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.
History was made by Hurricane Iselle this week and I have some of the most impressive images and maps from the storm.
We're monitoring a total of six storms in the Atlantic and Pacific, and some of them are record-breakers.
As is often true this time of year, the tropics are busy, with five notable named storms. Among them are three storms near Hawaii, and Bertha is back for the seventh time.
There's been a lot of news on amateur drones since I tested the DJI Phantom Quadcopter for storm chasing purposes last fall. Not to drone on, but let's take it from the top.
Today I'm pleased to announce a new suite of world radar maps and advisories from the national weather services of several countries on AccuWeather.com.
There's much ado this week about the polar vortex visiting the U.S. this week, but it wasn't long ago that we set over 7,800 cold records in July.
