Brief Description	Yellow Warning - Flash Freeze -
Detailed Description	A rapid drop in temperature will cause wet or slushy surfaces to suddenly freeze. Locations: Portions of southern Manitoba. Time span: This morning through to this evening. Remarks: After mild temperatures and some rainfall with melting snow, a strong cold front will bring a very rapid drop in temperatures beginning this morning over southwestern Manitoba, and by this evening over the Red River Valley and southeastern Manitoba. ### Roads and walkways may quickly become icy and slippery. Flash freeze warnings are issued when temperatures are expected to rapidly drop below zero, causing water from rain or melted snow to quickly freeze on streets and sidewalks.
