If that swirl of low clouds is the center then there's nothing to track on radar. Convection is racing off to the north now. Ida won't be a TS much longer, and I mean having 39+ mph surface winds not cold or warm core.

.STORM INFORMATION...
AT 7 PM CST...THE CENTER OF TROPICAL STORM IDA WAS LOCATED NEAR
LATITUDE 29.4 NORTH...LONGITUDE 88.4 WEST...OR ABOUT 55 MILES SOUTH
DAUPHIN ISLAND ALABAMA. RADAR INDICATES THE ESTIMATED RATE OF MOTION
IS TO THE NORTH-NORTHEAST AT 19 MPH.


the NWS position does not match the aircraft position at all. The center is closer to 88.8W now. Actually has moved to the NW.

I think we have seen this totally decouple


Mobile NWS is saying the same thing as TWC. Wonder where they get their info... :)

Also, it is definitely getting pretty "breezy" here in Mobile, with fairly heavy rain at times...

Looks like this thing has decoupled almost completely.

wxman57, your theory from days ago that there may be nothing to landfall may turn out to be dangerously accurate! the thing has imploded. interesting to note the best convection now resides off of SW florida in the juicy air and actually extends all the way past wrn cuba...that region has gotten alot of ida rains.

Just looked at a sat pic. Is that the center completely exposed just SE of the mouth of the MS? Surface obs support it. If it is, then it may well never make landfall. New VDM has a fix at 29.1N/88.8W. That's the open swirl on the sat pic below. In addition, looks like cool air stratocumulus flowing into it from the west (that solid light gray cloud mass all along the LA coast to the upper TX coast). Getting cool here in Houston. Have been seeing reports of very strong northerly winds off the mid LA coast this afternoon and evening (our clients). Clearly, cool air is racing out across the Gulf just west of Ida.

NHC says your right

RADAR AND SATELLITE IMAGES SHOW THE CONVECTION THAT WAS NEAR THE
CENTER DURING THE AFTERNOON HAS WEAKENED AND SHEARED OFF TOWARD THE
NORTH. THIS WAS CONFIRMED BY A RECENT AIRCRAFT FIX THAT POSITIONED
THE CENTER EAST OF SOUTHEASTERN LOUISIANA WELL SOUTH OF THE
REMAINING DEEP CONVECTION.

Did you get flooding in your area? At the times, that I watched live reports with reporters in MS, AL, AND FL; MS looked like it was getting pounded the worst.
No flooding reported in my county, Harrison but the county to my west bordering LA, Hancock county has had flooding in low lying areas, evacuations were underway in a few areas in Hancock county a few hours ago but I'll say this, the winds are really picking up now here in west Biloxi, it's beginning to sound like TS Bill outside here tonight. I read on WWL TV4 on Twitter that Ida is now down to 65 mph. Where is the NHC still projecting landfall? Mobile Bay area?

There's a reason why not too many TCs hit the U.S. in November, particularly west of Florida in the Gulf. I wonder if that low-level swirl will even move ashore? Doesn't really matter, though. Once the squalls to the north are inland, Ida's about dead.

I concur wxman57 and will bet against a hurricane straying off the reservation (the caribbean) in November every time.

Yes, I could see the winds were really strong there too. To my very amateur eyes, it appeared the heaviest rains, and bulk of the storm were going into MS all along. The focus didn't seem to be there though. Although, I have to say our local mets were doing a good job to pay attention to all the lower lying areas. Bay St. Louis was getting it pretty bad a couple of hours ago.
The good news is, thus far, it seemed to be moving quickly.

Wasn't based on climo, was based on the projected upper-air pattern across the northern Gulf this week. The Gulf has been ripping with shear most of the season.

Time for bed. Another early day tomorrow.

Hardly any tropical feel to the air tonight, kinda chilly to me. Car temp indicated 64 but Gulfport airport is reporting upper 60's. My first and likely only November TC has been different experience than a TC during the warmer months, kinda like Christmas in July.....The center of Ida is clearly visible on radar south of the MS/AL border. Its a mess down in the Gulf, Ida is badly sheared, cool air is being drawn into the circulation. How Ida has not become ET is beyond me. Hopefully this mess gets out of here for tomorrow. Everyone that is in Ida's way stay safe.....MGC
