Actually, unless damage/flooding is major from a direct hit, the 14th might be ok, as the storm could be well past NC by then. Of course, if it hits NC or just misses and comes near us, getting there on Friday morning from our area could be tough. And the next 2 storms are long term threats in about 1.5-2 weeks.Every year, my brother rents a house in Nags Head for 2 weeks to get great rates and brings his 3 dogs.

Exactly. As we have seen with the rains from that and Irene, it's no picnic. Particularly in Central Jersey where the Raritan and Millstone come together.A Floyd-like pattern would be bad enough.. we don't need to think of Sandy for every hurricane that threatens
The latest model runs are not good news for the US east coast, as per below, even though Florence has been weakened to a TS (now 65 mph) by SW shear (was expected). Despite the weakening, Florence is expected to enter a lower shear environment shortly and a warmer SST (sea surface temps) region too, which should allow Florence to reintensify, probably to major hurricane status (125 mph) again by Day 5, as per the NHC forecast.
With regard to the models, last night's operational Euro having landfall near Myrtle Beach as a Cat 3/4 storm in 6-7 days and heading inland after that with flooding rains for NC and western VA/WV/MD/PA and this morning's operational GFS having Florence grazing the Outer Banks on Day 6-7, as a Cat 3/4 and then moving up the DelMarVa (weakened to a cat 1, but moving slowly, so flooding rains are a major concern from NC to New England, including our area next Sat, with this outcome - much of this area is already near saturation from a wet summer, so 5-10" of rain on top of that would be a major concern).
Keep in mind that these are model outputs, not forecasts, with the major point being that a US impact is becoming more likely, especially since we're now only 6-7 days away from a possible landfall. And many of the Euro/GFS ensemble members (variations on the operational models discussed above) still show a recurve out to sea, missing the east coast - as well as landfalls in northern FL up to SC. FYI, no models are showing anything like Sandy, i.e., a NW-ward moving hurricane-force storm striking NJ.
A US east coast landfall is becoming more likely, for a variety of reasons, including the weakened storm having moved further south than originally forecast a few days ago (if it's new starting point is further south, it's ending point, i.e., landfall, is more likely to be further SW), plus, as discussed above, the global models are becoming more bullish on an east coast landfall, due to the anomalously strong western Atlantic ridge (strong high pressure) that is in place now and should still be by early next week, which would steer the storm mostly W or NW.
However, there is still the chance that Florence could be picked up by a trough approaching the east coast in the Monday/Tuesday timeframe causing the storm to recurve out to sea, missing the east coast. But the current Euro discounts the influence of that trough and the GFS is influenced by the trough, but too late to have it miss the US. There are other global models and most of them show a US landfall or a close call, including the CMC with a NC landfall and the UK looking like a SC/NC landfall (only goes out 6 days).
It's also interesting to note that of the hundreds of tropical systems that have been within 150 miles of where Florence is forecast to be tomorrow, none of them made a US landfall and that even where Florence will be on Day 4, only 3 storms made US landfall (Dora in 1964 as a Cat 3 in St. Augustine, Ginger, which hit Morehead City, NC in 1971, and the 1933 Chesapeake hurricane, which looks a lot like the 6Z GFS). The fact that we're even discussing US landfalls is mostly due to that anomalously strong western Atlantic ridge.
If folks want the gory details of all the model runs and more the weather board threads are the place to be and for great discussions, the NHC site and Wunderground are great.

Lastly, we're very likely to see Invest 92L, which is several hundred miles SW of the Cape Verde Islands, named Helene sometime today, and we're likely to see Invest 93L, which is just coming off the coast of Africa, near the Cape Verde Islands, named Isaac in the next day or two. Both are long-term threats to the Caribbean and beyond (especially Helene).

The risk of Florence impacting the East Coast has increased slightly from yesterday. If and exactly when and where still remains very uncertain at this point. However, it is important to remain aware of the forecast and ensure you have a plan in place in case more direct impacts threaten your area. Now is the time to review and refresh your hurricane preparedness plans and kits. Regardless of where Florence ends up, it is likely that high surf, high rip current risks, and large swells will begin impacting our coastal and offshore waters as soon as early next week. Refer to the NHC's website for the latest forecasts and information regarding Florence: https://www.nhc.noaa.gov/
Thank you, your info is good and trustworthy
Great info, thanks for keeping us updated! Truly appreciate all that you and Bac do.
Mr. G? Really? Nice man, delivered decent weather forecasts that real meteorologists made in a friendly easy to understand manner, but he's the guy you're going to go to for in-depth analysis of Florence? The man can't even button his shirt properly. Next thing you know you'll be quoting Lonnie Quinn. Stick with posting useful info (like the NHC/NWS links).

Long winded hot air that basically says it could hit from Florida to Maine.
Avoid wasting your time reading his posts
You'll thank me later
Yep, long-winded at times, but many people like the details and insights. You don't, which is fine - you and others are free to ignore my posts, but instead you troll them, cluttering up what is a generally useful thread. Your next useful post will be your first.

That map . . .Today's 12Z (7 am EST data inputs) model suite continues to suggest that a US landfall is becoming very likely in 6-7 days, most likely anywhere from northern Florida to the Outer Banks and possibly even the DelMarVa or NJ/LI/New England (although if it misses NC it would take another day or two to reach those locations). A complete miss, recurving out to sea, is becoming much less likely, due to that highly anomalous western Atlantic ridge (WAR; Bermuda High) I've been talking about, which will likely keep it moving W to WNW, but a recurve is still possible.
For a great discussion of this anomalous WAR, see the post by DT/WxRisk from earlier today, where he references "Black Swan" the great book on statistics and anomalies (which applies to markets and weather and other systems) by Nicholas Taleb, which was spot on: "in anomalous events usual techniques and procedure fail. The tried and tested rules and methods break down," which is why looking at historical analogs for Florence (all of which would show a miss) just won't work, as the anomalous WAR is largely why Florence is likely to make US landfall.

If we still see model runs like these tomorrow the storm's track will then be right at the edge of the NHC's 5-day forecast cone and it'll very likely show a US landfall. And as of right now, the models are showing that the western Atlantic ridge is likely to be strong enough to now allow recurvature and a complete miss. Yes, that could change, but time is running out for that outcome. It would be nice to have a hurricane hunter flight, but Florence is too far away for that right now and we won't get one until tomorrow - without that, the error bars will likely remain high on the storm's track and intensity forecasts.
With regard to the models, briefly, the Euro (still the best model) has remained fairly consistent with a landfall in SC/NC for the past few cycles, with the 12Z model showing a landfall not far north of Charleston, SC sometime Thursday evening, probably as a Cat 2/3 storm, while the 12Z GFS is showing a landfall near Cape Hatteras as a Cat 4 storm Thursday afternoon, but the GFS is known to overdo it on pressure (predicting pressures to be lower than actual). The UK has a landfall near the GA/SC border and the CMC has a landfall near Savannah.
Once again, the exact point is immaterial right now - the point is that these 4 major global models are all showing US landfalls from GA to NC 6+ days out, which is fairly impressive consensus at this range. People in those areas and even down to FL and up to New England, need to pay close attention, as this will likely become a very dangerous hurricane with all the impacts normally associated with such a storm, including storm surge, high winds, potential tornadoes, torrential rains, etc. And the torrential rains and reduced but high winds will likely be felt well inland - and even if it's a landfall in NC, for example, there could still be torrential rains in the NJ area 1-2 days after landfall - and high surf/beach erosion is now a given for most of the east coast starting early next week.

Great question - I was wondering about that too. Jeff Masters addresses it in his latest blog entry, but isn't sure what the impact will be and if he isn't I can't add anything more. He does talk about it being absorbed into Florence and making Florence larger. See below.As an FYI another area of LP popped up between Florence and Carolinas....if that develops into anything (low %) currently that will churn up colder water and affect strength of Florence or get absorbed onto circulation depending ol n movement
For what it is worth - one meteorologists is long range predicting a High pressure system will slide down from Canada and push Florence out as a fish storm.
Network weather guy - but does seem reasonable.
Do not need this storm.
Makes more sense that it would be a low to push the storm
I dont think so if Florence is stronger it will absorb the low. The outlying circulation will suck it in especially if it is just meandering w/o any movement. If it is not being pushed by steering currents/front from the west I do not see any other option than being absorbed by a stronger florence. The only other option is that if it too develops I can see the colder water coming up from the surface stunting Florence's strengthMakes more sense that it would be a low to push the storm

HP is the kicker not another lowA low wouldn't "push". That's not how this works.
Personally I see its energy being absorbed by Florence and Florence doubling in sizeI dont think so if Florence is stronger it will absorb the low.

The NHC 11 pm advisory is out and Florence continues to undergo significant shear and has been lowered to a 60 mph TS, but the shear should relax soon and the rest of the track takes Florence over generally low shear areas that have very warm sea surface temps (near 90F). As a result, the forecast is for Florence to reintensify to a Cat 3/4 130 mph storm (and stronger is very possible) by Day 5, where it will be taking aim at the SE US coast, somewhere between northern FL and NC, with US landfall looking quite likely next Thursday, but still not a given, as there is a dwindling chance that the anomalously strong ridge could be overestimated and the storm still could escape out to sea after coming close to the Outer Banks.Today's 12Z (7 am EST data inputs) model suite continues to suggest that a US landfall is becoming very likely in 6-7 days, most likely anywhere from northern Florida to the Outer Banks and possibly even the DelMarVa or NJ/LI/New England (although if it misses NC it would take another day or two to reach those locations).
