Seven years ago today, I was blogging about how Hurricane Katrina's track had switched west on the models to center on New Orleans. With the models shifting soon-to-be-Hurricane Isaac's track to center over New Orleans last night, the new levees protecting NOLA were completed just in the nick of time, it would seem.
And it only took $14,500,000,000 to fix the levees. Unfortunately, the 133-mile line of defense only protects against a "100-year flood." Katrina was a "500-year" flood and there are already reports surfacing of corner-cutting to the new levee construction, which would reduce that further.
The effect of the Gulf Oil Spill is another wildcard. I blogged in 2010 about how only 2.7 miles of wetlands reduces a hurricane's storm surge by 1 foot. If there's anything "fortunate" about Isaac's expected track, it's that the wind should be off the land in the southern marshes of the state (assuming the storm comes through or east of NOLA).
The map above from ERMA shows the heaviest beach oiling from the spill. Note that the worst was on the barrier islands of southern Mississippi and Alabama, but most of that has been cleaned up now and I would assume didn't cause permanent (hurricane-relevant) damage, in non-wetland areas. There is a whole report on this topic if you're interested in reading it.
Let's hope the models are wrong.
Over 200 stations may have broken daily low temperature records this morning, with a handful of monthly records. I take a look at North Carolina and Pennsylvania.
The record lows tonight will also affect the Southeast, pushing in cold air not felt since I was in college 20 years ago!
A number of interesting weather and astronomical phenomena were caught on film last night on the AccuCam Webcam Network.
Pennsylvania set a number of cold weather records Sunday and today, and more is on the way.
Folks I can't stress enough how dangerous the weather will be this Valentine's Day Weekend, with Blizzard conditions, RealFeel temps below -40 and snow squalls.
Part of the Rodanthe Pier collapsed into the ocean Thursday as an arctic front passed through and homes in Oak Island remain damaged from an earlier storm.
