NGA Nav Pubs

The NGA pubs link has a history of wandering around, hence we make a shortcut. Also transient security issues at the link often blocks entry

If the link does not work, try another browser (Firefox seems most robust for this one) or check our article on this link.

Ironic to go to a Navy site and be told the site is not safe! These are glitches, not security issues.

This link is not consistent with the others; it is also in our marine weather links, but it is too important and it seems maybe too over looked, so we have to stress it whenever we can. We have this archived, so if the link goes missing, let us know. Tropical storm safety and the Mariner's 1-2-3 Rule
Since we are not being consistent, here are a couple more links from our weather resources.
