Huracán LindaSeptember 13, 1997
This visible image shows Linda at 1630 UTC September 13, 1997. There are signs of weakening from its peak intensity of 185 mph. Notice the small eye is still present, but it is less well defined. There is a "moat" of lower clouds wrapped three-quarters around the eye between the eyewall and convection further from the center. This appears to be a case of concentric eyewalls, with the inner eyewall weakening as the outer eyewall develops around it.

Si estudiamos la escala Escala Saffir-Simpson de ciclones:
Tropical Cyclone Windspeed Scale
Strength Category 1 Minute Maximum Sustained Winds
knots mph km/hr
Tropical Depression TD <34 <39 <63
Tropical Storm TS 34-63 39-73 63-118
Hurricane Cat 1 64-82 74-95 119-153
Hurricane Cat 2 83-95 96-110 154-177
Intense Hurricane Cat 3 96-113 111-130 178-210
Intense Hurricane Cat 4 114-135 131-155 211-250
Intense Hurricane Cat 5 >135 >155 >250
1 --> 82-64 = 18 kt
2 --> 95-83 = 12 kt
3 --> 113-96 = 17 kt
4 --> 135-114 = 21 kt
5 --> Y - 136 = X kt
Supongamos X = 24 kt -->
Y = 160 ktLa escala Saffir-Simpson no es lineal, pero casi, por lo que intuitivamente la podríamos seguir.
No parece muy lógico quedarse con la categoría 5, ya que no tendría la misma fuera unos 161 kt (300 km/h) que unos 136 kt (250 km/h), aunque tampoco se difiere mucho. Pero imaginemso que se llegara a 170 kt o más...
En definitiva propondría al menso una categoría más, la 6
