The Glass: Read the Glass. Record the Call.

A tropical storm is approaching. The marina manager has to decide whether to call a haul-out. The port authority has to decide whether to suspend crane operations. The resort manager has to decide whether to relocate guests. The night-shift watchkeeper has to decide whether to escalate.

Each of them is looking at the same NHC cone — a single line from a single model showing where the storm might go. The cone is useful. It is also one perspective on a fifty-member ensemble that tells a much richer story about uncertainty, probability, and the range of outcomes the cone compresses into a single boundary.

The Glass shows the full picture. And then it records the call.

What The Glass is

The Glass is a browser-based storm decision desk. It is not a warning. It is not a forecast. It is a decision rehearsal instrument that combines multiple forecast sources, visualises uncertainty, and seals every decision in a hash-chained evidence pack.

The name comes from the barometer — the glass that sailors read before the storm arrives. Read the glass. Record the call.

Four dimensions of a storm

The Glass organises forecast information into four visualisation layers, each answering a different question:

The spread is the forecast

Fifty ensemble member tracks rendered on a 3D globe, coloured by wind intensity — tropical storm, category 1–2, major hurricane. The spread of the ensemble is the forecast: where the members agree, confidence is high. Where they diverge, uncertainty is real. A single best-track line hides this information. The Glass shows it.

The cone — and the model that is beating it

The official NHC cone (approximated two-thirds probability circles) alongside a Google DeepMind AI track overlay in rose. The gap between the two is measured in nautical miles. When the AI model consistently outperforms the official guidance, the operator needs to see both — not choose one.

Risk as terrain

Probability columns showing 34-knot, 50-knot, and 64-knot wind coverage areas. A valid-time scrubber lets the operator move through the forecast timeline and watch how probability evolves. Hover interactions reveal exact percentages. This is not a map with a cone on it — it is a terrain of risk that changes shape as the storm develops.

When the forecast was made

Issuance cycle navigation — T-72, T-48, T-24, now — showing how prior forecast runs compare to the current one. Prior runs rendered as slate ghosts. Historical scoring against actual tracks. The operator who can see how the forecast has changed over three days makes a better decision than the operator who sees only the latest advisory.

Four personas, four decision types

The Glass is designed for four people who make different decisions about the same storm:

Marina — haul-out decisions. When do boats come out of the water? The threshold is wind speed, but the decision is timing: haul-out takes time, and starting too late means finishing in the storm.

Port — crane suspension. When do the cranes stop? Container operations have hard wind limits, but the cost of early suspension is measured in vessels waiting at anchor.

People — guest and vessel relocation. When do the guests move? When do the vessels relocate? The threshold is not just wind — it is lead time for safe transit.

Watch — night-shift thresholds. When does the watchkeeper escalate to the day team? The night shift sees the forecast update that arrives at 3 AM. The decision to wake the decision-maker is itself a decision that needs a threshold and a record.

Each persona has site-specific wind thresholds and rule-based triggers. The rules are sealed in the genesis block of the hash chain before the storm arrives.

The record that survives the storm

Every decision made in The Glass is sealed in a SHA-256 hash-chained evidence pack:

Genesis block — the rules. Wind thresholds, trigger conditions, escalation criteria. Sealed before the storm. Immutable.

Snapshot blocks — the forecast state. Which ensemble members were active, what the probability terrain showed, what the NHC advisory said, what the AI model predicted. Captured at each decision point.

Decision blocks — the actions. What was decided, by whom, based on which snapshot, with what probability data. Sealed over the prior blocks.

When the insurance adjuster arrives after the storm and asks "what did you know and when did you know it?", The Glass produces the hash chain. The decision, the forecast state that informed it, and the rules that triggered it — all linked, all timestamped, all verifiable.

Three real 2026 storms

The Glass includes three real storms from the 2026 Atlantic season — POLO, NOLO, and FAY — sourced from NHC a-deck data as of 28 September 2026. These are not synthetic scenarios. They are live forecast data rendered through the same visualisation and decision framework.

Hurricane VESPER on the New York Bight is the synthetic training scenario — a fabricated storm on real geography for decision rehearsal without waiting for an actual event.

Why this product exists in this portfolio

The Glass applies the same thesis that runs through BLACKBOX, Bulwark, and Plimsoll: if you cannot reconstruct the decision after the event, you did not govern it.

BLACKBOX records what AI agents do. Bulwark enforces guardrails at runtime. Plimsoll classifies AI systems for banking. The Glass records what human operators decide when a storm is approaching.

The hash chain architecture is identical. The evidence standard is identical. The domain is different. The principle is the same: the decision must survive the event that tested it.

The Glass is live and free to use.
