Forum Rule Review [Re: Ryan]
      #49511 - Thu Aug 25 2005 11:11 AM

From the Site Usage Rules:

"Low Content Posts: Please do not make single line posts containing no
content (ie, "cool" "hello", "I agree", or something else completely void of
meaning). Or general cheerleading, for example, if you think someone did a
good job and have nothing else to add send them a PM, it works better for
this. Otherwise posts like these just litter up the forums. Remember, CFHC
is not a Chat Room - it is a Niche topic-oriented site, so please attempt to
stay 'on topic' by placing your posts in the proper Forum."

The attempt here is to avoid the use of one-line posts. CFHC is not a Chat
Room, it is a site for Forum-oriented dialogue, so please use it that way.
Reviewing many of the posts over the past two days, most of the one-liners
add nothing to the exchange of information. A lot of them ask questions that
have already been answered elsewhere - sometimes more than once. Before you
ask a question, take the time to review some of the other Forums - odds are
that it already has been answered. Use the PM feature to thank someone for
their input. Personal information does not belong on this site - it just
clutters it. Keep in mind that there is another Forum for asking questions
of a more general weather nature - please use it when appropriate. When you
post a one-liner like "I think that its moving WSW" and you don't include
anything else - like WHY you think this - its going to get deleted by the
Moderators. Sometimes we let this stuff go, but when we start to receive a
bunch of complaints from other site users - we attempt to resolve the
problem. Please help us by following the site rules - it makes the job of
site moderation a lot easier ... and it provides for a more enjoyable
experience for all of the site users. Thanks for your help on this.

TZAMAN: AS a general rule, yes it appears so. In the case of Katrina, most of the activity is on the entire East side of the storm, but is beginning to wrap around the top.

This link will show you the detail of the windfields forecast by the NHC (now incorporated into our maps)
Windfield Details

This link takes you to a close up of the 11am forecast path for Katrina. Note the shape of the wind fields though out the forecast period, which follow this general pattern:

Sketto.... is that what the shape of the "circle" is representing ? The indented south western side to be the weakest in what you had linked?

I have been interested in hurricanes for a long, long time. My knowledge level is not nearly as advanced as the frequent posters on this board.

I would like to thank each one of you for posting such wonderful links and providing well thought out information.

The rings represent the "extent" of the winds in any given quadrant. In the example provided using the current data for Katrina, you see that there are currently NO Tropical Storm Force winds on the West side of this storm. Looking forward 12 hours in the forecast you see that the NHC indicates that the Tropical Storm force winds will wrap around the system entirely as well as the development of a category 1 hurricane wind field (yellow).

We created these maps due to the public always focusing on the forecast line instead of the true area affected.

It appears you are reading these maps correctly.

What factor will keep Katrina from the Pensacola area? Is high pressure expected here?

if you actually read the map key, the darker green represents TD winds

Pressure drop? [Re: MikeC]
      #49523 - Thu Aug 25 2005 11:41 AM

NBC6 news mentioned that the pressure may have dropped to 990mb which would be a considerable drop. It was mentioned in the latest discussion. Can anyone verify this?

radar presentation hints of another WSW wobble.... this could make a big impact relative to who gets the most damage if it indeed reaches Cat 1 or 2 strength.... can only wait to see if this is indeed a trend or just another wobble...

They are going off of a recon report at about 11:05am that stated that the pressure had fallen to 990mb, so it is indeed correct. Flight level winds have kicked up as well and it is possible that Katrina's surface winds are slightly higher than estimated -- 65 to 70mph.

A little confused [Re: LI Phil]
      #49527 - Thu Aug 25 2005 11:44 AM

ok from:
VORTEX DATA MESSAGE
A. 25/1421Z
H. 990 MB
MAX FL WIND 60 KTS S QUAD 1426Z

So, did they timestamp the Vortex data message wrong
or the flight wind measurements?
and the pressure is 990 according to this recon report. hmmm any thoughts on what happened?

The time of the center fix was at 1421z, but they went down to the southern side of the storm thereafter and found higher winds there. The actual vortex message was not transmitted until 1505Z -- 11:05am -- thus allowing for a period where higher winds could be found after the initial center estimate.

Still looks like the west side is still not getting any convection to hold yet but does look alot better then the 11am update.I would say its close to hutticane maybe 70mph.
