Hurricane Katrina Live Thread, Part III
NHC-NOAA ^ | 27 August 2005 | NHC-NOAA

Posted on 08/26/2005 10:25:04 PM PDT by NautiNurse

Hurricane Katrina continues to strengthen in the Gulf of Mexico. Currently, the forecast models are converging upon New Orleans. However, all interests in the northern Gulf of Mexico should follow the path of this storm, and be prepared for a major hurricane landfall. Throughout Friday, the official track forecasts moved west, as Hurricane Katrina delayed making the anticipated northwest turn.

The following links are self-updating.

Down to 939 MB, hmm? Isn't that the lowest it has been so far?

I believe so.

BTW, here's a handy millibar to inches of mercury converter (and a few other weather converters): HERE

Would you please grow up and keep this thread on topic and not turn it into another Yankee versus Redneck debate.

Petty bitter people like you make me wish my grandfather never came to America.

I am in Ascension. I am staying if the track stays east of us slightly. If it heads to the west, I am toast. I am more worried about trees falling onto the house than anything else. Have some 80 foot trees about 50 feet from the house. Not very comforting. A 75 mile an hour wind might bring em down. So better safe than sorry. If it's dicey at all, I am going.

We are in north Ascension. Like your situation, there are some troublesome trees too close to the house -- and a bayou(Manchac) right behind it. If it stays east, as you said, we are staying. If if moves too far west, then the house can fend for itself. This one looks too mean to ride out.

Hurricane Katrina Discussion Number 19

Statement as of 11:00 PM EDT on August 27, 2005


reports from an Air Force plane indicate that the intensity remains
about 100 knots...but the wind field is expanding. The minimum
central pressure reported this evening has been 939 mb. The
satellite presentation has been up and down...and has been changing
from a coil to a ring of very deep convection throughout the
evening. T-numbers continue around 5.5 on the Dvorak scale which
also supports 100 knots. Data from the NOAA jet currently sampling
the environment...indicate that the cyclonic circulation extends
upward to about 200 mb and it is surrounded by a large scale
upper-level anticylone. This pattern...in combination with the high
oceanic heat content...fancy words for a warm ocean...along the path
of Katrina...calls for additional strengthening. The strengthening
is also forecast by the SHIPS and the GFDL models which bring
Katrina to 130 and 123 knots...respectively. Changes in the inner
core structure before landfall may modify the intensity of Katrina
up or down...but unfortunately...these changes are not possible to
forecast nowadays with our present knowledge. We can only describe
them as they occur. However...despite these changes in the inner
core...the bottom line is that Katrina is expected to be an intense
and dangerous hurricane heading toward the north central Gulf
Coast...and this has to be taken very seriously.


It appears that Katrina has begun to move toward the west-northwest
or 290 degrees at 6 knots as the high to the northwest of the
hurricane begins to retreat westward and leaves a weakness over the
central Gulf of Mexico. The combination of building high pressure
over the western North Atlantic...and a weak trough approaching the
Gulf of Mexico from the northwest...should result in a pattern that
forces Katrina to turn northwestward and northward toward the
central Gulf Coast. This is also the solution provided by the
global model consensus which the official forecast follows very
closely.

I've got a page of cam links for the next thread. We had problems with several live cams posted earlier--with heavy traffic, they were really locking up the thread.

Down to 939 MB, hmm? Isn't that the lowest it has been so far?

I pulled down all of the "Vortex" messages for 2005, and it appears that 939 millibars is the lowest so far for Katrina.

The only hurricane this year that I saw anything lower in the "Vortex" messages was 929 millibars for Emily back in July (Emily also two other readings less than 939: one at 937, and one at 931; I also found a message that Emily had one reading of 939 millibars.)

holy sh*T.. i forgot since the storm is so huge areas wise the storm sureg will be huge and over a larger area too..
from the discussion...
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.

Landrieu on now; she's worried if Katrina wipes out a 100,000 dispossessed New Orleaners, she'll lose her base.

The "hurricane party" story is a classic example of the urban legend. It never happened, yet it gets more catastrophic with each passing year. The legend which refuses to die is addressed HERE. Scroll down to the "Hurricane Party" heading.

Now, I don't suggest that people didn't die in Camille due to their failure to leave; nor do I advocate that folks in harm's way take Katrina lightly. But the famous Camille hurricane party never happened.

The official line is that they expect 145 MPH sustained winds at landfall, and they're expecting this thing to hammer New Orleans at 8 Monday morning.

Hurricane City has gone from Jim's live analysis to streaming The Weather Channel. The other links I've posted are live; the only exceptions are the Birmingham link which is running an Alabama weather radar, and ABCNews Now who won't go to local programming until late tomorrow.

From what I understand at least one and possibly two local stations in Mobile, AL will begin streaming tomorrow. I'll have those later.

I'm gonna bail for the night - the next two days are going to be wild ones.
