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.

No, it can't be that bad. It must mean something else, or an error/typo perhaps.

A hurricane with 700 mb pressure would be a Cat 8 or something.

I've been watching it on RADAR for a bit. Last night and early today she was right on track on the little blots they put on the RADAR image. Now she seems to have jogged north noticably and is paralleling the track. That would put her in a bit east of the forecast, wouldn't it?

I think that 700 mb is at a high elevation?

For right now, but who knows if or when she might jog back.

That's the height of the 700 mb level.

holy cow, 700 mb, can that be right?

Do major hurricanes always have such low pressures?

I think that the important millibar figure is the one on line H:

H. EXTRAP  944 mb
but I don't know much about all of this weather-reading, so hopefully more knowledgeable folks will let us know for sure.

Yeah, that's probably it. Luckily, we have somebody here who can explain these things to me so I can pretend to know all about it. =)

Are you the one that had the extrapolitive 3D model that showed the future direction of the storm through "the wall".

It's rare to see them that tightly clustered.

Yes, this is bizarre.

I know it was mentioned. I saw the question, which peaked my interest. Then I looked at a sat view and saw the same thing.

But I never saw an answer...yeah, it would be nice to hear an answer from one of the weather gurus.

We evacuated when Camille was coming up and we didn't know exactly where it was going to hit...but that's the only one I did evacuate for. Lived in NO from 65 to 93...had lots of storms come in, but I don't mess with category 2 or better ones myself...I have to safely be able to evacuate up or get out...

Doc Frank says that the high is moving slower than expected...Katrina is following it...if the high doesn't speed up, we, especially Galveston needs to watch this closely...12% for Galveston now. He's says ck in the AM, if the high is still moving at the rate of speed it is now...Galveston could be the strike point of Katrina.

Gilbert checks in at second lowest recorded pressure, IIRC, with a reading of 888. So 944 ain't good, but I guess it could be worse. I forget which storm had the lowest. I'll see if I can find that.

Wasn't it that unnamed hurricane that hit the keys in the early 1900's?
