The National Hurricane Center (NHC) issues its first hurricane watch for the southeastern coast of Louisiana, from east of Morgan City to the mouth of the Pearl River, including New Orleans. A hurricane watch likely will be required for other portions of northern gulf coast later today. Models also indicate Katrina will strengthen and could become a Category 5 hurricane, and the hurricane will likely move west-northwest during the next 24 hours. Katrina’s eye has begun a concentric eyewall cycle. Models now agree that Katrina is likely to make landfall in the next 72 hours over the northern Gulf Coast, however, the models disagree about where Katrina will make landfall: Two models indicate landfall will be near Morgan City or Intracoastal City, Louisiana. The other guidance ranges from Grand Isle, Louisiana to Pensacola, Florida. The official NHC forecast calls for landfall in Southeastern Louisiana—in 48-60 hours. (In fact, Katrina will make landfall in only 38 hours .) Other aspects of the NHC Advisory include:
bullet Location: 405 miles southeast of the mouth of the Mississippi River.
bullet Direction and Speed: West at 7 mph.
bullet Maximum Sustained Winds: 115 mph, with higher gusts.
bullet Estimated Central Pressure: 940 mb.
bullet Size: Hurricane force winds extend outward from center up to 65 miles; tropical storm force winds extend outward up to 150 miles.
bullet Probability that in the next 69 hours, Katrina’s eye will pass within 75 miles of:
bullet Panama City, FL: 12 percent
bullet Gulfport, MS: 18 percent
bullet New Orleans, LA: 19 percent [National Hurricane Center, 8/27/2005; National Hurricane Center, 8/27/2005; National Hurricane Center, 8/27/2005]

The National Hurricane Center (NHC) warns that Katrina, still a Category 4 hurricane, continues to intensify and grow larger. The NHC reiterates the hurricane warning for Louisiana to Florida, and expands the area covered by a tropical storm warning. It warns further that, “While the details of the landfall intensity cannot be known at this time… Katrina will be a very dangerous hurricane at landfall…. It must be emphasized that the exact landfall point cannot be specified and that Katrina is a large hurricane that will affect a large area,” warns the NHC. “NHC now expects Katrina’s path to move north later today.” Other aspects of the NHC Advisory include:
bullet Location: 275 miles south-southeast of the mouth of the Mississippi River
bullet Direction and Speed: West-northwest at 10 mph
bullet Maximum Sustained Winds: Near 145 mph, with higher gusts
bullet Estimated Central Pressure: 935 mb
bullet Size: Hurricane force winds extend outward from center up to 85 miles; tropical storm force winds extend outward up to 185 miles
bullet Probability that in the next 69 hours, Katrina’s eye will pass within 75 miles of:
bullet Panama City, FL: 11 percent
bullet Gulfport, MS: 26 percent;
bullet New Orleans, LA: 29 percent [National Hurricane Center, 8/28/2005; National Hurricane Center, 8/28/2005; National Hurricane Center, 8/28/2005]

The National Hurricane Center (NHC)‘s midnight advisory leads with: “Potentially catastrophic [Category 5] Hurricane Katrina continues to approach the Northern Gulf Coast…sustained hurricane-force winds nearing the Southeastern Louisiana coast.” Already, a wind gust to 98 mph has been reported from Southwest Pass Louisiana. Katrina remains quite large, and will likely cause storm surge flooding of 18-22 feet above normal, with increased surge to 28 feet in some areas, and may overtop New Orleans’ levees. Some changes to Katrina’s structure indicates that there could be some weakening, although the NHC reiterates that Katrina likely will still be a very dangerous Category 4 hurricane at landfall. Other aspects of the NHC Advisory include:
bullet Location: 90 miles south-southwest of the mouth of the Mississippi River; 150 miles south-southeast of New Orleans
bullet Direction and Speed: North-northwest at near 10 mph
bullet Maximum Sustained Winds: Near 160 mph with higher gusts
bullet Estimated Central Pressure: 908 mb
bullet Size: hurricane winds now extend 105 miles from the center; tropical storm force winds extend 230 miles [National Hurricane Center, 8/29/2005]

Katrina, still an “extremely dangerous” Category 4 hurricane, with sustained winds at 135 mph, is now moving north at nearly 15 mph and its eye is now approximately 40 miles southeast of New Orleans and 65 miles southwest of Biloxi. The National Hurricane Center expects Katrina to pass just to the east of New Orleans during the next few hours, and then move into Southern Mississippi. Katrina has grown yet again, with hurricane force winds extending 125 miles from the center, and tropical storm force winds extending 230 miles. NHC warns that storm surge flooding of “10 to 15 feet… near the tops of the levees… is possible in the Greater New Orleans area.” Minimum central pressure has increased to 923 MB.
