winds, torrential rains and potential storm surges in low-lying areas still make it a highly dangerous storm, authorities said.
"The hazards are still the same," NHC hurricane specialist Mike Brennan says. "The emphasis for this storm is on its size and duration, not necessarily how strong the strongest winds are."
At 5 p.m. ET Saturday, the storm was moving at around 13 miles per hour, with maximum sustained winds near 80 mph, and gusts reported at 115 mph, according to the National Weather Service.
On the NPR Newscast earlier, Brennan added that some mid-Atlantic states' coastal areas are going to experience hurricane conditions for several hours and tropical storm conditions for 24 hours.
More than 2 million people along the coast, including 370,000 in New York City, have been ordered to move away from low-lying areas.
The Hurricane Center predicts that Irene won't weaken into a tropical storm until late Sunday, or possibly Monday. The storm continues to threaten many along the Eastern seaboard, with tropical-storm-force winds extending outward up to 290 miles, according to the NHC.

Update at 7 p.m. ET. Signing Off:
We're signing off for the day now — but you can follow NPR's coverage of Hurricane Irene, and track the storm, as well. The Two Way will be live-blogging the storm's effects Sunday morning, as it passes the mid-Atlantic area and closes in on the Northeast.
As we posted earlier, "The Federal Emergency Management Agency says anyone in an evacuation zone who's trying to find the nearest shelter can "Text SHELTER + your ZIP code to 43362."
And this advice came from the Red Cross Twitter feed: "Heading to a shelter? Bring clothes, pillows, blankets, meds, hygiene items & important documents." The service also says not to forget cash and a cellphone charger, and reminds us that sometimes, texts go through carriers' networks when voice calls do not.
Update at 6:15 p.m. ET. Eye Of Irene Returns To Ocean:
Hurricane Irene is making her way back out over the sea near the Virginia-North Carolina border, crossing from land and back over to the Atlantic Ocean, according to the National Hurricane Center. The storm is now expected to move along the mid-Atlantic coast, approaching New York City and southern New England Sunday.
Irene is expected to pick up some speed over the water, possibly reaching parts of Canada by Sunday night or early Monday.

The National Weather Service has issued tornado watches for areas along the coasts of Virginia, Maryland, Delaware and New Jersey.
Update at 1:35 p.m. ET. The "Surge" In Graphic Form:
The Weather Channel just showed a graphic that we thought was interesting, so we went to the original source to get our own copy. It's from the National Oceanic and Atmospheric Administration and shows the water level at the Chesapeake Bay Tunnel.
The blue line is the normal rise and fall due to tides. The red line is what's actually happened today — more than a foot and a half of additional water. And the green line measures how much more water Irene has pushed into the bay — even before she has reached the area.
Update at 1:20 p.m ET. Small Tornado Near Virginia Beach:
As we said earlier, there have been tornado warnings as Irene has moved north. According to The Virginian-Pilot, "a small tornado touched down in Sandbridge this morning, destroying at least five homes and damaging several others in the beachfront community."

From an All Things Considered report by NPR's David Schaper:
"As Hurricane Irene makes its way north, insurance companies are scrambling to get claims adjusters and other personnel in place up and down the East Coast and into New England.
"Companies will be assessing the damage once Irene is through battering the northeastern states. If the hurricane hits as wide an area as is predicted, insured losses could be in the billions of dollars."
Update at 12:20 p.m. ET. New Tornado Warning, In Delaware:
Several tornado warnings have come and gone today, and now there's another. The National Weather Service says east central Sussex County in southern Delaware is under a tornado warning until 12:45 p.m. ET.

Update at 11:15 a.m. ET. More From The Hurricane Center — On Why Any Weakening May Not Mean Much:
Though the Hurricane Center now says Irene may lose some strength before reaching New York and New England, it cautions that:
"Whether Irene is a strong tropical storm or hurricane over New England will make little difference in the expected impacts of damaging winds ... a dangerous storm surge ... and flooding rains."
Update at 11 a.m. ET. In Latest Advisory, A Tiny Shift In Emphasis:
The Hurricane Center just reported that Irene's maximum winds are now about 85 mph, and that it is expected to weaken slightly in coming hours. And the Center changed its forecast just a bit to say that Irene is likely to remain "near hurricane strength" as it approaches New York City and New England. Earlier, it said Irene would "remain a hurricane."

North Carolina Gov. Bev Perdue (D), while saying her state has not been hit quite as hard as had been feared, just asked folks to "please stay inside." The state's only about half-way through hurricane-like conditions, she said, and there's great danger from storm surges and flooded highways.
Update at 10 a.m. ET. A "Long Day" In Hatteras.
In Hatteras, N.C., Midgett Realty has been posting updates on its Facebook wall. At 9:30 a.m. ET it reported that:
"Power has been off for a few hours now, the storm came in south of us and is running up the Sound. Probably will pass us in about 2-3 hours, that's when we'll know how much soundside surge we'll get. It will be tonight before we get out of the high winds, makes for a long day. Several areas of ocean overwash, let's hope the road bed is intact underneath. We need this wind to switch to offshore."

Update at 8:20 a.m. ET. "Hardly A Soul" On North Carolina's Outer Banks:
On Weekend Edition Saturday this hour, host Scott Simon aired a conversation he had earlier today with NPR's Greg Allen, who is in Manteo, N.C.
It was raining hard and winds were gusting up to 50 mph, Greg said. The big fear in the region, he added, is that the "storm surge" as water rises could cause extensive damage. As for whether people paid attention to the order to evacuate, Greg said he saw "hardly a soul" as he drove down the Outer Banks on Friday.
Update at 7:55 a.m. ET. More From The Hurricane Center:
Irene officially made landfall when the eye of the storm touched Cape Lookout, N.C., around 7:30 a.m. ET, the Hurricane Center says.
At that moment, "the estimated intensity of Irene ... was 85 mph," the center adds. And it cautions that while Irene is expected to weaken slightly in coming hours, it is likely "to remain a hurricane as it moves over the mid-Atlantic states and New England" between now and Monday.
Update at 7:50 a.m. ET. Landfall:
The Hurricane Center just reported that the center of the hurricane has made landfall near Cape Lookout, N.C.
Update at 7:35 a.m. ET. Storm Surge Map:
The Hurricane Center has posted a map showing the areas along the coast where water is most likely to rise 2 or more feet as a "storm surge" occurs. As you'll see, the North Carolina coast is most at risk (the dark purple area has the highest likelihood).
Update at 7:05 a.m. ET. Landfall Shortly:
The Weather Channel forecasters say the eye of the hurricane is now only about 10 miles off the coast of North Carolina, near Atlantic Beach. As NPR's Giles Snyder just said on our Newcast, "wind and waves are picking up" as she begins to move ashore.
Meanwhile, here's what the hurricane looks like from space. Astronauts aboard the International Space Station produced this video on Friday:
