Discovered this website WXTiles | Weather overlays for GoogleMaps and OpenLayers
that has free kml downloads for google earth
showing a host of current
and forecast weather
information for the entire world. Being a passage
making newbie, but with all that about to change very soon, this looks like a great tool for at least studying world weather
patterns for dummies and maybe even as a tool for passage
planning (Internet bandwidth permitting, of course).
P.s. I have no affiliation with the above site whatsoever, it just looks like a cool use of google earth
from a cruising perspective.
