Snow squall warning

These will reduce visibility to less than 1 km and produce large accumulations of snow on the ground along narrow corridors in lee of the waters.

Frontal snow squalls are associated with a fast moving intense cold front in winter.

Quantities of snow is not important with this type but intensity is heavy for a short period, typically 10 to 20 minutes.
