NTC = %
NS = Named Storms (# storms with winds >=35kts) NSD = Named Storm Days (# days with NS present) H = Hurricanes (# storms with winds >=65kts) HD = (# days with H present) IH = Intense Hurricanes (# storms with winds >=100kts) IHD = Intense Hurricane Days (# days with IH present) Ave __ = 1950-2000 average of the above parameters

Either load values from a previous season [yellow area] and
see its NTC by clicking the circle by that year, OR
Enter your own values in the boxes [blue area] and press
Calculate to see the NTC.

If you've already got values loaded into the cells and wish
to start over, click the circle next to Custom.
You can change any value at any time and recalculate the
NTC. Average values are pre-defined but can also be
altered if desired. This is useful to see "what
happens to the NTC if there were 14 fewer NSD", for example.
