The map
The map locates the most affected cities in Belgium (at most 10). Where several dots touch, the event is widespread; an isolated dot means a local event, caused by terrain or by a nearby lake or sea.
Historical context
No long climate series is attached to this phenomenon for Sainte-Ode: no nearby official station provides a comparable daily record in this site's data. The comparison is therefore limited to the city's 1991–2020 normal where one exists. A historical rank is shown only when a nearby reference station can place the value, rather than an invented ranking.
In Sainte-Ode, the 1991–2020 normal monthly total for November is 85 mm; the one-day rain forecast is 65% of it.
What it means
One millimetre of rain is one litre of water per square metre: 55 mm means 55 litres on every square metre of Sainte-Ode in a day. The local threshold of 50 mm comes from the estimated daily 95th percentile of the nearest reference station, with a floor of 30 mm, or is a fixed 50 mm when no station is close; crossing it does not mean a flood, but soil and rivers then have little margin.
What to do
- Stay away from riverbanks, underpasses and basements during the rain peaks: water rises faster than you think.
- Clear gutters, drains and gullies in front of your home before the episode, and move valuables off the ground floor and out of the cellar.
- Never cross a flooded road on foot or by car: 30 cm of water is enough to destabilise a vehicle. Check river levels if your municipality publishes them.

Method and limits
The figures in this article are computed automatically from the Open-Meteo forecasts for the cities tracked by weer-meteo.be. An article is written only if a precise threshold is crossed (a 24-hour rainfall above the 95th percentile of the nearest reference station (fixed threshold of 50 mm without a reference series, never below 30 mm)), at most 2 times a week per country, and never twice for the same event. Forecasts are recomputed three times a day, so an event can be spotted up to eight hours late. A forecast is not a measurement and does not replace official warnings: check the official warnings (IRM / KMI) before any decision.
