How does your country define “extreme weather”?

r/

Legally or socially, how is “extreme weather” defined in your country? What weather is bad enough to disrupt society?

    Red warning. It signifies extremely severe weather conditions that pose a significant risk to life and property over a wide area. People are advised to take exceptional safety measures, stay indoors, and follow instructions from authorities. Schools shut down etc.

    European windstorms (“Orkan” in german) is probably the most common one here, and really the only thing that occurs regularly.

    Heavy snow is another one, but it rarely happens anymore because of climate change, atleast in my part of the country.

    We don’t have the severe weather like for instance in the USA and almost never power outages during such weather, but sometimes during a heavy thunderstorm hail as big as dove eggs, severe rain fall and regional floods. Not in my part of the Netherlands, but further south where the temperatures are higher, the occasional tornado (class 1) and water spout. Because of global warming the storms are getting more severe though. No hurricanes. Sometimes hurricane class.

    When I was a kid, -25 in winter was normal for January or February. Not for the whole month, but we regularly experienced such temperatures.

    Currently -20 in winter is considered extremely cold, – 15 is exceptionally cold.

    Weather that is supposed to happen once every 10 years, or rare weather that is only occuring every 10.000 years. according to our weather institute

    During winter it’s ”red alarm” if it’s expected to go below -5.

    During summer it’s ”red alarm” if it’s expected to go above +35

    Croatia, Zagreb at least

    Hurricane, snowstorms, heatwave (30+ celsius) or flooding

    Doesnt get too extreme in Denmark tbh but we have had more flooding than usual recently

    Heat wave, meaning at least 3 consecutive nights above 21°C and 3 days above 30°C. At that temperature your body can’t rest

    In England, Low/Medium/High thresholds for heat alerts are max daytime temperatures of 28°/32°/40° in London and 27°/30°/38° in the rest of the country.

    For cold alerts, across all of England, Low is average (not max or min) temperatures below 2° for 48 hours, Medium is average temperatures below 2° for five days or below 0° for 48 hours, High is average temperatures below 0° for for five days or below -2° for 48 hours.

    In Scotland, anything over 15C is considered a danger to life.

    We’re ginger, pale, and some have freckles; the sun is our natural enemy.

    Any other weather is to be expected: rain, wind, snow and ice, are ignored as “the usual”.

    The most disruptive weather pattern which is semi- regularly occurring in Czechia is flooding. The red warning is in this case issued if the floodwaters are expected to reach high enough to require evacuations of low-lying houses. For each measuring station along Czech rivers, there are specific water flow rates defined which will cause the warning to be issued for their area if exceeded.

    For temperatures, red warning means that the maximum temperatures will rise over 37°C or minimum temperatures will fall under -24°C, and for winds, if the speeds exceed 30 m/s in lowlands or 45 m/s in the mountains.

    honestly, nothing

    like we have the occasional once in a 100 year local floods or mudstreams but otherwise nothing

    there’s no regular phenomenom that disrupts civil live, sure people will say that first frost can make the road slippy and it does but that’s expected, people will complain that the trains get to a halt because of leaves falling but that’s also expected

    on the average, we simply can keep on going and I think that’s our greatest strength

    extreme weather would be a sudden cold so the salt-sprayers haven’t had a chance to go out or so warm that the civil brigade has to go out and distribute water to the elderly and the fire brigade is on high alert for forest fires if that answers your question

    in Ukraine it was –20 / +30, which meant no school days. now +30 is ignored bc heatwaves and –20 is rare
