Grand Isle, LA already 70mph winds

[LSU]

Winds are gusting to 45 at the NOLA Lakefront Airport about 40-50 miles north of Grand Isle.

Grand Isle in the past 15 minutes got blasted by 90 mph gusts.

This is quite incredible considering how far away the storm is. The NHC was dead wrong on the wind field of this storm. A hurricane warning should have been placed in SELA this morning. There is still not one, even with these winds!!!

Looks like some warnings have gone up.

At 9p Grand Isle getting gusts of 68.

Venice 61.

Port Sulphur 62.

My guess is that they're still showing data from when Katrina was nearby - they may still not have power at these locations or something like that. Their calibration could also be totally off because of Katrina. No other sites along the coast are reporting anything even close to that, nor should they be.

I'm not sure about that Purdue. That latest cell that just rolled through here in Houma gave my neighbors wx station a gust of 42mph. Earlier today, we had a couple gusts around 40mph also with those bands.

My first thought when seeing these numbers (in the 50's an hour and a half ago) was that the Grand Isle station was reporting bad information. Could have been given old info -- doubtful -- but more likely, that the new equipment was not calibrated. That theory seems not to cut it after checking four separate stations along the coast. Each station reported different yet similar (gusts within 8 mph of 90 mph) gusts.

As strange as the numbers look, how could four different stations be so close while giving indepedent numbers if each was inaccurate?

still reporting 68mph gusts as of 9:00CTD at Grand Isle. What the heck is up? Do we have any S2k members down that way to verify. If this were just one station reporting this it would be easy to discount, but there are too many stations in south LA reporting high winds to just ignore

What about the buoys/stations just offshore from Grand Isle? I can't get the GOM buoys to come up...

GDIL1 - no recent reports, BURL1 (SW Pass) failed Aug 29.

Dauphin Island is a good bit north and east of these apparent "stations."

A lady on a NOLA forum is saying she is talking to her husband who is captain of a ship down there. They have unofficial equipment that is telling them wind is gusting in the 60-range.

I can say with reasonable certainty those reports are overdone... there probably are some 40-50 mph gusts in squalls, but not more than that.

[skysummit]

Right now, station KL49 which is appx. 19 miles NW of Grand Isle is reporting sustained winds of 21mph gusting to 31mph.

[mcw]

Higher velocities near or at the immediate shoreline.

[TS Zack]

We have no squalls outside and sustained winds of atleast 20mph, gusting to 40mph. Just had flying debris hit the car.

It's been interesting watching bouy 42001 tonight too.
