I've gotten about five inches in Sanford and it's still snowing.
I don't think I'll get the foot or more I always hope for...
That would prove to be crippling for the area considering that the weather won't warm up until Sunday/Monday. I mean, we get 2"-3" and everything shuts down for at least as many days, I couldn't imagine what a foot would do.
They brined the hell out of my street and it's completely covered.
Since my 10pm post the roads are covered here as well. Still less than an inch.
The brine treatment up north last week allowed for complete cover but quick melting afterwards, I don't think they did any plowing as they only got 3-4" and the roads were clear hours later or the next day. It was colder there than here.
It looks like the kind of thing that's white for a few hours then melts or turns to slush, hopefully not to black ice.
Ditto. It stayed wet for a whopping 20 or 30 minutes and was then covered. Makes me wonder how useful brine really is.
The brine doesn't prevent snow cover........it just prevents the roads from icing up which is much worse driving wise than snow. It's pretty much rock salt in liquid form - you throw it on your sidewalk and it's still going to be covered by snow but it's not going to turn to ice.

That doesn't make sense to me...if fluffy snow can survive on top of brine, why can't ice? Rock salt melts snow.

The brine lowers the freezing point of the pavement. I think rock salt lowers the freezing point of water to 25 degrees and brine to much lower temperatures (Google says -6 degrees?). So if the temperature stays above that freezing point, the snow that is on the brined roads won't turn to ice.
Lowers the freezing temperature of water to about 18 degrees Fahrenheit (8 degrees below Celsius)
Prevents snow and ice from bonding with the road's surface
Keeps snow from being compacted by traffic, which can turn it into ice
Is more effective and coats roadways better than plain salt or sand
Gives crews time, since brining can occur up to 48 hours prior to a storm
Costs 15 cents per gallon to produce. One mile of a single lane of road can be treated for about $6; rock salt costs about $14.38 to treat the same stretch of road.

It still doesn't make sense to me, but I'll take your word for it since I know you know more about this stuff.
But if ice can't form, how can snow remain unmelted?
