The web site doesn't seem to mention ship reports on the satellite images. I saw the ship report yesterday at 29W, but that was well east of the disturbance.

Here is the report of the NW wind...

28/08 13009 7.9 -38.0 27.5 8.3 330 11 ID= 13009

Not sure if it is a drifting buoy or what.

Sure it would. A west wind is a west wind. Remember: Storm relative motion plays tricks on the eyes.

Also remember...you can have a NW wind and it NOT be a closed circulation. It's called a "Cusp" and you see them in streamline analysis all the time...especially in tropical waves that are close to closing off a low...but aren't there just yet.

This is bouy 41041 in the Central Atlantic located at 14.6n-46.0w.Let's see what changes if any the data from this bouy shows as the system gets closer to that longitud.

Yup...that ID is a drifting buoy.

so what does that mean...the wind is a confusion error?

Check this link out. Shows the Atlantic with sip & buoy reports.

Hope this helps in giving an over all picture of things.

Yup...that ID is a drifting buoy.

That's what I thought...but wasn't certain. Be nice if they stuck some pressure on those things.

Looking at the Visible shot for a moment it would appear that it is starting to look a little better organized this afternoon. Mind you I don't have any good acess right now to loops and stuff so it's just a shot in the dark.

No...it's just a buoy that floats around and gets data on sea temp, ocean currents and winds.

Southflorida, i was just about to post that myself...and also it looks like it is definately heading more WNW than west if you look at the overal lowtomid level circulation.

18z analysis shows shear has increased to 30kts ahead of the wave:

20kts prohibits development, but 30kts might rip this apart.

cheezyWXguy · #34 Postby **cheezyWXguy** » Fri Jul 28, 2006 3:52 pm

if it develops/has an anticyclone over it then it can pass the shear without significant weakening

This is a bit deceptive because part of that is contributed by outflow from the disturbance itself.

Where is this wave? No one says anything, just Atlantic at 12 N and 50 W. I don't know what that is, how many miles from anything would be better.

It appears SAL is trying to build up in front of 99L, but 99L is moving so fast the SAL shouldn't take so much of a toll.

Or is the shear contributing to the outflow channel?

#39 Postby **JonathanBelles** » Fri Jul 28, 2006 3:55 pm

could 99L slow?

HurricaneHunter914 · #40 Postby **HurricaneHunter914** » Fri Jul 28, 2006 3:56 pm

Whats going to slow it down?
