ATL: MARIA - Post-Tropical - Discussion

[Ken711]

That rate of intensification we have just observed is incredible. Maria is now a category 5 hurricane. Dominica is in grave danger.

What was Irma when she was in this area?

[xtyphooncyclonex]

Maria reminds me of a classic West Pacific super typhoon. The ATL season this year, as well, is trying to be the WPac. Wow

[1900hurricane]

KZC for 926 mb is 141 kt. The unflagged 139 kt SFMR is likely legit. Not sure about the flagged 152 kt.

[Kingarabian]

Crazy how these Atlantic systems can deepen so quickly and get strong without having to go CDG.

[znel52]

And that was on the NW quad. NE quad is usually where the strongest winds are.

100% Cat 5, IMO.

northwest is the right front quadrant

Is that always the case? Just viewing IR it looks much more impressive on the eastern half of the storm.

100% Cat 5, IMO.

umm no.. if it is moving wnw.. then 90 degrees to the right would be nne to NE quad..

[psyclone]

EF4 tropical tornado. Remarkable.

[Exalt]

They missed the actual center... winds were still 35 to 40 mph at the lowest pressure.. could be down a 924 mb ..thats a crazy drop from last recon..



233000 1516N 06102W 6972 02528 9287 +182 +099 055014 029 034 001 03

Are those water contaminated? I can't remember what 03 stands for.

[Blinhart]

So it is 160 MPH and 929 mb.

Those only affect the SFMR, but make clear that the true center (which is tiny) was not reached.

[Exalt]

Considering it's that cycle of names, I'm not surprised at all.. Past cycle we had Irene, one before that.. well, we all know.

[Kazmit]

Now officially a cat 5 at 160mph per the NHC.

Incredible what we are witnessing! Prayers to everyone in the islands!! Godspeed!!

[Hurrilurker]

A couple hours ago I said it would be shocking to find a sub-930 pressure on the next recon. Well, it looks like they just got 926 and that might have even missed the eye. So holy crap, color me shocked.

Dom radar, very close. Frightening indeed.

[hipshot]

And that was on the NW quad. NE quad is usually where the strongest winds are.

100% Cat 5, IMO.

northwest is the right front quadrant

I don't think so, NE is the right front quad.
