Folks, longtime lurker who has tried to be quiet and learn the dark arts of New England weather forecasting. I live on the Vineyard, have an oyster farm and several commercial boats in the water. I’m getting spooked, pulled every boat I can out already but have a 35’ Downeaster with nowhere to go and a lot of oyster gear/rafts in the water … this may be The One, and I get excited for heavy weather like anyone … but this one, as currently modeled, would be disastrous … thanks for sharing your knowledge with us plebes - and remember that some of us with interests in Henri’s path are looking towards any possible guidance and forewarning … be safe.

Potential hazards from Henri include:

* Damaging wind: highest winds will be focused east of track.
* Flooding rain: heaviest rain should be focused along/west of track.
* Storm surge flooding: focused east of track.

Keep in mind tides will be astronomically high this weekend
along both coasts. Track will ultimately tell us which coastline
is most at risk (east coast vs south coast) or if both will be
in play.

Models are in general agreement that the storm should be clear of
the area sometime late Monday night. The rest of next week is
expected to be followed by an unsettled pattern with humid
conditions and a daily chances for showers and thunderstorms.

Right now, it is advisable to begin preparing for a possible
landfalling storm in SNE - a good reference is
ready.gov/hurricanes. Onset of tropical storm force winds is
most likely first thing Sunday morning, so that is when
preparations need to be complete. Having extra cash on hand, gas
in vehicles, and non-perishable food are recommended if power
is lost for a time.

We can never get lucky with a hurricane 

All of this is minute anyway. 

The only thing that matters is what Henri's strength, position, and movement is by this time tomorrow (actually several hours earlier).

The models could all of a sudden shift the track to Europe...doesn't mean anything.
