From what I read in the storm surge warning, they are expecting 2-4 feet of inundation on the sound side of the OBX which will definitely cause some big problems if that verifies. Already the coast guard hydro gauge is measuring nearly 3 feet and moderate flooding begins at 3.5 feet. Cedar Island is at 2.4 feet and moderate flooding begins at 4 feet there. The duration of the winds and large area will continue to pile the waters up the next 24 hours and usually experience around this area tells me the sounds rise a bit more than forecast most of the time.


Looks like that includes the regular tides as well. I was talking about the water rise in addition to normal tides being 2 to 2.5 ft. Regular tides are about 2ft or so above MSL.

I think we are all burned out after the last month, plus it is no longer seriously affecting land.

I do think Maria might try to re-strength once it moves east of 70W, as it breaks free from Jose's cold wake.

Down to a tropical storm. And on the real-time tracker, it's passed 40 ACE now, so unofficially it's the third to do so in the Atlantic this month alone. It'd be interesting to go back all the way to 1851 and see if that's happened before (1893 maybe? 1933? No idea) because it hasn't in the satellite era, for sure.

Not a meteorologist, in fact more of an idiot than anything. You should probably check with the NHC or a local NWS office for official information.

Here's a view of Silver Lake harbor on Ocracoke

http://ocracokeharborinn.com/webcams/

I've stayed here 15-20 times and water level here might be up 10-18" from a typical afternoon. Certainly not going to be a huge problem on Ocracoke, thankfully

Note that Maria has had pressure only down in the 970s today. Compare that to those ridiculously low pressures the GFS runs of just 3-4 days ago had for the current time (still available at Tropical Tidbits' archived runs):

Run SLP as of 18Z 9/26 (mb)
18Z of 9/22 929
0Z of 9/23 937
6Z of 9/23 935
12Z of 9/23 939
18Z of 9/23 938

Now watch as we move forward and the runs correct for the bias of too low pressure:
0Z of 9/24 945
6Z of 9/24 949
12Z of 9/24 950
18Z of 9/24 962
0Z of 9/25 964
6Z of 9/25 966
12Z of 9/25 968
18Z of 9/25 969
0Z of 9/26 973

This is just more evidence that the GFS has a serious low SLP bias for TCs at least near the SE US coast. That needs to be fixed, if possible. Regardless, it is important that GFS users like us learn from verifications like this and keep biases in mind.

Ocracoke is one of my all time favorite places in the US. That little slice of heaven has taken so many beatings it’s a relief to see they should be good this go round. :)

is this about the current storm on the Atlantic ?

Dave Barker saw it coming timely, in 1970 ;)

or was there a Maria storm heading for Jamaica at the time ?

Once again we have Hurricane Maria. I do think that it may say stronger longer though, since water warms up some as it moves east.

Why is Maria still being officially called a hurricane when Recon found no such evidence at the surface?

US Navy evacuates residents from storm-devastated Dominica
The US Navy performed rescues off the Caribbean island of Dominica in the aftermath of Hurricane Maria. The storm has left the majority of the island's buildings damaged, and dozens of people are still missing.

Bermuda radar. Outer bands lurking to our west. Conditions should decay tomorrow as Maria passes by.

Tropical Storm Maria Discussion Number 49
NWS National Hurricane Center Miami FL AL152017
500 AM EDT Thu Sep 28 2017

Maria's satellite presentation has not changed much during the past
six hours, with 15-20 kt of northwesterly shear continuing to
displace much of the deep convection to the east of the center.
Despite the discrepancy between aircraft observations and Dvorak
estimates noted yesterday, a pair of ASCAT passes from a few hours
ago showed maximum winds in the 50-55 kt range. Even with the
assumption that the resolution of the ASCAT data may not have
revealed the highest winds, an analysis suggests that Maria has
weakened back to a 60-kt tropical storm. Little change in intensity
is anticipated during the next two days while Maria moves over sea
surface temperatures of 26-27 degrees Celsius, and while vertical
shear decreases during the next 24 hours. After 48 hours, a marked
jump in shear and much colder waters should induce more weakening,
and model guidance indicates that Maria should complete
extratropical transition by day 3. The extratropical low should
then be absorbed by a larger system over the northeastern Atlantic
by day 4. This scenario is in agreement with guidance provided by
the NOAA Ocean Prediction Center.

Maria is becoming embedded in the mid-latitude westerlies and is
now moving toward the east-northeast, or 060/7 kt. The cyclone is
expected to turn eastward very soon, but then turn back toward the
east-northeast in 36 hours as a positively tilted trough moves off
the New England and Atlantic Canada coasts. The speed differences
among the track models are not as significant as they were
yesterday, although the updated NHC track forecast was nudged
southward for much of the forecast period to follow an overall
modest shift in the guidance envelope.

FORECAST POSITIONS AND MAX WINDS

INIT 28/0900Z 36.8N 71.0W 60 KT 70 MPH
12H 28/1800Z 36.8N 68.8W 55 KT 65 MPH
24H 29/0600Z 37.0N 64.9W 55 KT 65 MPH
36H 29/1800Z 38.0N 59.7W 55 KT 65 MPH
48H 30/0600Z 40.0N 53.1W 55 KT 65 MPH
72H 01/0600Z 46.4N 35.5W 45 KT 50 MPH...POST-TROP/EXTRATROP
96H 02/0600Z...DISSIPATED

That was the first pass and not the subsequent passes through the center. Oh well, not all that important just think Maria was weakening and just like when strengthening trends are found by Recon the NHC usually goes with the latest report, here they didn't.

I hope both Maria and Lee can hold on for just a few more hours. The entire month of September was active with at least one storm active every single day. I don't want that to be broken

This is the first time since 2004 that this happened. At that time the continuous cyclone activity lasted from 24 August to 3 October, and now we also will be near to it (Harvey regenerated on 23 August, but it seems that Maria will became extratropical today or at the latest tomorrow).

I'm a little skeptical that Maria will make it to 18Z.
