ATL: IDA - Remnants - Discussion

[Iceresistance]

AF305 SE Eyewall dropsonde, CAT 5 winds are not far from the surface . . . (Note that these are instantaneous wind speed measurements)

Instantaneous wind speeds?

Wind speeds occurring at a moment, basically 1-second wind speed . . .

Pray for our bayou communities of Lafourche parish. (Where I live) it will never be the same

Our prayers are with you and your community, stay safe and check in with us when you can! I’ve learned lots from your posts throughout the years of going through storms in Louisiana.

Not sure this was the smartest idea

Definitely seeing more mesovorts.
Another indication an EWRC maybe trying to form.

My friend's parents live in Houma and opted to stay. There was obviously less warning with Ida considering her state four days ago, but I hate to think of what's going to happen here that could have been prevented.

An ounce of prevention is worth a pound of cure - downcasting due to wobbles or delayed ERI is a dangerous game.

Hope all of you here who are in the path stay safe.

Last recon had 145 knots at the surface if true, the will make it a cat 5

Would it have time to complete an EWRC before landfall?

New dropsonde measured 140 kt at the surface, this is a cat 5.

Most likely not but it’s not going to change things unfortunately except maybe a tad less wind

Landfall of eyewall now expected at 10:27am central time.

Won’t even have time to start it. Radar appears to be showing yet another failed attempt for the outer eyewall to become established. There was a pretty good sized moat for a while, but it is quickly filling in from the se quad up
