Winter delivered a wallop to the Capital Region 20 years ago this week. It was the blizzard of 1993 — a nor’easter that dropped 26.6 inches of snow in the middle of March. The storm was a deadly event. Four people lost their lives. Snow began to swirl around dawn on Saturday, March 13 and quickly covered bare grass and dry pavement. Winds showed up. So did tall drifts. “It’s definitely the most powerful storm to strike the region in decades,” said meteorologist Anthony Cristaldi at the National Weather Service in Albany. “This is like a hurricane with snow,” said Devlin Dean, a forecaster at the Atmospheric Science Research Center at the University at Albany, as he watched the snow fall.
