Brockville – Temperatures are forecast to fall rapidly. Ponding water, slush, and any falling precipitation will freeze as the temperature drops.
Icy conditions late this afternoon into this evening.
Following the passage of a cold front this afternoon, rain will change to snow and there will be a hard freeze as temperatures plummet. There may also be a brief period of freezing rain during the changeover from rain to snow.
Surfaces such as highways, roads, walkways and parking lots will become icy, slippery and hazardous. There may be a significant impact on rush hour traffic in urban areas.
Flash freeze warnings are issued when a rapid drop in temperature is expected, that can cause water from rain or melted snow on streets and sidewalks to quickly freeze.
