25th Anniversary of Iniki: How Hurricane Irma Compares
Hurricane Iniki was the most powerful storm to hit Hawai‘i in modern history—and was also the costliest.
On Sunday, Sept. 10, 2017, Hurricane Irma, one of the most powerful storms-ever in the Atlantic made landfall in Florida.
Here is how the two storms compared.
