The 50 knot, 120 hour cumulative wind speed probabilities show

probabilites of sustained (1-minute average) surface (10-meter altitude)

wind speeds equal to or exceeding 50 kt...57.6 mph

(50-knot force) at a regualary spaced (1/2 degree) grid of points. The

cumulative periods begin at the start of the forecat period and extend through

the entire 5-day forecast period from 0-120 hours.
