## Can roads be icy above freezing?

Once the surface reaches freezing ice will accumulate on all road surfaces. If precipitation is falling as sleet or snow road surfaces will begin to cool since the melting process absorbs latent heat. If the wintry precipitation is heavy enough it CAN accumulate on road surfaces that are above freezing.

## Which roadways freeze first when wet?

Bridges and overpasses tend to freeze before the rest of the road does.

## Will rain freeze at 34 degrees?

## Why does water freeze above 32 degrees?

## Can it rain below 30 degrees?

The local weather report only gives us the ground-level temperature. … As it falls it may travel through a layer of air that has a temperature greater than 32 F (0 C). This layer melts the snow into rain. If the temperature at ground level is below freezing then the water may refreeze in the air and we get sleet.

## Will moving water freeze at 32?
