Dry air entrainment now apparent in Ivan

[Windy]

Lots of dry air in the north quad, looks like it's doing a good job eroding the north end of the storm:

wow..hard to argue with that....also hard to argue with the results this is having as wind reports across the board are not indicative of a cat 4 just offshore.

That's good. My home owner insurance is quite high enough, thanks.

Does look like that is so, Ivan will probably maintain his current intensity now, rather than continue to strengthen.

Would you just give it up already? It has 135 PROVEN by recon, and it will go in at 135. Just drop it man.

I hate dry air.
Hurricanes should be Wet Wet WET..

[dennis1x1]

there is no recon backing up 135.......last was 125.....and again...im only reporting current observations...mobile 39mph...new orleans 37.....based on the windfield advisory they should be getting hurricane force.

other interesting note is that winds havent increased in the last 3 hours noticeably in either of those cities....

I surely hope he is weakening! That would be a blessing for everyone in his path. It's still a very bad situation, but it would still be better!

Grr wow are the loops bouncing around like crazy??

[Rob Beaux]

one question...Someone mentioned that it was a a 1 minute max min for the recon and that the data stations on the bouys reported 10 minute winds. Could this also be the situation with the wind reports out of Mobile and N.O.

IF so then why dont they change the way things are measured either the weather statiosn or on teh recon.

I only set up a couple of stations and collected the data, so this could be slightly off the correct terms.

Seems this is.. a great media outlet.We get to watch the weather channel . Overepaid goofs.. in weather gear. It is embarrassing to me. Trust all islander's are faring well..We hear nothing about you otherwise.

are one minute averages. Offshore synoptic ones are 10 minute averages. However, a 39 mph sustained wind could easily have gusts around 60mph since the gust spread is much higher over land than over water (a JTWC years ago showed that the peak gusts were about 25% higher than a one minute wind while over land they were at least 50% greater).

FWIW .. I've been watching DhWeather's site for the last few hours. He's pretty close to what will be landfall (Bay St Louis) and the highest gust he's reported is 43 mph. I know it will go higher (maybe a lot?) in the next few hours, but hardly Hurricane force yet.

Bay St. Louis is about 70 miles West of current apparent landfall location. I t is aboout 45 miles NE of downtown NO if I remember correctly.
