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.
Reed Timmer was headed back to Oklahoma to storm chase when he decided last-minute to chase supercell storms in the Catskill Mountains. I've got the full video.
Typhoon Dolphin brought extreme conditions to the islands of Guam and Rota today. Here's how it looked on radar.
On Monday, I documented a big thunderstorm on camera, 3-D radar and high-res satellite.
Wednesday's tornado outbreak was epic and it brought into question whether tornado shelters are safe -- because of a new problem: Flooding.
I haven't blogged lately, but you can see my previous blogs at the bottom of this page. Here are the latest "quick snippets" that I'm putting out on Social Media.
A huge thunderstorm dropped up to a foot of hail in Sydney, Australia earlier today and residents took to social media to show their photos.
