They will probably go up when jt pokes out over water next run

Why is it that the first hurricane I’ll experience has to mess up my travel plans, anyways is the surface circulation that far out in the gulf? It’s looking sheared.

Matthew Harding (Wichita, KS) 12-Sep-20 01:01 PM
Given the 11 am position from the hurricane center, it does still appear to be tilted. But, the mid-level center looks like it's trying to become the dominant center on radar (kind of like what Isaias did when it was going over PR). As Pat said, recon is enroute, so we'll see how much of this conjecture is true. (edited)

“A major concern with #TD19 will be heavy rainfall and flooding. The storm is working through an envelope of very moist air (throughout the atmospheric column) and could slow down as it approaches the Gulf Coast. Ensemble signals for heavy rainfall are already significant.”

Glen Heinz (Greenville, SC) 12-Sep-20 01:44 PM
[#NerdTweet] #TD19's landfall intensity has a wide uncertainty range. Shear is forecast to approach 20-25 kt as west winds above 500mb encroach. However, if TD19 forms an inner core soon and the shear isn't enough to disrupt it, 2-3 days of intensification makes the ceiling h...

If the storm is moving slower, wouldn't it make sense that the wind field would degrade after landfall? Not so sure that premise is "full of shit."

Wrapped a conference call with our colleagues at @NWSNewOrleans a few minutes ago. Early messaging is 8-12 feet of surge possible from mouth of the MS River east along the MS coast with current track of #Sally. Important to note that is very track/intensity dependent.

An east to west track is much worse for surge than south north. It not only has a better wind vector, but it will have an extra 12-24 hours to push water. Surge will over perform whatever the category is

I think we need to worry less about the exact strength and more about the physics. The angle of attack is worst case scenario. And the damage from Katrina is still there. The barrier islands are a shadow of their self (edited)

Its initialization of simulated IR and intensity has been spot on so far, and it was uncannily good with Laura too, I definitely think it can't be entirely ruled out and even the NHC says they're not discounting it and RI

Given the essentially stalling Im wondering if freshwater flooding might be the big issue besides the surge
If that core of heaviest rain parks over NOLA, certainly won't be a good situation

Alex V (Wausau, WI) 13-Sep-20 05:16 AM
It's not a complete stall, the storm will still be moving albeit slowly
But surge + rainfall = backed up swollen rivers.

Based on analysis, we are about 12 hours from go time. Around midnight tonight she will pass into an area with near zero shear and 100 OHC. She Will have about 36 hours for an RI cycle.
👍 2
20kt / 12h 10.4% 11.5% 10.9% 25kt / 24h 21.2% 42.4% 31.8% 30kt / 24h 15.4% 28.5% 21.9% 35kt / 24h 10.2% 28.5% 19.3% 40kt / 24h 8.2% 28.5% 18.4% 45kt / 36h 18.8% 39.8% 29.3% 55kt / 36h 11.3% 18.7% 15.0%
45kts in 36 hours looks like a decent bet. So 90kts at landfall is well possible
IR/WV differential shows very strong hot towers trying to move around the east side. She may already be starting an intensification phase. I would say cat 2 is likely, and nhc agrees. Cat 3 is less likely but possible still.

Avatar
beard (fort worth) 13-Sep-20 12:09 PM
The trough that has caused NHC to shift their track west will be what keeps her from being anything more than a very weak cat 1. I'd be more worried about the 24 hour straight dump of rain than the winds.

HMON and previous Hrwf runs all had sub 970 landfalls. Now hwrf is falling back.

Cat 2 is basic pattern recognition. LLC keeps outrunning convection due to stiff synoptic low level flow. Seen it several times MDR south of strong sub-trop high. When this corrects Sally will quickly achieve hurricane strength. Cat 2 remains a reasonable forecast.

The shear vector isn't aligned with the storm's motion so the storm will "feel" its influence a little more, apparent in the sheared cloud pattern/vertical tilt
SHIPS has shear increasing over the next 36 hours, as does most guidance. Maybe it's wrong 🤷‍♂️

The 18z GFS ingested ~48 dropsondes from the earlier NOAA flight and the early sondes from the G-IV. So the initialization should have a fairly good grasp on the shear/tilt of #Sally. Looks like ~10 kts of NW shear. Thermodynamics as a whole look great.

All finally centered over nearly stacked circulation.
Sally is under very low shear now.
Avatar
Pat Kepka (Russell Co. KS) 13-Sep-20 09:04 PM
New data from the evening recon flight into #Sally indicates that the low-level center is getting tugged toward the new convective burst on the NE side, a trend that would likely lead to intensification if it persists overnight.
Yes it looks like it finally stacked
Also note the recon center is way ENE of the nhc position at 8pm
Likely due to this pull
Also 18z euro coming in at 971 mb

Some hail is evident aloft associated with a vortical hot tower over the center of TS #Sally. Uncommon for TC convection to have hail cores and speaks to the intense updraft there, which is also over 55kft tall. Sally may intensify more rapidly if this convection persists/wra...

Satellite derived shear is very low over its Gulf Path. Mid South system is stalled so I'm not too concerned about shear through tomorrow. By then it'll have established some of its own outflow.

[#NerdTweet] Because #Sally's pressure fell rapidly, we now have a wind field that is tight on the north side but broad on the east side of the center. We could see a temporary pause in rapid strengthening while the circulation adjusts to the new pressure field and symmetrize...
This is actually shown well on HWRF, which stops deepening for a few hours until the current hook structure wraps up into a more circular core, at which point quick intensification resumes. https://t.co/KKyV7jOfL4

so, the waters on the coast there are pretty shallow, so OHC is low....but shallow water means less cool water below for upwelling to occur if it stalls. it will just keep churning the same shallows over and over, maybe feeding off of the higher OHC to the south

The only way upwelling becomes a major issue is if it slows to under 2 or 3 mph. Right now, it's not expected to do that. It's warm all the way to the coast and at depth, I could see this strengthening all the way up to landfall.

Avatar
Royce Sheibal (Papillion,NE) 14-Sep-20 02:35 PM
Given the shelf topography and stratification presumed here, the depth-averaged temperature Td increases as the bottom depth becomes less than ddo=85 m, the depth of mixing over the deep ocean given this rather stable stratification
from a paper on OHC. so the upwelling won't do much because the average depth temp is actually HIGHER than in deep waters

there is an asterix in this case. there is a major drop off just to the south. water will be pushed UP that drop off and into the shelf area, this could rapidly cool the coastal water IF the water advects to the north

buoy 42039 is just below the main shelf, it has a south facing escarpment that leads down into the depths. this is exactly we're we would expect upwelling to occur in this case. the question is...how far will the upwelling make it north? the storm is moving into an area /w a much lower depth and wider shelf
but there is of course, de soto valley, which is a really narrow deep trench in the middle of the shelfs. very high OHC but very easy to upwell it would seem

It looks to be intensifying and building it’s structure again. Pressure is dropping and bands seem to be wrapping around the back half now. Probably because it started moving again and took a north turn (negating some shear and stopping upwelling.
Now that it’s moving again and moving more north it should have an easier time now, Royce.

It probably won’t have a solid eyewall ring at landfall but those mid bands are starting to wrap.
Avatar
Royce Sheibal (Papillion,NE) 15-Sep-20 10:47 AM
PWET shows that low level moisture has fully insulated the SW side of the storm. this should allow it to intensify w/o that dry air being an issue
both RIPA and SHIPS refuse to remove RI from their odds tables. still 10-15% chance, which is decent. ADT is now higher than the estimated wind, which means we'll likely see winds come up within the next few hours
10-20 kts of RI is still possible before landfall, so dont count her out

Avatar
Alex V (Wausau, WI) 15-Sep-20 10:54 AM
I don’t think she will do a crazy RI at this point, but can easily see a steady re-intensification to Cat 2 wind speeds.
Lightning appearing more on the slightly more upshear side, we all know what that means.
Anyways I said yesterday Sally will take one of two landfall routes, a smaller more compact Cat 3 eyewall, or a larger Cat 2 eyewall. Sally seems to be taking the latter route and steadily intensifying back to C2, which is arguably the worse case scenario since a larger hurricane (albeit weaker) wind field will increase flooding hazard with higher surge and river backflow.

KMIS is on the NW quad /w hurricane force, KVOA is on the NE quad /w hurricane force. there is a deep water measuring station right in the middle of the eye. water flow is from the south, allowing it to bring in deep warm water from the de soto valley
the underwater geography of this area has really prevented any upwelling, which is amazing and unlucky

Remember, the bet is that it would reach Cat 2 at some point, not landfall as one.

there is a scale, based on what the wind is at teh surface that you reduce the pressure based on that scale

shear isn't that bad right now. she's in a neutral 20kts or so. and if she starts to move /w the shear she might get a little boost.

I'll say. I did mention yesterday Sally making another run for intensification once she began her north movement negating some of the shear and also moving into a less upwelling-prone environment. Her intensification episode yesterday had more to owe to the fact she unexpectedly had a small eyewall for a brief period, what we are seeing now is more on track with the original forecast. (edited)

Sally's radar presentation looks like a stable Cat 1-2, measurements are Cat 1 but Sat is indicative of intensification. I still wouldn't write off a slow crawl but upwards towards Cat 2.
It all depends if she wants to keep getting fat or not.
Arguably a slimmer but stronger eye is preferable, Sally remaining a low-mid Cat 1 and expanding her hurricane windfield is worst case scenario for a system like Sally, it would cause river backup, higher surge, and power outages over a much wider area and much more damage overall. (edited)
It already is, in fact.
It's part of the reason I tell people to not get so hung up on Category, a fast moving pinhole Cat 4 eyewall hitting an uninhabited marsh is not going to fuck shit up nearly as much as a slow moving fat Cat 1 windfield that hits several towns and cities at once with a larger fetch over water.

Royce Sheibal (Papillion,NE) 15-Sep-20 04:09 PM
yeah, in thermodynamics, the more meso-cyclones that are able to stabilize around the center of the vortex, the more likely it is to form an eye
1 then 2 then 3, then around 6 it just pops
usually we dont get to see it happen in such a close environment to a radar site, so this is actually quite interesting
she's basically hugging the coast, and still making pink IR tops is just crazy for a cat 1. this is something that michael should be doing. Laura wasn't even that cold.

This is coming up in places like every single storm, the southern eyewall isn't substantially weaker because it's not showing higher velocities on Radarscope, it's just because it's further away and people still don't get that
People think the costal radars are magic and can get both sides of the eyewall this far out

That is where I need to disagree, the SS scale is still good for determining wind impacts.
It can be thought of as an extension of the Beaufort scale.

That's like saying a 120mph wind gust means the storm is a 120mph storm. Instead of rating it on what it's constantly doing.

Given how long these barrier islands are getting thrashed we may see a reshaped coastline after this, actually we will see a changed coastline (especially in areas more erosion-prone).

unless someone has some non-dropsonde wind data to confirm, probably not

Just checking. Either way, Sally did some serious damage. Hopefully folks are all right.

She made a good attempt at a Cat 3 run but I think 105 is correct
Avatar
Royce Sheibal (Papillion,NE) 16-Sep-20 10:17 AM
the ominous 130mph dropsonde was likely a meso-vort that ate the dropsonde. in other hurricanes that would have been enough to up the wind rating, but they were being very careful not to make quick responses
✅ 2
at that point its a judgetment call by the NHC. in laura they had flight level winds and inbounds that indicated a cat 4. but it wasn't until they got dropsonde data that they pushed the winds up higher officially. in this case the other data doesnt' support 130mph at surface, so the dropsonde likely was eaten by a sharknado, which doesn't justify upping the sustained winds
this does however, beg the question, why don't we have a better method of estimating storm intensity than just 1min sustained? should we go 10 min sustained like japan? should we use IKE? or SDP?

@Royce Sheibal (Papillion,NE) I will leave that question in the hands of the more academically profecient people. My 2 cents is that the priority shouldn't be getting somehting "exactly and precicely correct" but should be "what will best and most accuratly convey to the general public the severity of the situation" (edited)

Royce Sheibal (Papillion,NE) 16-Sep-20 10:28 AM
@Joey Prom (Lafayette, IN) I agree totally. I work in government and my masters is in the public admin field. translating science to basic english is hard enough as it is
we could probably transition to the RAMMB KE system, or the IKE system for damage, and peopel wouldn't notice. both systems use either cat 0-5, or 0-6 for IKE
this 2
for instance, katrina makes landfall as a cat 3. but it's IKE rating was a 5.6 (top end damage maker)
✅ 2
Avatar
Joey Prom (Lafayette, IN) 16-Sep-20 10:30 AM
0- 6 would get the public's attention for sure. That could be good, letting them know there is a new system
✅ 2
Avatar
Royce Sheibal (Papillion,NE) 16-Sep-20 10:30 AM
laura was a high end cat 4, but well before landfall it's IKE rating was near 5.5, almost a katrina at landfall
Avatar
Joey Prom (Lafayette, IN) 16-Sep-20 10:31 AM
I suspect that this season will see some changes, jsut because of how high profile the severity could be
without gettin too into the weeds, how is IKE determined?
I am an engineer, so I want to know how things work, 😉

so, max values for sally based on ADT estimates: IKETS(TJ) 70.931 SDP 4.248
surge damage potential of 4.2. roughly a category less than laura
mind you ADT rated sally as a high end cat 3. not a high end cat 2. so keep that in mind.

ADT?
Avatar
Royce Sheibal (Papillion,NE) 16-Sep-20 10:37 AM
advanced dvorak technique
using convection size, shape, intensity to predict pressure and wind
a storm that has very high ADT but low reported winds is likely a - in the process of RI, or b - a big chungus that has much larger wind field than normal
wind * radius = constant, where the constant is the rough kinetic energy of the storm

ADT estimates for Sally were actually just below cat 4
Winds lagged behind structure

Royce Sheibal (Papillion,NE) 16-Sep-20 10:40 AM
yup. she had a lot of room to grow if she didn't landfall. and her wind field was fairly large

radar estimates were likely too high due to brightbanding (hail in the signature) so 36" didn't fall. there were surface reports of up to 26" as of this morning

Hail in a tropical updraft?
That is rare.
Avatar
Royce Sheibal (Papillion,NE) 16-Sep-20 03:53 PM
rare but it happens in very intense storms. you could see very high ZDR in the forward flank last night
the combo of strong hot towers + dry air infiltration = good mix for hail
and by hail, we're talking graupel probably, small stuff, but large enough to mess with radar cals

I would be less concerned of the state of the battleship itself (battlehips are tough as hell) and more of the possibility of it breaking it's moorings and plowing into a structure. (edited)
But there doesn't seem to be any reports of that happening.
