* Along the shores of Lake Pontchartrain near New Orleans, officials sent scores of buses and dozens of high-water vehicles to help evacuate about 3,000 people as rising waters lapped against houses and left cars stranded
* Floodwaters rose waist-high in some neighborhoods, and the Louisiana National Guard was working with sheriff’s deputies to rescue people stranded in their homes.
* The LouisianaNational Guard ceased rescue operations in Plaquemines Parish, saying it felt confident it had gotten everyone out. There were no serious injuries. National Guard spokesman Capt. Lance Cagnolatti said guardsmen would stay in the area over the coming days to help.
* To the east, evacuations were ordered in a sparsely-populated area as a lake dam threatened to break near the Mississippi-Louisianaborder. Officials in Tangipahoa Parish, La., feared the water it would pour into the already swollen river would flood low-lying areas downstream. Louisiana Gov. Bobby Jindal said officials there would release water at the dam.
* The hardest-hit area was Plaquemines Parish, southeast of New Orleans, where floodwaters overtopped at least one levee on Wednesday and left many homes under about 12 feet of water.
* Parish President Billy Nungesser said U.S. Army National Guard troops and local sheriff’s office officials were going house to house through the area on Thursday to ensure that there were no deaths or injuries.
* Clearing weather permitted the use of military helicopters, mostly UH-60 Blackhawks, to aid in the operation.
* In St. John the Baptist Parish, northwest of the city, about 3,000 people were forced to evacuate their homes before dawn on Thursday due to storm surges from Lake Pontchartrain and Lake Maurepas, authorities said.
* In Slidell, a town of about 27,000 people northeast of New Orleans, storm surge from Lake Pontchartrain left the Eden Isle community under about a foot of water.

Utility company Entergy said that included about 157,000 in New Orleans.
* New Orleans’ biggest problems seemed to be downed power lines, scattered tree limbs and minor flooding. One person was reported killed, compared with 1,800 deaths from Katrina in Louisiana and Mississippi.
* Multibillion-dollar defenses built to protect New Orleans itself, after it was ravaged by Katrina almost exactly seven years ago, passed their first major test, according to the U.S. Army Corps of Engineers.
* A Coast Guard helicopter hoisted a couple and their dogs early Thursday from a home in LaPlace, between the Mississippi Riverand Lake Ponchartrain, The couple was taken to New Orleans and reported in good condition.
* The oil and gas industry in the Gulf of Mexico region has so far reported no major storm-related damage to infrastructure. Energy production was expected to start ramping up again, after nearly grinding to a halt as Isaac closed in on Louisiana on Tuesday.
* President Barack Obama declared federal emergencies in Louisiana and Mississippi late Wednesday, allowing federal aid to be freed up for affected areas.

Paul's Prediction: An Up and Coming Minnesota Band: "The Lost Wheels". O.K. I'm a little biased here, but I know great music (and lyrics) when I hear it. If you like rock and blues you'll really like these guys. They have a unique sound and an energy that you don't find very often. Here's the deal: they just released their first CD "Chipper" and they're having a CD Release Party & Concert Saturday evening. If you've had your fill of sugar-on-a-stick at the State Fair and looking for something a little different, come by, say hi, and support local Minnesota music in the process. There's a 94% probability you'll have a good time.
Where: 331 Club in NE Minneapolis, Saturday at 9 pm.
Day 28. Thursday was the 28th day this summer season at or above 90 F. in the Twin Cities. Yes, that's quite enough. I still think we may see 1-3 more before heavy-duty cold fronts start dive-bombing south of the border, but then again a). I kind of like the heat (even without A/C) and b). I'm a naive optimist and I want summer to hang on indefinitely. Under a partly sunny sky highs ranged from 82 at Alexandria to 85 St. Cloud, 92 in the Twin Cities and 97 at Eau Claire.
Paul's Conservation Minnesota Outlook for the Twin Cities and all of Minnesota:
This region is experiencing twice the global average of climate warming. While satellite images reveal thousands of kilometers of milky-cloudy waters along the Arctic coast, suggesting a massive influx of material, the Yedoma has remained understudied largely due to the region’s inaccessibility. By studying the thaw-eroding slopes of a disappearing island, the team found that the tens-of-thousands year old coastal Yedoma carbon is rapidly converted to CO2 and methane, even before being washed into the sea."
