Re: ATL: NATE - Hurricane - Discussion
Update from Jeff Lindner:
Hurricane racing toward the US Gulf coast
Preparations to protect life and property must be rushed to completion across SE LA, MS, AL, and the FL panhandle
Discussion:
Near continuous USAF missions into Nate overnight have revealed a lopsided hurricane with strong winds mainly confined to the eastern side of the circulation. Overall the satellite appearance is not one suggesting rapid intensification and the pressure has only fallen about 4mb since late yesterday evening. There is deep convection near/around the center, but Nate lack a well defined inner core or well defined eyewall which is likely helping to mitigate a more rapid pace of intensification. As Nate arrives on the US Gulf coast this evening the current wind pattern if it holds suggests area west of the center may see very little impact.
Track:
Nate is racing NNW at 22mph on the east side of a building mid level ridge east of FL and an upper level low over the southern Gulf of Mexico and ahead of an approaching deep layer trough over the central US. Nate may turn a little NW for a period today and then back NNW and N this evening. On this track the hurricane will approach and likely make landfall over SE LA (Mississippi River Delta) and then track NNE toward a second landfall on the MS coast. Nate will then accelerate inland over MS/AL Sunday.
Intensity:
Nate is gradually intensifying and while conditions in the Gulf of Mexico are favorable for intensification, the lack of a well defined inner core should preclude significant intensification prior to landfall. With that said, Nate still has 16-18 hours over a very warm Gulf of Mexico and a 90-100mph hurricane at landfall is certainly possible…high end cat 1 or low end cat 2. After landfall, Nate will begin to decay, but the fast forward motion will bring strong winds well inland over much of MS/AL/N GA and TN
Impacts:
Storm Surge:
Major storm surge flooding is likely along coastal MS and AL and into Mobile and Pensacola Bays.
Significant and life threatening storm surge flooding is likely over extreme SE LA and coastal MS/AL/NW FL panhandle. Storm surge values of 5-9 feet above normally dry ground near the coast will be possible over coastal MS and AL including Mobile Bay and the portions of SE LA outside of hurricane risk reduction systems (levees) S and E of the metro New Orleans area. Maximum storm surge values will be found near and just right of the landfall of the center which appears most likely along and east of the SW MS coast or east of the Gulfport, MS area. Water levels currently being forecast will overtop HWY 90 along the MS coast. Given the current forecast track, storm surge values into Lake Pontchratrain are not expected to reach levels of hurricane Issac in 2012.

Winds:
Winds of 85-95mph will be possible near and east of the center landfall location especially across the lower MS River Delta and then into coastal MS and AL. Given the fair weak wind field on the western side of the system, winds across metro New Orleans may be significantly weaker than those along the MS coast, however any wobble of the center only a slight distance to the west would bring hurricane conditions to New Orleans.
Rainfall:
Rainfall amounts of 3-6 inches will be possible along the track of Nate as the fast forward motion will help to reduce overall totals.

Gotta like where that Euro triangle falls on that chart.

Not really, the models, pretty much all of them, were forecasting an Eastern asymmetrical storm for the last 4 days. So if the models have been calling for this, not voodoo just math.

Re: ATL: NATE - Hurricane - Discussion
From the closet buoy weather data (42001), conditions are not that bad. Gust of 23 knots with wave heights 8.5 ft.
I wish the weather stations on the offshore rigs were sending data since some will probably get the eye.

Re: ATL: NATE - Models
Mississippi Gulf Coast should be in the RFQ. Convective trend of Nate continues to improve. Could make a run at Cat-2 before landfall. I'm thinking somewhere near the LA/MS boarder as landfall point. We are headed out to Orlando shortly for a well timed vacation to Universal. Good luck to everyone in harms way......MGC

Still asymmetrical with vertical alignment issues. That strong southerly flow is effectively shear, which is a good thing, this will come and go quickly on the coast.

Re: ATL: NATE - Hurricane - Discussion
Between the last NOAA pass showing north movement and the next AF pass, I think we might have the northward movement starting. The AF pass would help confirm it.

Re: ATL: NATE - Hurricane - Discussion
Incredible burst of Convection this morning, those dewpoints close to 80 deg F are surely feeding into the circulation.

Those stronger flight level winds are starting to make its way down to the surface.

Re: ATL: NATE - Hurricane - Discussion
I think the AF plane might have missed the center. Showing 980mb east of where they found the wind shift and 983mb at the wind shift. Unless I am missing something.
