Up to High likelihood
Properties in HU17 5QA sit in the Environment Agency's High flood-likelihood band (worst property). The band is the worst found in the postcode — it describes the land around properties (defence-adjusted, rivers & sea), not any single address, and not today's conditions.
| Likelihood band | Annual chance | Properties | Of which homes |
|---|---|---|---|
| High | greater than 3.3% | 32 | 30 |
| Medium | 1% – 3.3% | 3 | 3 |
| Low | 0.1% – 1% | 6 | 5 |
| Very low | below 0.1% | 2 | 1 |
Over a 25-year mortgage, a property in a high-likelihood area has at least a 57% chance of flooding at least once.
HU17 5QA gets about 660 mm of rain a year on average (wettest month November, 66 mm; driest March, 40 mm). That is 43% drier than the UK as a whole, which averages 1,163 mm a year.
A thirty-year average for the surrounding area, not a measurement at this address and not a flood risk on its own: a dry area floods when a storm sits over it, and a wet one may drain away perfectly well.

The map above shows the real EA rivers & sea likelihood cells around HU17 5QA. The small panels are illustrative previews of the report's per-layer map views — the full report draws each layer for real, plus recorded extents, defences and a building picker on an interactive map.
Warnings cover flood areas, not individual addresses.
| Date | Mapped flood extent | Approx. distance |
|---|---|---|
| Feb 2020 | 2020 February Flood Incident - Storm Dennis | ~44.8 km |
| Feb 2020 | 2020 February Flood Incident - Storm Ciara | ~53.0 km |
| Nov 2019 | 2019 November Flood Incident | ~70.4 km |
| Mar 2018 | 2018 Apr-River Hull. Froddingham (Old Howe) Breach | ~5.3 km |
| Jun 2007 | June 2007 Flood Event (Hull and East Riding) | ~8.7 km |
These are extents the Environment Agency has mapped, not a list of every flood. Records, not floods: no outline on the record is not evidence a place has not flooded. The full report tests whether any extent covered the exact spot.
