# Currently - 
#     torn ranges 0 - 6  (F-scale)
#     hail ranges 0 - 8  (inches)
#     wind ranges 30 - 131  (knots)
# After conversion of wind knots to force
#     wind force will be in range 0 - 12
#     torn ranges 0 - 6
#     hail ranges 0 - 8
# LCM of the three highs are 48. So let's base our scale factors on that.
# Scale factors : Torn: 8, Wind: 4, Hail: 6
