maximum 1-minute wind speed of the tropical cyclone

The table shows the probability that the maximum 1-minute wind speed of the tropical cyclone will be within any of eight intensity ranges during the next 72 hours. It is based on the outcomes of similar NHC wind speed forecasts during the period 1988-1997. The data base excludes unnamed tropical depressions. NA indicates data not available. TF indicates too few (<10) similar forecasts during 1988-1997 to yield reliable results. Wind speed probability table
