# Weather monitoring in your safety plan: how KNMI warnings land in your alerts and logbook automatically — MijnEvent [Home](https://mijnevent.nl/en) / [Blog for event organizers](https://mijnevent.nl/en/blog) / Weather monitoring in your safety plan: how KNMI warnings land in your alerts and logbook automatically safety permit safety plan weather # Weather monitoring in your safety plan: how KNMI warnings land in your alerts and logbook automatically Almost every safety-plan format has a 'weather monitoring' section — and almost nobody fills it in concretely. The Safety & Permit module pulls the KNMI warning code for your event location every hour and turns it into a demonstrable process.

Page through a handful of real safety-plan formats from Dutch safety regions and municipalities, and the same section keeps reappearing: weather monitoring. VGGM asks for it explicitly, including a "point of no return" — the moment sudden weather forces you to make a call. Leeuwarden names the scenario outright. VR IJsselland lists "hazardous weather" among its advisory themes. And almost every plan we come across fills that section with the same line as the crowd-monitoring section: "we keep an eye on the weather." No method, no measurement point — a promise. # Why weather stays a blind spot The problem isn't that organisers ignore the weather. It's that "keeping an eye on it" says nothing about when you act, and records nothing for the moment a safety-region adviser asks about it. Exactly as with attendance figures: a concrete, repeatable process outweighs a well-intentioned statement. See also [our article on the full safety plan](/en/blog/event-safety-plan-crowd-monitoring) for the other sections plans tend to fail on. # How the KNMI integration works The [Safety & Permit module](/en/blog/safety-permit-module-gate-monitoring) automatically pulls the current KNMI warning code every hour for the province where your event takes place — the same public signal published on knmi.nl: green, yellow, orange or red. As soon as the color moves above green, a notification appears in your dashboard, alongside the three other alert types you already know: scan spikes, capacity, and silent gates. The same rules apply: a steward has to confirm it, and that confirmation is recorded immutably — precisely the alert chain a permit reviewer wants to see. The weather picture is logged every hour regardless, even when nothing's wrong. That's not noise: it's the basis for the "point of no return" moment your safety plan asks about. You can later show exactly what KNMI reported at any point in the evening, and when that changed. # Back in your evaluation report After the event, that same weather picture lands in the evaluation report, next to the inflow graph and the incident log. That turns a line like "the peak at 9:40pm coincided with a rain shower" from an anecdote into a statement backed by data. For a municipality reviewing your event afterwards — or for yourself, preparing next year's edition — that's exactly the kind of context a good evaluation needs. # What it is, and isn't Worth being upfront about: this isn't a dedicated weather service, and it doesn't replace professional meteorological advice for a large or higher-risk event. It's KNMI's public warning, automatically tied to where you need it — in your alerts during the event, and in your evidence afterwards. And as with the rest of the module: a human pushes the button. The system signals and records; you decide whether to scale down, shelter visitors, or evacuate. Like every part of the module, this is free and needs no setup: as soon as your event has a province set, the integration runs automatically.

Frequently asked questions ## Frequently asked questions ## Does this replace a professional weather service during my event? No. The integration uses KNMI's public warnings (code yellow/orange/red per province) — the same signal published on knmi.nl. For a large or higher-risk event, a dedicated meteorologist or weather service advising at the venue level remains a useful addition, not a replacement. ## What happens if KNMI is unreachable? Nothing breaks visibly: without the KNMI integration configured, or during an outage, your dashboard keeps working — just without the fourth alert type. No weather data is never a broken dashboard. ## Why a color code per province instead of an exact location forecast? Because that is exactly what KNMI's official warning system provides — the same methodology municipalities and safety regions already know and expect. A custom 'chance of rain' widget would line up less well with what your safety plan needs to substantiate. ## Do I need to configure anything? No. As soon as your event has a province set, the hourly integration runs automatically as long as the module is active — no extra form, no separate toggle.
