Atlas. Catastrophe risk, on the map.

A map-first way to read catastrophe risk. The current public sample compares historical and warming-storyline footprints for UK Storm Eunice. Switch between 48 h rainfall change and peak 10 m wind change to see where the event footprint changes.

The idea

Risk is not a row in a table. It is a place on a map.

Most catastrophe output arrives as a single loss number for a portfolio. That hides the thing a decision actually turns on: where the hazard lands, how far it reaches, and which assets sit inside the footprint.

Atlas is map-first. In the current public sample, Storm Eunice appears as two change-footprint layers: 48 h rainfall and peak 10 m wind. Each compares the historical run with a warming storyline on the same MPAS fields and domain.

The risk map

One storm, two footprints, layer by layer.

This UK Storm Eunice sample compares historical and warming-storyline change footprints. Pick a layer and read the footprint against its scale.

From map to readout

Each footprint carries a documented event readout.

The public sample reports only the Eunice values available from the two published footprints. Rainfall carries a maximum absolute change and a relative change in the rain maximum; wind carries the peak 10 m wind change. These are event-footprint values, not per-region or asset-level scores.

The demo

A narrow public sample. Honest about what is modelled today.

Current sample · Storm EuniceThe public sample maps PGW vs HIST change for 48 h rainfall and peak 10 m wind.
Comparison, not forecastThe public maps compare one past storm under historical and warming storylines. They do not forecast a specific future event.

// note: Atlas currently presents Storm Eunice as two PGW vs HIST change footprints: 48 h rainfall and peak 10 m wind. These are physics-based warming-storyline stress tests of a past storm, not forecasts of a specific future event. Public samples are illustrative validation evidence from past storms, not a live hazard service. Roadmap layers carry no result figures until they are modelled.
