ATL: IDA - Remnants - Discussion

[Highteeld]

Pretty good symmetry on Dvorak too

[Extratropical94]

145kt FL at 750mb

[Owasso]

145kt FL

[aspen]

Note to self: never overestimate the possibility of an EWRC with a storm that could RI to landfall.

Edit: wow 145 kt FL/130 kt SFMR. Looks like they missed the eye but holy jeez this is intensifying fast

Just skimmed the 25 pages since I went to bed at 11 pm. All I can say is wow. May God have mercy on the people of Southern Louisiana.

And a lot of people didn’t evacuate

Think we might have support for 150MPH...

There are already many instances of this in the WPAC, in this case I find Ida's case similar with Mangkhut (2018).

Ida’s CDO on Dvorak definitely surpasses Laura’s and even Michael’s in terms of symmetry and frigidity. The eye is going to be similarly warm to the latter’s, too.

145 kt FL wind and 131 kt SFMR, yep this one is definitely trying to make a run for a cat 5

NOAA seems to have quirky readings most of time.

Catch a couple hours of sleep and all hell breaks loose.

Never good when Senior NHC Scientist talks about fearing for an area. Praying for all in harm's way.

Ida is definitely at least 130 kt now and likely stronger, tying 1856 and Laura. We are likely looking at Louisiana’s strongest landfall on record since 1851.

1000mb This level does not exist in this area of the storm above the surface level.
948mb (28.00 inHg) Surface (Sea Level) 26.2°C (79.2°F) 25.4°C (78°F) 85° (from the E) 98 knots (113 mph)
925mb 219m (719 ft) 24.2°C (75.6°F) 23.4°C (74°F) 105° (from the ESE) 148 knots (170 mph)
850mb 961m (3,153 ft) 21.6°C (70.9°F) 18.4°C (65°F) 125° (from the SE) 143 knots (165 mph)

NOAA plane has faulty extrapolated pressure. Disregard. But wow at the winds…

[Highteeld]

161 knots at 902 mb. cat 5 winds not making it below 928 mb... for now

Ida intensified from 70 kt category 1 to a 125 kt category 4 in exactly 24 hours. That's an increase of 55 kt, more than enough for RI or even ERI. In fact as I posted in an overview more than 100 pages ago (http://www.storm2k.org/phpbb2/viewtopic.php?f=59&t=122135&p=2932299&hilit=database+person#p2932299), it is on par with the ERI phase of Laura and only below Camille, Anita, Freeport and Celia in terms of GOM ERI in August.

The eye literally cleared out within the span of the past fifty minutes on IR. That is one of the fastest such clearings I have personally observed.
