ATL: LAURA - Post-Tropical - Discussion

[northjaxpro]

Please everyone post live webcams and other similar links in the Observations thread specifcally made for this cyclone. This will make easier for everyone to find . This will be especially for tonight and the early wee hours tomorrow morning with Laura's approach and landfall.

[Extratropical94]

Extrapolated pressure 943.2 mb
FL 136 kt
SFMR 118 kt

[NotoSans]

Wind data from NE quadrant still shows intensity of 120kt.

I will feel a whole lot better when she makes that turn to the north. Just had a rain band come through Splendora in SE Montgomery County in Texas but no wind yet.

[cfisher]

Wind speed the same but wind field is expanding.

[supercane4867]

Recon might be able to find stronger winds in the northern eyewall. That where's the recent cooling trend in the CDO is taking place.

Bookmark those, will tell a grim story unfortunately.

[GCANE]

Rain rates have been dropping.
Also increasing meso vorts.
More clues of an onset EWRC.

136 kt FL, 118 kt SFMR. Pressure 943 mb.

That's a huge area of 944mb and then the final dip. Absolutely wicked.

Here's looking east toward some rentals with a storm moving NE just by us. Brought a little rain, but it wasn't even on radar. Goes to show sometimes radar can't pick up everything.

[wkwally]

I will feel a whole lot better when she makes that turn to the north. Just had a rain band come through Splendora in SE Montgomery County in Texas but no wind yet.

I was seeing the darkened skys in you direction from here in Humble

[cheezyWXguy]

I recall a graphic much earlier in the thread regarding MPI and that there was a blob right off the coast that supported a much stronger storm, something like 25mb lower than the surrounding area. If that’s the case and no structural issues occur, I don’t see this weakening before landfall

Doesn't look like EWRC here

MPI might be difficult to achieve with such a large eye.

There are plenty of outer bands, but none of them are gaining any prominence. An EWRC might not really start until tonight at the earliest.

[cheezyWXguy]

No doubt, MPI in this area is sub 900. But I think the increase in sst’s in this area would likely allow for it to continue building deep enough convection to insulate it from any shear that may arise at landfall.

What's MPI
