Tropical Storm Katrina becomes Hurricane Katrina, according to the latest advisory issued by the National Hurricane Center (NHC). Hurricane Katrina now has maximum sustained winds of 75 mph, making it a Category 1 hurricane. The NHC expects that Katrina could strengthen before making landfall, and then weaken as it moves inland across South Florida through Friday. Models indicate that Katrina will move slight south of due west for next 12 hours, before moving northwest than north after 48 hours. NHC models agree on westward motion for next 36 hours, but continue to diverge significantly after that. One model takes Katrina northeast after 72 hours across the Florida panhandle, while three other models take Katrina significantly westward, indicating Katrina landfall between Mobile, Alabama and Grand Isle, Louisiana. However, the NHC gives two of the three models indicating a westward turn “less weight” because they have not been accurate over past 24 hours. Other aspects of the NHC Advisory include:
bullet Location: 26.1 N, 79.9 W
bullet Direction and Speed: West at near 6 mph
bullet Estimated Central Pressure: 985 mb
bullet Probability that in the next 69 hours, Katrina’s eye will pass within 75 miles of:
bullet West Palm Beach, FL: 99 percent
bullet Panama City, FL: 14 percent
bullet Gulfport, MS: 8 percent
bullet New Orleans, LA: 7 percent [National Hurricane Center, 8/25/2005; National Hurricane Center, 8/25/2005; National Hurricane Center, 8/25/2005]

The National Hurricane Center (NHC) issues a special advisory that Katrina, now a Category 2 hurricane, is rapidly gaining strength as it moves westward. Forecasters expect Katrina to strengthen during the next 24 hours and may become a Category 3 hurricane. Given the drop in pressure, the NHC predicts that Katrina will rapidly strengthen to near Category 4 hurricane within 72 hours. (In fact, Katrina will become a Category 4 hurricane in 61 hours (see 1:00 am August 28, 2005), and will make landfall in only 67 hours .) Other aspects of the NHC Advisory include:
bullet Location: 25.1 N, 82.2 W
bullet Direction and Speed: West near 7 mph
bullet Maximum Sustained Winds: Near 100 mph with higher gusts
bullet Estimated Central Pressure: 971 mb
bullet Probability that in the next 69 hours, Katrina’s eye will pass within 75 miles of:
bullet Panama City, FL: 18 percent
bullet Gulfport, MS: 13 percent
bullet New Orleans, LA: 11 percent [National Hurricane Center, 8/26/2005; National Hurricane Center, 8/26/2005; National Hurricane Center, 8/26/2005]

Louisiana Governor Blanco, determining that the storm will be so big that state and local governments will not be able to handle it, asks President Bush to declare a state of emergency. The exact timing of Blanco’s letter is unclear. The PDF version of the letter is dated August 28. [Louisiana, 8/28/2005 pdf file] However, the Federal News dateline for the letter is 4:27 am EDT August 27. [Federal News Service, 8/27/2005] Governor Blanco’s office and the Times-Picayune will publish the full text of the letter today. [Louisiana, 8/27/2005; Walker, 8/27/2005]

St. Charles Parish issues a mandatory evacuation at 9:00 am. Around the same time, New Orleans Mayor Ray Nagin encourages Jefferson Parish officials to follow the state evacuation plan, which calls for low-lying coastal areas to evacuate first, warning that: “The problem with this storm is that it’s going to compress everything. We have a shorter window to deal with this storm and we’ve got to get people to start evacuating.” Jefferson Parish declares a voluntarily evacuation for most of the parish and a mandatory evacuation for the coastal areas of Grand isle, Crown Point, Lafitte and Barataria. Plaquemines Parish declares a mandatory evacuation and begins evacuating special-needs residents by mid-day. St. Bernard Parish officials recommend that all residents evacuate, although Larry Ingargiola, Emergency Management Director, states that the parish will not declare a mandatory evacuation because it will not offer shelters.

FEMA activates its National Emergency Response Team (Blue Team), deploying to Baton Rouge, Louisiana. [Federal Emergency Management Agency, 8/28/2005] FEMA Director Michael Brown will tell the New York Times that the team arriving in Louisiana today to review evacuation plans with local officials consists of “10 or 20 people.” [New York Times, 9/15/2005]

President Bush declares an emergency for Louisiana, and orders federal aid to supplement state and local response efforts in the affected area. This declaration activates the National Response Plan, and authorizes FEMA to provide appropriate assistance for required emergency measures to save lives, protect property and public health and safety for parishes in the storm’s path and to minimize or avert the threat of a catastrophe in multiple parishes. Bush’s declaration authorizes FEMA to provide appropriate assistance for required emergency measures, including specifically, “[m]easures undertaken to preserve public health and safety and to eliminate threats to public or private property.” In response to this declaration, FEMA Director Michael Brown appoints William Lokey as the Federal Coordinating Officer for federal recovery operations in the affected area. [White House, 8/27/2005; US Department of Homeland Security, 9/7/2005] . As Governor Blanco will later note, this pre-impact declaration is extremely unusual. The last time a president issued a pre-impact declaration was when Hurricane Andrew was bearing down on Florida in 1992. [CNN, 8/27/2005] Note that while President Bush’s emergency declaration identifies 39 parishes, it does not identify the parishes in Katrina’s path, apparently due to a clerical error. [Knight Ridder, 9/11/2005] This omission has no practical effect, and a corrected declaration will be issued on Monday. [US Department of Homeland Security, 9/7/2005]
Note 1 - Reuters will later incorrectly report that Bush appoints William Lokey as the Federal Coordinating Officer, and will imply that such action is somehow unusual. [Reuters, 9/15/2005] In fact, as reflected in the official Federal Register entry, and in the White House release, Brown appoints Lokey as the coordinating officer for Louisiana. This appointment is consistent with standard practice: For each declared emergency, a different (lower level) individual is appointed as the federal coordinating officer.
Note 2 - Knight Ridder (and other news media) will later incorrectly report that Bush failed to trigger the federal government’s responsibility, and that it is not triggered until DHS Secretary Chertoff’s August 31 announcement that the Katrina disaster is an “Incident of National Significance.” [Knight Ridder, 9/11/2005; Knight Ridder, 9/15/2005] In fact, Bush’s declaration (a) effectively authorizes FEMA to provide a full and immediate federal response to the unfolding crisis, and (b) makes the crisis an “Incident of National Significance.” [US Department of Homeland Security, 12/2004] , at 7 (“Note that while all Presidentially declared disasters and emergencies under the Stafford Act are considered Incidents of National Significance, not all Incidents of National Significance necessarily result in disaster or emergency declarations under the Stafford Act.”); [US Department of Homeland Security, 9/7/2005] (granting FEMA full authority to respond to the emergency.) The strategy behind DHS Secretary Chertoff’s much ballyhooed—and inaccurate—August 31 announcement that his declaration triggers for the first time a coordinated federal response to states and localities overwhelmed by disaster remains unclear at this time.

New Orleans Mayor Ray Nagin tells local WWLTV that, “Come the first break of light in the morning, you may have the first mandatory evacuation of New Orleans.” Nagin states that that his legal staff is researching whether he can order a mandatory evacuation of the city, a step he’s been hesitant to do because of potential liability on the part of the city for closing hotels and other businesses.

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

Hurricane Katrina will make landfall in Louisiana in only 48 hours . At Governor Blanco’s request (see Early Morning August 27, 2005), President Bush has declared a state of emergency in Louisiana (see (Midday) August 27, 2005). Low-lying parishes have issued mandatory or recommended evacuations, and New Orleans has issued something between a voluntary and a recommended evacuation (see Morning, August 27, 2005; Evening August 27, 2005). FEMA apparently has sent 10-20 staff members to Louisiana by this time (see 11:00 am August 27, 2005). FEMA publishes a graphic projecting the path of Hurricane Katrina this hour, based on the National Hurricane Center Advisory 21 (see 4:00 am August 28, 2005). FEMA’s graphic indicates that Katrina will pass through New Orleans approximately 32 hours from now, at 2:00 pm tomorrow. [Agency, 8/28/2005 pdf file]
