A ship’s-log reading of Great Lakes weather
The log translates the official forecast. It does not replace a warning, a GLF, or a harbor master who knows the bar.
Six levels, the same science Echo and the woods use, written as a lake would keep them:
Each mark carries a number, a name, a plate in the log, a remark from the keeper or captain, orders for the watch, and the official NWS language it stands in for.

The keeper — has the lamp trimmed and nothing particular to report
Walk the pier if you like. Mind the spray anyway — habit is cheaper than regret.
“A still fetch. The breakwater took the morning without complaint.”

The deckhand — watches the chop and pretends not to
Small boats keep an eye on the sky. Hats stay on. Plans may still proceed.
“A short steep lump off the harbor mouth. Nothing a sensible boat cannot abide.”

The captain — has already looked twice at the glass
Small craft stay in, or go with someone who knows the bar. Allow extra time along the shore.
“Whitecaps in the open. The harbor looks more intelligent than it did at breakfast.”

The keeper — keeps the log in a firmer hand
Stay off the open water. Secure what can blow. Check again after the next watch.
“The lake has dropped the pretense of manners. The light is for more than courtesy now.”

The captain — means the harbor, and does not mean later
Ashore. Inland of the spray. Follow official instruction without debate.
“No one argues with a sea like this. The walls that matter are the ones already around you.”

The captain — will not take the next watch as an answer
Get off the water and off the open shore. Innermost room, away from windows. Do exactly what the officials say.
“There is only the nearest solid ground, the lowest room, and staying put until someone official says otherwise.”
The large remark and the illustration at the top of the live log follow the level. The quote under orders follows the weather itself — wind, rain, and notices on the board.
Keep a weather eye. Trouble may make up on this fetch.
Prepare. Stay informed. Small craft think twice.
All hands below. The danger is happening or standing in.
Take protective action now. Seek the harbor.
The log will say it in lake talk. The badge still says Watch or Warning in the official tongue. Believe the badge.
The log uses the old working words so a remark means something on the water. If a line is strange, this is the lexicon.
| Word | What it means here |
|---|---|
| The glass | The barometer. A falling glass means trouble is making up. |
| Fetch | How far the wind has to work on the water. A long fetch builds a larger sea. |
| The bar | The shallow water at a harbor mouth, where a short steep sea can stand up. |
| Lump / chop | A short, steep sea. Uncomfortable, not yet a gale. |
| Small craft | Boats that feel a Small Craft Advisory first — open boats, daysailers, tenders. |
| Watch | A four-hour trick of duty, and also NWS language: conditions may become hazardous. |
| Weather eye | Keep looking. The lake changes its mind without asking. |
| Lee | The sheltered side. Seek the lee of the land, not the open fetch. |
| All hands below | Off the deck. Ashore. The lake is no longer a place of work. |
| GLF | The NWS Great Lakes forecast. Echo still has the full product when you need the fine print. |
| Level | Water | Sky | Who speaks | Tone |
|---|---|---|---|---|
| 0 | Still fetch | Fair | The keeper | Lamp trimmed |
| 1 | A lump / chop | Making up | Deckhand or keeper | Weather eye |
| 2 | Whitecaps, bar muttering | Wind on the fetch | The captain | Small craft in |
| 3 | Gale building | Spray over the wall | The keeper | Firm hand in the book |
| 4 | Open lake a mistake | Storm-dark | The captain | All hands below |
| 5 | No second harbor | Destructive | The captain | An order, not a remark |
The live page uses these cards, in this order. Numbers change with your station; this is a static example at Level 2.
Lake Michigan — Your station
The wind has found the fetch, and the fetch is answering.
Whitecaps in the open. The harbor looks more intelligent than it did at breakfast.
The captain — has already looked twice at the glass

This morning: Begins as Fine for the Breakwater (Level 0). The keeper — has the lamp trimmed and nothing particular to report.
This afternoon: May become Small Craft, If You Please (Level 2). The captain — has already looked twice at the glass.
Small craft stay in, or go with someone who knows the bar. Allow extra time along the shore.
The captain logs: “The harbor is still there. Use it.”
Log the time. A remark without a time is a rumor.
