Same View as the figure above for past 50 years, Category 3 and above storms. This is the recurrence interval that might constitute the outer reaches of a communities’ “living memory”, and thus likely to have at leats a marginal impact in planning horizons. While only Category 3 and above storms are shown here, it should be noted that lower category storms can sometimes have devastating consequences. Tropical storm Allison (2001), not even a hurricane, was the Houston area’s costliest storm ever.
