Is the eye tilted? That point is not center in the eye??

The background satellite image does not update as quickly as the recon data.

This is general and not so specifically about Irma (though it was written in the CONTEXT of Irma)

A fantastic article about how to follow hurricanes online - how to sort through the clutter of model data, etc. on social media. Really excellent.

Think the NHC will bring the winds down to 175mph. Were winds higher in the NW or NE quads?

probably not a reduction in the wind yet. Need to sample the N and NE eyewall first

Alyono,
What are your thoughts on track prediction? Just E, W or through Fl?

at least close enough so that some part of South Florida gets hurricane force winds

Sen. Rubio on TWC right now sounds very distressed. I really am nervous and think this is going to be a second major blow in the season.

A correction to a tweet I posted earlier about using a special radar feature to view the double eyewall:

I think the worst is over, it looks like the eye of Irma is now north of San Juan and slowly moving away from PR.

Tropical storm conditions here for a couple of hours here (eastern central PR), some trees down, we lost power but no damage to houses/buildings. It looks like we dodged the bullet big time!

[HedwigTramp]

If you are in life threatening conditions, Get out fast. If you have several days before impact, as part of your evacuation plan, include taking many many many pictures of your stuff. Even if you are hunkering in, take tons of pictures of your stuff and upload to the cloud.

Sorry for the delay, my monitor suddenly went off.

Are you on an app or a mobile device? I know sometimes viewing twitter messages doesn't always work from a mobile phone, especially if you have data restrictions set up.

No, i use a normal desktop.

How can we see those twitter messages ?

Are they blocked for you? Use a modern browser (Chrome, IE 10+, or Firefox)?

Yes, i´m using the most recent FF, ublock and privacy badger are switched off. Hmm

Irma just won't quit. Stronger still? I don't know what to say...

[tweet]https://twitter.com/wxmvpete/status/905585259797991426[tweet]

If she breaks 900 mb, I'll be even more speechless.

Gfs really knocked these intensity estimates out of the park, and everyone thought it was crazy. Plenty of low shear and warm water to go, and it looks like Irma is going to miss all the mountainous islands.

Maybe this will help to lessen some of the ridicule that's been hurled at the GFS of late.

Double post - please delete

[Aric Dunn]

umm last few radar images showing the inner eyewall possibly merging again with the outer on the west side..

about to really deepen again ?

Published on Sep 6, 2017
At NASA a 3-D image was created using GPM's radar (DPR Ku band) data.
GPM's radar revealed that the extremely powerful storms rotating around the eye were reaching altitudes greater than 7.75 miles (12.5 km).
The tallest thunderstorms were found by GPM's radar in a feeder band that was located to the southwest of Irma's eye.
These extreme storms were reaching heights of over 10.0 miles (16.2 km).
GPM is a joint mission between NASA and the Japanese space agency JAXA.

And another follow up tweet on this:

I know Philippe, and will have to tell him to use Kdp rather than Sdp as the abbreviation for specific differential phase (one of the few times I am able to correct him, he is a brilliant TC researcher).
