* Lowest recorded temperature = -90° F. 20% probability temperature lower than -60° F during worst month /
location.
** Highest recorded rain rate = 436 mm / h. 0.5% probability greater than 120 mm / h during worst month / location.
*** Highest recorded steady wind = 342 km / h. 1% probability greater than 100 km / h during worst month / location.
**** Highest recorded gust = 378 km / h. 1% probability greater than 150 km / h during worst month of worst location.
