Imminent landfall, probably into NJ

 

 

This is what I was concerned about. ECMWF filling Jose's 500mb vort enough to bring Maria back west. Fortunately, based on this solution, it still had Maria far enough east bringing it over signficantly cooler SSTs thanks to Jose before bring it nearto the Mid-Atlantic region. Maria would be a similar storm to Jose by that point.

 

What we have to watch for with modeling evolution the next few days is if the ECMWF begins to trend towards filling Jose's resulting mid-level weakness faster. That could allow more ridging bringing Maria further west in track over much warmer and untouched Gulf Stream SSTs.

As long as Jose is strong enough to keep the break in the ridge, Maria will follow that break in the ridge and go out to sea. If that break closes up, Maria has a path to the lower 48. 

But where does he create a break in the ridge? See 12z Euro. She's going to make landfall or come very close, this run.

The 12z Ukie only goes out to 144 hr, but you can forsee a similar outcome to the 12z euro out 192 hr.

The Euro says the trough kicks Maria OTS at the very last second, I don't see it. Anyway it's a day 8-9 forecast. Just good to see an exciting model run

Looks like the weaker Jose is the more of a chance Maria has to come west.  Other thing is the speed of Maria.  The faster Maria moves the more west it can get before the trough affects it.

could have sworn you said it was imminent that it was heading to NJ? 

[Roger Smith]

Maria within range of PR/VI radar now

Shouldn't those posts be in the Jose thread?

It's confusing because one storm affects the other.  I hate dividing things like that anyway, it's way too time consuming to switch between different threads.

Yeah I did say that, because that's what should have happened. The trough is way back over the Northern plains as Maria is approaching coast. Either way, it's still a solid battering for many.

Most likely both, as what Jose does is directly dependent upon where Maria ends up. It's worth talking about it here as well, in my humble opinion. Probably wrong though. 

The specialization of dividing things like up is going too far IMO, it's better having things in the same thread, especially when one impacts the other.

The GFS has had similar solutions - either Maria follows Jose out to sea, or Jose dies, but a trough kicks Maria out to sea. Either way, with Jose pretty much assured to stick around at this point, landfall seems unlikely given the set up. You would really need a Sandy level left hook, or for Jose to weaken much faster than forecast at this point.

[Windspeed]

Yes get used to seeing Jose's name in this thread because after impact on PR/VI, its 500 mb influence and how that evolves is the #1 major player concerning Maria CONUS interaction and track uncertainty.

[SnoSki14]

Side note: Jose has been around for 2 weeks and will likely stick around for several more days.

Kinda crazy how he'll dictate what happens to the US. Crazy times, it's been a long time since we've had such a great hurricane tracking season.

I think PR will be aided by an ERC...relatively speaking, of course...my guess is 130mph LF intensity on PR.

[40/70 Benchmark]

Jose is hybrid at this point...which allows it to maintain more intensity.

Jose is so weak and over such cold waters, I wonder what's keeping him on life support for so long.

Hurricanes typically don't weaken as much as people think north of the VA/NC 80 degree SST cutoff after late August.  They will usually plummet to around 85-90 mph and then can be stubborn beyond that because they are often being aided by some sort of upper level feature and or semi ET transition.   In June/July/most of August more weakening seems to occur.  This is likely due to SSTs being cooler as there is frequently a lag and less likely to see ET transitions or dynamic upper level features helping systems in summer

No. For an east coast LF want to see Jose (remnants?) move west, into the coast, irrespective of intensity, so the weak trough is collocated with the east coast.

[JC-CT]

The 18z hurricane models moved south again. It could still end up going across the south side of the island.

So the models showing Jose's remnants going west into NJ and then dissipating over PA are the ones that would bring Maria closer to the coast.  The other thing is that Maria needs to move at a quicker pace to avoid being influenced by that front coming in from the west.  Maybe Jose's remnants moving west would also slow down the front?

[40/70 Benchmark]

I think if Jose were to remain seaward, then a weaker vortex does leave a less prominent path out to sea, but ideally it would move west...true imo.

Speed relative to Maria really isn't the issue.

As modeled it's a kicker bc it's too progressive. But that can and likely will change. If that trough is deeper and/or goes negative it won't act as a kicker.

Watch that PNA ridge that's now showing up around hr 198.

so these posts def belong in the Jose thread. 

[NJwx85]

If you've noticed, Maria seems to follow Jose, thus Maria's eventual fate is very much reliant on the eventual outcome of Jose. 

If you're looking for an East coast landfall from Maria, you want Jose to either dissipate or move far enough West that it allows the ridge to rebuild to the North. 

If Jose ends up getting kicked out, it leaves the weakness in place and Maria likely follows.

Not a chance it gets down to 130 by LF in PR. You expect a ERC to take 35mph off it? Or do you feel there is something else not being mentioned that will reduce wind speed?

[adiabatic13]

I realize this is a hobbyist site, but at critical emergency management planning times such as we're in this afternoon with regard to Maria, it might be helpful to have a pro forecast thread. There are a lot of guesses being posted here with authority that new eyes in the VI and PR might not understand are derived solely from "weenie" hopes and dreams. I even saw someone state that Maria would be landfalling as 130 mph storm; while that's not outside the realm of possibility there's no meteorological evidence for that forecast at this time. 

Incidentally, ERC seems a hip term around here, so understand that until we see a weakening trend with Maria's strong inner ring of convection an ERC is NOT imminent. 

 

Edit: I didn't mean for that to sound overly critical, but as a weather event, Maria's forecast is unique in that it's people's actions over the next several hours that will determine whether they live or die tonight. I'd hate for someone in PR to start spreading the word in his local community that the media is overly hyping Maria as he just read on AmericanWeather that the storm will weaken a lot before the morning.

It's just his guess. Though concentric banding is getting better organized, we have no way to know how that will evolve, even in the short term, or how quickly an ERC could progress. There is even a possibility that concentric eyewalls could develop and persist all the way into landfall with the outter eyewall not being intense enough to result in a weaker inner eyewall at landfall. All this stuff is a big unknown until it actually evolves IRL.

I know the Raw T# has been a topic of some drama yesterday, but, I did want to mention that Raw T had been fluctuating and nearly stationary around 6.5-6.7 for hours now, but is back on the rise. It's currently up to 6.9 and climbing steadily.

Understandable and I get where he's coming from, and you for backing him up.  HOWEVER, me personally, I'd really love for those "guesses" to be backed up with their reasoning, data and methodology of coming to that guess. I think that is what people are commenting on in this instance.
