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.

The chances of it going to TX are extremely slim. There is a trough coming into the west coast that will help build a ridge through the rockies and into TX. To the right of that, there will be the weakeness the storm is currently looking for. She is slowly trying to round the western periphery of the Atlantic ridge, then it's probably almost due north to the coast.

I remember one hurricane that went in circles in the gulf for days before finally making landfall. Can't remember which one it was but it was fun to watch. Does anyone else remember?

You've lost perception of the time span of a track forecast.

you will not be going to new orleans on monday...i suspect contra flow will begin tomorrow unless the models change dramatically. even if things change in the next couple days on the track....nola will be a ghost town on monday. again..assuming the forecast models dont change much in the next 12 hours.

I think you're right. I just told my husband, who was going to go with me, that he probably won't need to miss work Monday afternoon. I have many dear friends and co-workers in New Orleans, so I'd better start getting the guest bedrooms ready for company.

I would expect a fully formed eye when the satellite eclipse ends. She appeared to be entering a good intensification cycle.

Water Vapor shows the outflow increasing to the NW of the system, this is usually a good indication that some turning will occur within the next 12 hours or so.

any dry air that could weaken this thing? In the WV, the air is not as moist to the north, but I do not know if it is dry enough to cause weakening. Any thoughts?

I have lived in Tampa, Covington, La. and Pensacola over the years. It is an interest that has never left. The west edge on the latest water vapor image looks to be entraining some dry (black) air. That might be a blessing.

Elena was the one that went ashore a couple times and in circles a bit, if I recall correctly. I lived in Pensacola then. It got to the area south of the city, stopped, headed to La. and came back as a nothing.

They just got in there, I haven't seen a VORTEX but some of the more raw data is coming in. Looks like they have a max flight level wind around 120mph so far.

Do you think it will turn earlier than the NHC forecast and hit east of New Orleans?

Thanks. I've been wracking my brains on that one for months.
wunderground.com has some neat hurricane history but the maps were too cluttered to make anything out and going year by year was too tedious. I'll try by name.
