    Love the tractor tire hurricanes. Probably keeps this below MH status too.

    Idk that eye has cleared out considerably and cloud tops have continued to cool. Interested to see what the plane finds here shortly.

    Has a shot at cat 3 over the next 24 hours or so imo.

  2. The other thing that’s just crazy to me is that as soon as the eyewall went nuts the coherent band that had been forming disintegrated completely and is now multiple bands all spiraling into the eyewall. That seems like more than just a coincidence.

    Thinking we got an EWRC going on

    Don't think you can call it that yet. Still clear evidence that the band is spiraling inward and some of the "moat" is probably from very strong convection in the northern semicircle of the eyewall. I've noticed this a few other times tonight. If that outer band continues to gain substance then maybe though I think we're probably a few hours from that minimum.

    Not actually, as been mentioned earlier there’s been mesovortices rotating around the eye at times. When that happens the eye will appear ragged/rugged but it’s actually not a deterioration.

    I disagree. While mesovorts are likely present and can warp the edge of the eye to a degree, think there really is an ellipse. My best guess is due to asymmetry in the convective bursts that we've seen tonight. There's typically only 1 burst ongoing at a time while the other side of the hurricane is "quiet".

     

    Not 100% on that one tho and curious to other input if people have it.

    Latest VDM with interesting characterization of the eye

     

     

    Can see that on radar. Though it doesn't look like an EWRC to me. Looks like growing pains of inner core organization.

    Also supported by the fact that there is no outer wind maxima visible on the aircraft data.

  6. Eye diameter on radar is about 10nm at 20,000ft so it is likely ~9.5nm at flight level and we had a drop of probably 3-4mb between passes. From 972 to probably 968ish. Looks like its go time.

     

    Update: 968 confirmed. That's a big pressure drop.

  7. 91kts FL is what they based it on, along with the pretense that the NE quad has not been sampled yet. Decent strengthening from the last pass, but perhaps not as rapid as models had indicated. However, the storm is in good shape for more robust strengthening tonight. Still think an intensity of 110-115kts is a pretty reasonable guess for landfall.

  8. One thing to notice over the past several hours is the transition from spotty and isolated thunderstorm activity to a coherent and organized curved band that is now wrapping around to the south side and over the center. The purple X is roughly where the center is on visible and on radar data. There is some moderate northly shear being imparted on the system today but the improvement in convective pattern suggests that Idalia has continued steady intensification.
