Heavy snow and blizzard conditions may occur. Snow may mix with or change to sleet or rain late Tuesday morning into Tuesday afternoon. Snow accumulations maybe 12 to 20 inches. The snowfall rates could be two to four inches per hour.
Dangerous whiteout travel conditions could occur at times, with some impassable roads. Winds could be 25 to 35 miles per hour with gusts up to 40 to 55 miles per hour on Tuesday. Highest winds will be across coastal areas like Darien.
