And there definitely have to be some larger drops in the eastern eyewall given the dual-pol variables. A lot of liquid in there. Link to comment Share on other sites More sharing options...

Large Zdr and Kdp for a tropical system. It happens to coincide with the bottom of the melting layer so I wonder if it is a result of both a large number of moderate sized raindrops and a few, oblate melting aggregates. Also some nonuniform beam filling reducing RhoHV along a few radials that partially intercept the top of the convection in the eyewall. Birds, I'm thinking. That's the pattern I saw with Hermine. They showed up in larger and larger numbers as Hermine approached, dropping the 0.5 beam's elevation. Hermine was passing over a major fall migration staging area where huge rafts of water birds roost and feed. That's one reason that portion of the coast is a major wildlife refuge. (If I'm wrong, I'd love to hear more about how you distinguish those biological returns from the aggregates and raindrop returns - let's continue that chat in banter or some other forum) Link to comment Share on other sites More sharing options...
heavy_wx Posted October 6, 2016 Share Posted October 6, 2016 Its probably birds. We saw the same thing with Hermine and Alex Aren't birds usually found in the precip-free eye? Also, for biological scatter to produce such large values of Kdp, you would need a lot of birds; that would substantially reduce RhoHV below the general values observed in the eyewall, outside of the NBF reductions I mentioned above.Sent from my SM-G900V using Tapatalk Link to comment Share on other sites More sharing options...

I briefly glanced at the charts for most of the Fla coast last night and it seemed high tides are occuring in the 1-2 AM time frame. Tidal range is pretty small 3 feet at most Link to comment Share on other sites More sharing options...

jm1220 Posted October 6, 2016 Share Posted October 6, 2016 Starting to think more likely than not it won't make landfall in FL. It's a slight bit east still of the NHC track, which as it is has it maybe brush by Cape Canaveral. It'll have to trend back west fairly soon for it to have a real shot, it's clearly headed NNW now and will go parallel, maybe 40-50 miles off the coast at this rate. That will be enough for cat 1 winds at the immediate shore, but the really destructive stuff staying out. And eastern FL lives another day without a landfalling hurricane.

Way too early to make this call, especially with the inner eyewall bouncing around as it congeals with the outer eyewall. Not to mention convection flaring up that could cause wobbles.

That's what we can hope for honestly, because at this point if it does hit it will be devastating in that locale. However, I do think it will make it there or be extremely close unfortunately.

audioguy3107 Posted October 6, 2016 Share Posted October 6, 2016 While I agree it's too early to make a definitive call, if you look at the most recent satellite loop, unless it makes a pretty decent bend to the west, I don't see how it makes it to the coast, it looks like it's already moving parallel and it's well offshore.

HKY_WX Posted October 6, 2016 Share Posted October 6, 2016 Not sure this is any type of eyewall replacement cycle, but more of a reorganization. The hurricane has clearly been under some slight shear/dry air and the CDO was lopsided. The latest satellite/radar shows it working out the dry air and improving organization. Perhaps some of the islands have played an impact as well. Also these posts claiming every wobble north means no landfall are clueless. The storm is right on track.
