First Look at Next Saturday's Weather

Lock 6, Erie Canal
No LL

It's still 5 days away so forecasts aren't terribly accurate. Notwithstanding that, winds look favorable for a passage from New York to Norfolk. See below from http://www.passageweather.com/


How to read wind barbs: The barb points the direction the wind blows. Each long feather on the barb is 10 knots of wind, each short feather is 5 knots.

  1. I always thought the "arrow" pointed into the direction of the wind, but maybe that's what you're saying just in a different way.

    The way I read it is if someone had thrown an arrow that went along with the wind. So the arrow's tip is travelling in the same direction as the wind, and the "barb" is pointing towards where the wind is coming from.

    So... SW winds for your passage.

    Or... has it been so long that I have it backwards? Gad, I'd better get back out there!

  2. Sorry R. You did get it backwards, the winds shown in the picture are NW.

  3. Proof: It HAS been too long.

    I guess I would have figured it out pretty quickly in real life :D Have a great passage!

  4. Sorry to belabor the point, but I see what happened. I just read "the barb points into the wind" as meaning the opposite, for some odd reason, and THEN misread what area of the coast the chart was showing.

    I just think of it as the wind moves as the arrow would (i.e. enters the arrow at the barb and exits the arrow at the tip), which is the same thing in the end.

    Then I mistook the Chesapeake for something else -- hello!), so I now see the winds up near NYC as being NW. Nice forecast for your passage :)
