Jeff Masters' latest entry “Hurricane Ike is closing in on Texas, and stands poised to become one of the most damaging hurricanes of all time. Despite Ike’s rated Category 2 strength, the hurricane is much larger and more powerful than Category 5 Katrina or Category 5 Rita. The storm surge from Ike could rival Katrina’s, inundating a 200-mile stretch of coast from Galveston to Cameron, Louisiana with waters over 15 feet high. This massive storm surge is due to the exceptional size of Ike. According to the latest wind field estimate (Figure 1), the diameter of Ike’s tropical storm and hurricane force winds are 550 and 240 miles, respectively. For comparison, Katrina numbers at landfall were 440 and 210 miles, respectively. As I discussed in yesterday’s blog entry, a good measure of the storm surge potential is Integrated Kinetic Energy (IKE). Ike continues to grow larger and has intensified slightly since yesterday, and the hurricane’s Integrated Kinetic Energy has increased from 134 to 149 Terajoules. This is 30% higher than Katrina’s total energy at landfall. All this extra energy has gone into piling up a vast storm surge that will probably be higher than anything in recorded history along the Texas coast. Storm surge heights of 20-25 feet are possible from Galveston northwards to the Louisiana border. The Texas storm surge record is held by Hurricane Carla of 1961. Carla was a Category 4 hurricane with 145 mph winds at landfall, and drove a 10 foot or higher storm surge to a 180-mile stretch of Texas coast. A maximum storm surge of 22 feet was recorded at Port Lavaca, Texas.” ---<>---<>---<>---<>---<>--- Here's the real problem. Forget the wind - it is the AREA of this thing - water is getting sucked UP by this thing in a huge area. I think this will hit as a Cat.2 - no difference, though - the problem with this is NOT wind - it is the Area&Pressure over that area.

I’m just curious as to how the kinetic energy of Ike compares to the kinetic energy released by the Banda Aceh earthquake that resulted in the terrible tsunami.

Yeah, Masters has been talking about people not understanding that the wind is not as important, that it's the energy, and this thing is more powerful than Katrina is energy-wise, which is what is driving the storm surge.

I don't think anyone will ever say this phrase again:
