Official Weather Warnings
Official warnings from Europe, the United States and Canada.
Official weather warnings for your place, as the national services publish them: Europe, United States and Canada, with the level, the area and the hours.

All Weather & environment tools →A storm is announced, the sky turns, and you want to know what the weather service of your country has actually declared — not what a headline says about it. Pick your place: the page shows the warnings in force, each with its colour, the hazard it names, the areas it covers and the hours it runs. Below each one sits the text of the service itself, word for word, in the language it publishes: we never translate a warning, because reproducing it unchanged is exactly what Environment and Climate Change Canada, the National Weather Service and MeteoAlarm each require. Europe is read through MeteoAlarm, the shared service of the European weather services; the United States through the National Weather Service; Canada through its national service. Everywhere else, the page says so plainly instead of showing an empty list that would look like calm weather.
How to use it
- In “Country”, keep the suggested country or pick another, then type the first letters of your town in “Town or city” and click the right line; “Use my location” takes your position instead, rounded in your browser before anything is sent.
- The “Your place” tab lists what is in force. A coloured square carries the hazard drawing, then come the hazard and its level, the areas named by the service, and the start and end times in the time zone of the place.
- Read the paragraph below the line: it is the service's own text. A short sentence above it names the language it was published in and the office that issued it, so you always know whose words you are reading.
- The “By country” tab shows the national picture of one of the thirteen European countries read here — useful before a drive or a flight. The United States and Canada are not in that list: their services answer for a point and for an area, so they are read through the place instead.
- When nothing is listed, read the sentence above the list before concluding anything: it says whether a service was actually read for this country, or whether none is covered here yet.
Where the warnings come from
The country you are in decides which service is asked, because none of the three covers another's territory and there is nothing to merge. In Europe the page reads MeteoAlarm, run by EUMETNET, the network of European weather services: a national feed lists what is in force, and the detailed document of each warning carries the text in up to eight languages. In the United States the National Weather Service answers for the exact point. In Canada the service of Environment and Climate Change Canada answers for a box of about 55 km around the point, and warnings marked as ended are dropped before anything is shown.
What we translate is only the coded part: the kind of hazard, the level from green to red, the times and the names of the areas. Everything a forecaster wrote stays untouched. The drawings next to each hazard are ours too — the pictograms of MeteoAlarm and the emblem of the American service are not licensed for reuse, and an official emblem on a page that is not official would suggest an endorsement nobody gave.
When this page helps
- Before driving across a region: the “By country” tab shows every warning in force, so you see the storm sitting on the middle of the route and not only the one over your own town.
- Checking what was really issued, when a message going round says a red warning has been declared: the level and the hours come from the service, and its own sentence is right there under them.
- Following the weather where someone you care about lives, in a country whose language you don't read: the hazard and the level are in your own, while the official sentence stays in theirs.
- Deciding about an outdoor day — a hike, a match, a market stall — where the useful figure is the hour a warning starts, not the word “storm” alone.
What a real reading looks like
On 16 September 2026 at 09:56 UTC, the French feed weighed 11,713 bytes and held seven entries, which came down to two distinct warnings once the entries pointing at the same identifier were merged. The same morning, the German feed weighed 690,422 bytes and held 448 entries pointing at 99 detailed documents: the page reads at most eight of them, the ones that concern the place asked about, because reading ninety-nine documents to draw one screen would be rude to a free service and slow for you.
Inside one of those German documents, a single area carries two codes at once — an EMMA identifier such as DE359 and a warning-cell number such as 116051000 — and no outline at all. That is why Europe is shown country-wide here rather than filtered to your town: the message says which cell it concerns, never where that cell is, and drawing it needs a separate map that the services publish elsewhere.
What this page cannot tell you
- It never warns you by itself. Nothing is pushed, nothing rings: the list is what was in force at the moment it was read, and the reading time is written under it.
- In Europe it shows the country, not your street. A warning covering one valley appears for the whole country, and one covering the whole country looks exactly the same here.
- An empty list is not a promise of calm. It means either that a service was read and had nothing in force, or that no service is read for that country yet — and the sentence above the list tells you which of the two it is.
- The authority is the service, not this page. If what you read here and what your national service publishes ever differ, the service is right: each warning carries a link to its own page.
Privacy
Processed on a serverThe place you choose goes to our server rounded to a hundredth of a degree, about 1 km, together with its country code; your position is asked for only when you click “Use my location”, rounded in your browser and never kept. Depending on that country, our server asks MeteoAlarm, the National Weather Service or Environment and Climate Change Canada: each of them sees our server's address, never yours. The last town you picked stays in your browser's local storage (allin_tools), shared with the weather forecast. To prevent abuse, a counter keeps a fingerprint derived from your IP address rather than the address itself. The delivery network keeps a reading for a few minutes at most — four for MeteoAlarm, one for the American service, five for the Canadian one — and nothing is logged. Usage measurement records that warnings were shown or that a reading failed, never the place.
Frequently asked questions
Why is the warning text not in my language?
Because translating it is forbidden, and for a good reason. Environment and Climate Change Canada requires its information to be reproduced without altering the content or the intent; the National Weather Service forbids presenting a modified version as official; MeteoAlarm requires the original to travel with anything derived from it. A machine translation of “take shelter” that lands slightly wrong is a safety problem, not a convenience problem. The hazard, the level and the times are translated, since those are codes; the prose stays as written, and the page names the language it is in.
Nothing is listed. Does that mean I'm safe?
It means one of two different things, and the sentence above the list says which. Either a service was read and had no warning in force — the honest good news — or no official service is read for that country here, in which case the emptiness says nothing at all about the sky and you should go to your national service. The page refuses to let those two look alike, because a silent screen that means “we don't know” is the most dangerous screen a warnings page can show.
Why does Europe show the whole country instead of my town?
Because the European messages identify their area by a code — a region number or a warning-cell number — and carry no outline. Turning a code into “is my town inside it?” needs the map of those cells, published separately by each country, under its own licence. Until those outlines are in place, showing the country and saying so is the only truthful option; the American service, which answers for a point, is filtered exactly.
How old is what I'm reading?
Of a few minutes at most, and the exact reading time is written under the list, next to the name of the service. A reading is reused for four minutes for MeteoAlarm, whose licence requires an average freshness under five, for one minute for the American service and for five for the Canadian one. A tab left open refreshes itself on the same rhythm, but only while it is the tab you are looking at.
What do the colours mean?
They are the four steps of the European scale: green for no particular danger, yellow for weather that calls for attention, orange for a dangerous situation, red for a very dangerous one. The colour says how severe the situation is expected to be for the area as a whole, not how certain it is, and it is set by the national forecaster — the same hazard can be yellow on one side of a border and orange on the other, because the thresholds are national.
Which countries are read here?
Thirteen European countries whose feed was checked one by one — Andorra, Austria, Belgium, Germany, Ireland, Italy, Luxembourg, the Netherlands, Portugal, Spain, Switzerland, the United Kingdom and France — plus the United States and Canada through their own services. MeteoAlarm relays thirty-nine countries in all, and the others can be added the day their feed is verified in turn; a country outside the list is announced as such, never shown as calm.
Does my position leave my browser?
Only rounded, and only if you ask for it. Clicking “Use my location” rounds your coordinates to a hundredth of a degree in the browser, about a kilometre, before our server ever sees them, and that rounded point is never stored. The weather services themselves never see it at all in Europe, since the feed is national; the American service receives the rounded point, and the Canadian one a box around it. Neither ever receives your address.
