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.
There was a blizzard warning in effect for Hawaii on Dec. 25. What sorcery is this?
There are a number of holiday (Black Friday, Cyber Monday, Holiday) sales happening this season with gadgets that can help you observe the weather.
Tragedy struck on the day before Christmas Eve this year when four people were killed by a tornado in Mississippi. Tornadoes also struck Georgia, Louisiana and (on Christmas Eve day) the Carolinas.
Siberia has fallen to -66 degrees as the cold air pool grows and throws off a storm to soak Japan with 2 feet of rain and even more snow.
This week's powerful California storm has now brought a report of a tornado in southern L.A. this morning, and additional reports of waterspouts this afternoon
A very deep storm in the North Atlantic, not far from a strong high pressure system, will cause incredible wave heights midweek.
