Looks to be wobbling WSW

General motion is to the NW. Don't let the rotation of the eyewall feature you see on radar fool you. It's "wobbling" around the lowest pressure and makes it look like it's wobbling. In a couple hours it'll look like it's wobbling to the north. Focus on overall general motion.

Insert typical "I'm not a pro" disclaimer here

Alright guys, DEFINITELY picking up. Tree just fell and the gutter got ripped off here in BR.

Nope.. still definitely moving NW. Probably going to split the difference between Lafayette and Baton Rouge.

The eye is filling in pretty quickly now. As showers move into the center the ring of thunderstorms around it weaken and then the winds come down pretty quickly also. The big danger shifts to a lot of flooding since it's moving so slowly. The remaining high gusts, and of course tornadoes, will occur mostly on the eastern semicircle in those really strong bands oriented from south to north, as Janie pointed out. Finally, there'll still be really high water anywhere the winds are onshore and will last until the winds are no longer onshore at any particular location. Good luck to everyone - don't let your guard down until the local weather office and authorities say it's ok to.

Weebles wobble, but they don't fall down.

2/3 of Louisiana is now under a tropical storm or hurricane warning. Only the northern third remains free, for the moment.

Be hard for Center to move anymore N or West. Stalling -or S.W. jogs very possible
Ridge is boxing it in -to N & W

[HurricaneAndrew92]

Doesn't look to be weakening all that fast. Big storm, small weakening.

Latest saved loop.

That feeder band just south of biloxi down to islands is rockin... knocked WLOX off air few mins ago.

Not trying to sound smart but that's exactly what I was looking at

[Janie2006]

It's really interesting to watch the center starting to fill on an extended radar loop. It's the process of watching an intense low pressure system beginning its long march to eventual dissipation, and you only get to see that kind of thing on a landfalling tropical system. I suppose technically you could watch an intense polar low do the same thing, but that's much more difficult.

Meanwhile, one of the most intense bands has set up, south to north, over Harrison County in Mississippi, I'd say at Long Beach-Gulfport north to Wiggins and Forrest County. We've had tornado warnings on two cells in the last 90 minutes in that band...and it isn't going anywhere for the time being. Lots of rain, wind, and potential tornadoes for folks in that area of the coast.

Isaac seems to be doing well over land. It made landfall almost a day ago.

Someone posted this earlier, I wanted to repost.

You can zoom in, and these are from live wind reports. Firefox works well, it's really made for Google Chrome. Not sure how well IE will do.

That has SO much to do with the fact he went over really wet marshland and he did it just as all atmospheric conditions came together for strengthening. A storm strengthening at landfall takes much longer to wind down.

Since we're referring to wind, may I say that it "blows" on I.E?

[Janie2006]

Yep, this is what I was worried about. Multiple tornado warnings are being issued for storms in that feeder band over the Mississippi coast, the most recent one just expired a few minutes ago. That's 4 warnings from that band. Keep your eyes and ears open because these storms are moving *fast*.

Well, the eyewall has been skirting over the steamy marsh land of SE LA during all this time. This has allowed for the system to maintain its strength and that will continue until Isaac gets far enough inland away from the marshy coastline. Hopefully, that will come once the eyewall crosses the I-10 corridor. The eyewall should fill-in once Isaac approaches Baton Rouge and weakening should ensue. But, flooding and TS winds will continue the next 18-24 hours throughout LA.

My prayers to all in LouisianaM Be safe everyone!

My favorite radar loop.. It's goes out to 120 hrs and loads fairly quick..

Many other functions as well.. zooms out to the entire USA for the last 5 days.....
Click the right arrow in the top middle to expand to just radar..

To control the loop use the arrow in the bottom right... Takes a few minutes to figure it out but it's a nice little tool..

You really get to see every wobble very well...

That is WAYY cool! BTW it shows it took Isaac 4 hours to travel from Houma to Thibodeaux. I think I could walk it faster than that!

[ozonepete]

Excellent! It really does load fast. Thanks!
