Assuming that the second trough misses also, as it's modeled to be lifting out, and Jose survives the shear, then you get an Easterly flow under the Southern periphery of the high.

Unless we have a troff in the lakes or a closed low in the Ohio valley, it's a pretty wimpy easterly flow. It's not impossible, but I'd rather see much faster movement at landfall like Irene or sandy. Pretty easy for a 2mph SW drift to turn into a 2mph NE drift in later runs.

I'm not saying that I favor a solution similar to the 12z Euro at this time, but I understand why the Western solutions cannot be ignored.

that plus all the crowds are gone

We had three swimmers at jones beach last Saturday, three!!!! Gorgous weather and big surf (Irma). As soon as that swell dropped Jose swell filled right in. Pretty rare for the east coast.

Jose definitly has the worst appearance of its (later) life so far. I wouldn't be surprised to see NHC downgrade to TS at 11. 

Then there's a ton of shear and upwelled waters in its future. This could easily be a weak TS by the end of the weekend

We have a  New England/Canada cruise out of NYC planned for Sept 16th with stops in Boston on the 19th stops in Maine the 20th and 21st and the maritime provinces thereafter. Based on current projections just how rocky will it get?

 

Thanks in advance

I'm no expert for marine forecasting but it seems likely to me that cruise ships off the coasts of mid-Atlantic and off of the coasts of New England

are going to modify their plotted courses as a function of avoiding choppy seas secondary to Jose.

I don't know if this helps you, but here's the end of the most recent Forecast Discussion from the Mt. Holly/Philadelphia office regarding marine conditions in the NJ/DE area:

.MARINE...
No marine headlines through Thursday. Patchy fog possible
tonight. Otherwise, leftover showers should end this evening.
Long period 3-4 foot se swells continue on the Atlantic waters.

OUTLOOK...
Thursday night-Friday night...Generally sub Small Craft
Advisory conditions expected. Seas forecast to be 3-4 feet.

Saturday-Monday...Conditions may reach Small Craft Advisory
levels as seas may build to 5 feet. Sct afternoon showers.

Rip Currents...
This evening...Moderate except added HIGH risk of RC to 3 NJ
counties for the remainder of this afternoon...our calculator
has no more than moderate risk but a report of lifeguard concern
prompted the issuance.

Thursday: Moderate risk for the formation of dangerous rip
currents. Long- period (10-14 sec) southeasterly swells from
Hurricane Jose continue.

Looking ahead...a low or moderate risk is expected Friday then
larger longer period swells from tropical cyclone Jose should
arrives this weekend and we expect moderate or high risk days
from Saturday through at least next Tuesday with swells building
to 5 to 6 feet and period lengthening to near 15 seconds. Even
surfers can suffer injury from wave slam and certainly swimmers
are asked to follow lifeguard and other official advice... and
in my opinion...in these upcoming conditions its not worth the
risk.


The link to the full discussion is here if you're interested. I hope you get to go and that you have a great time!

Considering the position of Jose's turn to the west from tonight's 11 pm NHC advisory and the preponderance of ECMWF ensemble members, my confidence that Jose will avoid U.S. landfall has increased. Periodic outlier forecasts by the UKMET and most recently the 12z ECMWF were noted but don't appear to fit the current pattern, generally forecast synoptic evolution on the ensembles and GFS, or historic hurricane climatology.

With respect to climatology, approximately 18% of hurricanes that passed within 100 nautical miles of Jose's 11 pm position (1851-present) made U.S. landfall. Had Jose made the turn to the west at a latitude of 1° further south, that figure would have been approximately 60% higher at 29%.

There remains a larger probability of landfall in Canada. That probability has increased somewhat. Nearly half of hurricanes from the above sample that did not make U.S. landfall ultimately made landfall in eastern Canada.

Great post! I do have a few observations and would disagree on the landfall possibilities though.

1. Models are coming in quite a bit stronger and further west as a result. The recent drop in shear and increasing organization point to this as well. An anticyclone is forecast to build over Jose tomorrow and further reduce the shear. A stronger storm will be closer and further west in this case. 

2. The NHC position seems too far north to me. All the recent microwave passes indicate the center has dropped below 25N instead of moving west. The MLC appears to be at 24.5N as of a few hours ago. 

3. A NE landfall is looking much more probable at this time to me with the interaction between Jose and the shortwave energy sitting over PA. This would swing him NW and close to or near the coast.

My personal experience with watching many years of NE weather is that dry August weather yields insignificant tropical coastal activity in NE.

August definitely hasn't been dry here in NJ.

South NJ and Delaware is not the NE, the rules are a bit different in concert with the local climate. 0z Euro is something fierce, it will keep evolving this far out which is the scary part. Irma had a long history of trending west under high pressure ridges.

What do you mean something fierce? How is it different from the 12z Euro from yesterday?

The possibility that Jose may have been a little south of the NHC's fix was why I looked at a position 1° further south in latitude. There was a higher landfall probability associated with that position, but still fewer than 1-in-3 such storms made U.S. landfall. I thought the 0z ECMWF had a reasonable track. There remains a degree of uncertainty, so things could still change.

I haven't really looked at that angle. But tropical cyclone tracks can be a function of the prevailing pattern, so a dry pattern with lots of ridging over the NE could be one that limits opportunity for TC landfall in the NE. Windows of opportunity could be limited to times when such patterns relax.
