Not on the public site: 6 of 7 card fields read 'not computable' here, and on every place more than half do.

Mumbai city · mumbai

lon 72.94000, lat 19.10000 · 1 km MGRS cell 43QBB8313

ingest/geocode.py: "Nominatim geocodes to a place, so precision is place-level (~3 km), never a street fix." The lon/lat above is a named-place point, not an address; the card describes its 1 km cell.

This-week probability not computable — no forecast is published for mumbai (site/public/data/forecast/ holds only the AOIs with a training panel) — not modelled, not safe
Band not computable — no forecast is published for mumbai (site/public/data/forecast/ holds only the AOIs with a training panel) — not modelled, not safe
Top reasons not computable — no mapped waterlogging hotspot lies in cell 43QBB8313 — of the 9 mumbai hotspots, none is in this 1 km cell (nearest: Kurla LBS Marg, 6.31 km away in cell 43QBB7711; its reasons describe that spot, not this cell)
Relative risk (within city) 0.418 · above 79% of the 1288 boxes in this city — relative susceptibility within this city (0-1, quantile-banded), not a probability and not comparable between cities
Return period (RSK-06) not computable — 4 usable annual maxima (< 5, RSK-06 STOP IF): years [2017, 2019, 2020, 2021] over a 5-year span
Depth, 1-in-10 yr not computable — no depth layer exists: RSK-09's loss cards (site/public/data/loss_cards/) were never produced (deferred) and the HAND depth layer failed its own gate (HYD-08 STOP IF, EVALUATION.md)
Depth, 1-in-50 yr not computable — no depth layer exists: RSK-09's loss cards (site/public/data/loss_cards/) were never produced (deferred) and the HAND depth layer failed its own gate (HYD-08 STOP IF, EVALUATION.md); and the record cannot support it anyway: no return period rarer than about 1-in-(n+1) years is computable from 4-5 dated events per AOI (RSK-02 STOP IF, EVALUATION.md 'Return-period frequency — record adequacy')
Depth, 1-in-100 yr not computable — no depth layer exists: RSK-09's loss cards (site/public/data/loss_cards/) were never produced (deferred) and the HAND depth layer failed its own gate (HYD-08 STOP IF, EVALUATION.md); and the record cannot support it anyway: no return period rarer than about 1-in-(n+1) years is computable from 4-5 dated events per AOI (RSK-02 STOP IF, EVALUATION.md 'Return-period frequency — record adequacy')
  • This is a per-cell card, not a per-address one: geocoding is place-level (~3 km) and the grid coarsens to 1 km.
  • The 'why' reasons come from a street-waterlogging relative ranking, not a probability — results/<city>_why.json labels itself that way and the card must repeat it.
  • The probability is the climatology baseline over 28 cells in 2 cities unless is_learned is true; a cell not in the panel is 'not modelled', not 'safe'.
  • Depth rows read 'not computable' until the HYD depth layer passes its own gate — they are not zero.
