Meteorologist Jeff Matthews, Director of the Weather Underground, a popular web-based weather service, reports that several models indicate that Katrina will enter the Gulf of Mexico by Sunday, “where it has an excellent chance of intensifying into a hurricane. Since the GFS is the only model calling for this stall, it is more believable to assume that Katrina will push into the Gulf of Mexico and threaten the US Gulf coast early next week.” [Masters, 8/24/2005]

Meteorologist Jeff Matthews, Director of the Weather Underground, reports on the latest modeling: “Although Katrina is currently moving just south of due west, the computer track models unanimously agree that a trough moving across the central US this weekend will ‘pick up’ Katrina and force it on a northward path towards the Florida Panhandle.… While New Orleans [certainly] needs to keep a wary eye on Katrina, it seems that the Florida Panhandle has its usual hurricane magnet in place, and the same piece of coast punished by Ivan and Dennis is destined for another strike by a major hurricane.” [Masters, 8/26/2005]

Meteorologist Jeff Matthews, Director of the Weather Underground, reports that the latest computer models indicate, “the threat of a strike on New Orleans by Katrina as a major hurricane has grown. The official NHC forecast is now 170 miles west of where it was at 11am, and still is to the east of the consensus model guidance. It would be no surprise if later advisories shift the forecast track even further west and put Katrina over New Orleans. Until Katrina makes its northward turn, I would cast a very doubtful eye on the model predictions of Katrina’s track.” [Masters, 8/26/2005]

Meteorologist Jeff Matthews, Director of the Weather Underground, a popular web-based weather service, reports: “We may be on the verge of a rapid deepening phase, and Katrina is growing from a medium sized hurricane to a large hurricane. Where the pressure will bottom out after this deepening phase is anyone’s guess, and I believe something in the 915—925 mb range is most likely, which would make Katrina a strong Category 4 or weak Category 5 hurricane by tomorrow afternoon.” He then laments: “New Orleans finally got serious and ordered an evacuation, but far too late. There is no way everyone will be able to get out of the city in time, and they may be forced to take shelter in the Superdome, which is above sea level. If Katrina makes a direct hit on New Orleans as a Category 4 hurricane, the levees protecting the city will be breached, and New Orleans, which is 6—10 feet below sea level, will fill with water. On top of this 6 feet of water will come a 15 foot storm surge, and on top of that will be 20 foot waves, so the potential for high loss of life is great. Given the current track and intensity forecast, I’d put the odds of this at about 20 percent” [Masters, 8/27/2005]

“Katrina is in the midst of a truly historic rapid deepening phase… [and] is now the sixth strongest hurricane ever measured in the Atlantic,” states Jeff Matthews, meteorologist with the Weather Underground. “At the rate Katrina is deepening, she could easily be the third or fourth most intense hurricane ever, later today.” Katrina’s “winds are likely to increase to ‘catch up’ to the rapidly falling pressure, and could approach the all-time record of 190 mph set in Camille and Allen. Winds of this level will create maximum storm surge heights over 25 feet, and this storm surge will affect an area at least double the area wiped clean by Camille, which was roughly half the size of Katrina. Katrina has continued to expand in size, and is now a huge hurricane like Ivan. Damage will be very widespread and extreme if Katrina can maintain Category 5 strength at landfall.” Masters warns that, “Given that the storm is so large and is already pushing up a huge storm surge wave in front of it, even a weakened Category 3 Katrina hitting at low tide will cause an incredible amount of damage. A stretch of coast 170 miles long will experience hurricane force winds, given the current radius of hurricane force winds around the storm. A direct hit on New Orleans in this best-case scenario may still be enough to flood the city, resulting in heavy loss of life and $30 billion or more in damage.” [Masters, 8/28/2005]

“The area from New Orleans to the Mississippi-Louisiana border is going to get a catastrophic blow. I put the odds of New Orleans getting its levees breached and the city submerged at about 70 percent This scenario, which has been discussed extensively in literature I have read, could result in a death toll in the thousands, since many people will be unable or unwilling to get out of the city. I recommend that if you are trapped in New Orleans tomorrow, that you wear a life jacket and a helmet if you have them,” states Jeff Matthews, meteorologist with the Weather Underground, a popular web-based weather service. Masters notes: “Katrina [is] the fourth strongest hurricane ever, and the strongest hurricane ever observed in the Gulf of Mexico, surpassing Camille.… Katrina has continued to expand in size, and now rivals Hurricane Gilbert and Hurricane Allen as the largest hurricanes in size. When hurricanes reach such enormous sizes, they tend to create their own upper-air environment, making them highly resistant to external wind shear.… Katrina is so huge and powerful that she will still do incredible damage even at this level.” Recognizing that he has focused primarily on New Orleans, Masters states, “Katrina will do tens of billions in damage all along the coast of Louisiana, Mississippi, Alabama, and Florida. Mobile Bay could well see a 10-foot storm surge. And inland areas will take heavy damage as well; Katrina will still be a hurricane 180 miles inland, and cause widespread flooding throughout the Tennessee Valley.” Masters ends by urging readers to pray for those in Katrina’s path.
