MOTORISTS in Lincolnshire have been warned to drive carefully today - after the county is braced for flash freezing.
Today’s rain will instantly freeze this afternoon – meaning salt on the roads will not have time to take full effect.
A flash freeze is when temperatures plummet within 30 minutes of rain stopping, and only happens once or twice a year.
It means motorists are being strongly urged to take extra care and expect icy surfaces, especially into rush-hour.
Full, countywide gritting runs are currently taking place, but the rain washes much of the salt off the surface.
Several further runs, including an extra one for hills, will take place through the remainder of today and into the night.
Darrell Redford, Lincolnshire County Council winter maintenance engineer, said: “As rain washes grit away, it’s normal practice to wait until the rain stops and then treat the roads in readiness for falling temperatures later.
“What we’ll see this afternoon is a flash freeze, meaning those icy temperatures will arrive within 30 minutes of the rain stopping, so we simply won’t be able to get the gritters around everywhere in time.
“We’ll be out in full force, salting the roads constantly as the day and night progress, but it’s absolutely essential that motorists expect icy road surfaces and drive with the greatest of care.
“Likewise, pedestrians should tread extremely carefully.”
The county council is also warning temperatures may reach -9 degrees celsius in some areas, the area where salt starts to become less effective in any case.
