ATL : TROPICAL DEPRESSION IDA

[Terry]

WXMAN,
I have already recorded 42 mph winds sustained earlier today on Pcola pier, and 38 got a bit ago on my roof.

If your condo is four stories and you recorded the wind speed on your roof, wouldn't that have skewed your readings?

[jdray]

Don't let the deteriorating appearance fool you though. The winds could easily pick back up to hurricane status through baroclinic forcing.

Or the fact that Tornadoes love to spawn in this type of weather...

The really enlarged center appears to be passing southeast of Pensacola right now. Here's the 7PM readings from NWS:

Ida was a fast mover.

[fsusurfer]

Here in destin, and so far ida is a dud

Is the surf at least respectable? Lack of wind could actually help since it won't be knocking the top off of the peaks.

Didn't have enough daylight to go out after work but I did check it. Waves are a couple feet over head, nice form but it almost looked mushy, guess the wind and strong current were giving it that effect.

[Sanibel]

I might be seeing more of a turn towards Pensacola. This one is very difficult to read by radar.


If it is turning against a front it will lose strength.

[attallaman]

I've had a few heavy wind gusts since my last post but now it's back to just steady moderate to heavy rain, not much wind, right now 21mph from the NE, gusting to 35.

That's because it's becoming VERY disorganized and undergoing ET. It's even more complex because it really looks now like Ida is merging with the low-level low to its west and the bottom/east-southeast side of the 500mb trough into one big low pressure area. The readings along the FL panhandle indicate that, whatever/wherever the center is, it is past or very near Pensacola. Winds are north to northeast from Pascagoula to Pensacola but east around Appalachicola.

Surface METARs and isallobaric (pressure change) charts will tell the story with Ida. Pressure fall bullseye pretty much points to a broadening center tracking across and/or just to the east of Mobile Bay. However, I suspect the center will become so broad that it will reach all the way from Mobile Bay to the Perdido River (AL/FL border).

Hey there AJC. What about the northeast winds on the western panhandle and east winds in the Appalachicola area?

I would owe that to the change in structure. SLP is still lower at NOAA buoy 42012, SSE of Mobile Bay. Largest 3-hour pressure falls are also over the area south of Mobile Bay. May be academic as I said earlier. The center is getting broader with each passing hour such that a specific landfall point may not be possible to pinpoint.

So is that the remaining, decoupled LLC? It must be very small, as wxman57 was saying, since winds have already gone north to northeast at Mobile and Pensacola.

Ida's legacy will be its impact on El Salvador. Fortunately for the Gulf coast Ida was mostly a dud.

I just think the center is getting broader.

Agreed. Much broader.

Not directly but a combination from EPAC invest 96E with tail of Ida.

I should have said CA, but I was referring to the folks that died in the mudslides.

[ozonepete]

Ida's been almost completely absorbed now into a large, developing low pressure on the east side of the 500mb trough. Doesn't even look like any strong convection is left, although everyone should stay on their guard.

Interesting to note that Ida made landfall in eastern Nicaragua as a cat 1 but I haved not see reports of deaths there.

Agreed. Much broader.

I do notice those winds over and on the west side of Mobile bay snapping around to north. Looks like soon-to-be-XT-Ida is turning more NE-ward.
