This is from Jim's Email this morning about the Gribbs for the LongPac:

send grib:36N,38N,120W,127W|.5,.5|0,3..360|PRMSL,WIND
send COAMPS:38N,36N,127W,122W|.2,.2|0,3..72|PRMSL,WIND

First – this assumes you have a Windows PS… and not a Mac…
Get and install the grib viewer at-
http://www.siriuscyber.net/wxfax/

You want to install the old viewer “Viewfax cer 4.3.4” (do not install the new “beta” Viewer ver 5.0.056 as most people find it won’t allow you to draw the red line on your proposed rhumb line). Note you can quickly scan through the weather over time using your keyboard’s “down arrow” (if you hold the down arrow down, you get a weather animation of sorts).

Then just submit the two attached emails.
One email is for the “COAMPS” forecast – which is the best forecast for “near shore”, has finer resolution, (.2 degree) – but only goes out 72 hours at best (and frequently just 48 hours)
The other email gets you the GFC forecast – which is better in deep ocean (out beyond 100 miles), has coarser resolution (.5 degree) – and goes out 15 days (don’t trust it past 4-5 days)
You’ll get a response email back in under one minute – you can just double click the attached grib file to open in the Viewer.

Last…

You can learn more about how to tweak these grib request emails - such as to get a larger patch of ocean (something you’ll want if planning your route for the SH Transpac) at –

From the saildoc info at the link above:

To request a GRIB file send an eail to query@saildocs.com, Type anything you wish as subject - but do not leave it blank.

A simple message reads

send gfs:40N,60N,0W,20W/0.5,0.5/0,24,48,72/

That will result in an email with a GRIb file attached that gives Wnd and Pressure values for the area selected, on a 0.5 degree latitude/longitude grid at 0, 24, 48 and 72 hours ahead.
