A couple of Americans have remarked to me about BrE speakers' use of grit as a verb in snowy contexts like these (from a single article in the local newspaper):
Hospitals across Sussex were inundated with patients over the weekend who had broken limbs after falling on ungritted pavements. [Ed. note: the weekend broke limbs?]
Dozens of people contacted The Argus to condemn the lack of gritting which has left many elderly people trapped in their homes. [Ed. note: did they also condemn the lack of a comma on a non-restrictive relative clause?]
A Brighton and Hove City Council spokesman said all the authority's refuse and recycling staff were being diverted to gritting roads and pavements today.Now, I don't believe that this use of grit is solely BrE, but in the snowy Northeastern US, one talks about salting the roads--which may include some sand--or less frequently of sanding the roads--which usually includes some salt or other de-icing agent. In addition to sand, ash and cinders are (or at least have been) commonly used. The "sand" that's used may be more coarse material, like the grit used in the UK. And while gritters are used in the UK to spread grit, salters and sanders are used in northern north America for the same thing.
I come from a place where we get to talk about lake-effect snow and (orig. AmE) blizzards a lot.
And when we use the term blizzard back home, we don't mean a piddly 6 cm (2.4 inches) of snow like my local UK paper does. It turns out that the word may be common to AmE and BrE now, but the meaning is not. From Wikipedia:
In the United States, the National Weather Service defines a blizzard as sustained winds or frequent gusts reaching or exceeding 35 mph (56 km/h) which lead to blowing snow and cause visibilities of ¼ mile (or 400 m) or less, lasting for at least 3 hours. Temperature is not taken into consideration when issuing a blizzard warning, but the nature of these storms is such that cold air is often present when the other criteria are met. Temperatures are generally below 0 °C (32 °F).
According to Environment Canada, a winter storm must have winds of 40 km/h (25 mph) or more, have snow or blowing snow, visibility less than 500 feet (150 m), a wind chill of less than −25 °C (−15 °F), and all of these conditions must last for 3 hours or more before the storm can be properly called a blizzard.
Many European countries, such as the UK, have a lower threshold: the Met Office defines a blizzard as "moderate or heavy snow" combined with a mean wind speed of 30 mph (48 km/h) and visibility below 650 feet (200 m).
Of course, even a little snow in a place like southern England (or the southern US, for that matter) grinds the place to a halt. I've had three 'snow days' from work so far this year, and we've never had accumulation of more than a few inches. But not only are snow (AmE) plows/(BrE) ploughs rarer than hen's teeth here, but no one has a (possibly AmE) snow shovel, few have appropriate footwear (attention: (BrE) wellies [AmE: rubber boots] are not snow boots!) and almost no one knows how to drive on icy roads. So, we can't really blame the victims of these snows for their inability to deal with them--though that didn't stop me from less-than-sympathetically exclaiming in response to the laceration on my friend's face and talk of the bruise on another's (BrE) bum: "You people don't know how to walk on snow!" I have since spent every outdoor moment convinced that this comment is going to come and almost-literally bite me on the (AmE) ass/(BrE) arse, landing me with a broken coccyx or worse.
Final reflection: I can't believe that I just had to invent a 'weather' tag for the blog in response to this post. I'm in England! I'm supposed to be talking about the weather at least 74% of the time. I hope they don't find out and revoke my citizenship.
