The government is urging Canadians to avoid travel to Hawaii as Hurricane Lane, a Category 4 storm, approaches the region.
On its website, it urged that all “non-essential travel” to be avoided.
“Avoid non-essential travel to Hawaii County, Maui County, including the islands of Maui, Lanai, Molokai, Kahoolawe, as well as to Oahu and Kauai islands due to Hurricane Lane,” the alert read.

Several Canadian and American airlines have also issued advisories over Hurricane Lane.
The U.S. National Weather Service said on Wednesday that Hurricane Lane had weakened slightly, but still had the potential to cause catastrophic damage to the region.
When will the storm approach?
Bearing 250-kilometre-per-hour winds, Lane is threatening to dump as much as 50 cm of rain over parts of the islands, triggering major flash flooding and landslides.
The U.S. Central Pacific Hurricane Center said further weakening of the cyclone was expected as it continued on a track that could see it take aim at other islands beginning early Thursday.

“The center of Lane will track dangerously close to the islands Thursday through Saturday,” the advisory said.
“Regardless of the exact track of the center, life-threatening impacts are likely in some areas as the hurricane makes its closest approach.”
Lane was about 505 kilometres south of Kailua-Kona, Hawaii, at 5 a.m. Hawaii time, U.S. forecasters said. It was expected to begin a turn toward the northwest of the island later on Wednesday, followed by a turn to the north-northwest on Thursday.
