Looks almost exactly like the old B&W of Camille! - well not the eye but the symmetry.

Hurricane Katrina Advisory Number 21

Statement as of 4:00 am CDT on August 28, 2005


...Dangerous category four Hurricane Katrina continues
west-northwestward but expected to turn northward...
...New tropical storm warnings issued for northern Gulf Coast...

A Hurricane Warning is in effect for the north central Gulf Coast
from Morgan City Louisiana eastward to the Alabama/Florida
border...including the city of New Orleans and Lake Pontchartrain.
A Hurricane Warning means that hurricane conditions are expected
within the warning area within the next 24 hours. Preparations to
protect life and property should be rushed to completion.


A Tropical Storm Warning and a Hurricane Watch are in effect from
east of the Alabama/Florida border to Destin Florida...and from
west of Morgan City to Intracoastal City Louisiana. A Tropical
Storm Warning means that tropical storm conditions are expected
within the warning area within the next 24 hours. A Hurricane Watch
means that hurricane conditions are possible within the watch
area...generally within 36 hours.


At 4 am CDT...0900z...a Tropical Storm Warning has been issued from
Destin Florida eastward to Indian Pass Florida...and from
Intracoastal City Louisiana westward to Cameron Louisiana.
A Tropical Storm Warning means that tropical storm conditions are
expected within the warning area within the next 24 hours.


For storm information specific to your area...including possible
inland watches and warnings...please monitor products issued
by your local weather office.


At 4 am CDT...0900z...the center of Hurricane Katrina was located
near latitude 25.4 north... longitude 87.4 west or about 275 miles
south-southeast of the mouth of the Mississippi River.


Katrina is moving toward the west-northwest near 10 mph. A gradual
turn toward the northwest is expected later today.


Maximum sustained winds are near 145 mph with higher gusts. Katrina
is a category four hurricane on the Saffir-Simpson scale. Some
strengthening is forecast during the next 24 hours.


Hurricane force winds extend outward up to 85 miles from the
center...and tropical storm force winds extend outward up
to 185 miles.


Estimated minimum central pressure is 935 mb...27.61 inches.

Coastal storm surge flooding of 15 to 20 feet above normal tide
levels...locally as high as 25 feet along with large and dangerous
battering waves...can be expected near and to the east of where the
center makes landfall.


Rainfall totals of 5 to 10 inches...with isolated maximum amounts of
15 inches...are possible along the path of Katrina across the Gulf
Coast and the southeastern United States. The hurricane is still
expected to produce additional rainfall amounts of 2 to 4 inches
over extreme western Cuba...and 1 to 3 inches of rainfall is
expected over the Yucatan Peninsula.

Isolated tornadoes will be possible beginning Sunday evening over
southern portions of Louisiana...Mississippi...and Alabama...and
over the Florida Panhandle.


Repeating the 4 am CDT position...25.4 N... 87.4 W. Movement
toward...west-northwest near 10 mph. Maximum sustained
winds...145 mph. Minimum central pressure... 935 mb.


An intermediate advisory will be issued by the National Hurricane
Center at 7 am CDT followed by the next complete advisory at 10 am
CDT.

Based on that map, it doesn't look like Katrina is expected to weaken quite as quickly as a typical TC after she makes landfall. This could end up being an extremely serious problem for more than just NOLA.

Hurricane Katrina Discussion Number 21

Statement as of 5:00 am EDT on August 28, 2005


Katrina continues to intensify and grow larger. An Air Force
reconnaissance aircraft most recently measured a minimum central
pressure of 935 mb... and the winds have responded significantly...
with the maximum flight level wind of 137 kt earlier this morning.
This observation along with recent Dvorak intensity estimates
support the advisory intensity of 125 kt. Additionally...the
aircraft data and ship observations indicate that the wind field
continues to expand. The initial and forecast wind radii have
again been expanded. Although the new official forecast shows no
further expansion of the radii before landfall...this is certainly
possible. Due to the uncertainty in both the track and size
forecasts...tropical storm warnings have been extended both east
and west along the northern Gulf Coast. The intensity forecast
anticipates that Katrina could approach category five status prior
to landfall. The SHIPS guidance actually does forecast 140 kt at
24 hours... but it is also possible that internal structural
changes could cause fluctuations in the intensity... so the
official forecast peaks at 135 kt. While the details of the
landfall intensity cannot be not known at this time... Katrina will
be a very dangerous hurricane at landfall.

Katrina is moving along the previous forecast track... just a little
faster now with an initial motion estimate of 290/9. Dynamical
models are in tight agreement on the turn to the north during the
next 24-36 hours into a weakness in the ridge associated with a
large midlatitude low pressure system over the northern United
States and southern Canada. The model consensus track has hardly
moved since the last forecast cycle and is very close to the
previous official forecast...which the new forecast basically just
updates. The spread in the model tracks along the northern Gulf
Coast is at most 90 miles... so confidence in the official forecast
is relatively high. However...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... both at the coast and
well inland. Preparations should be rushed to completion
throughout the warning areas.
