The Canadian government has upped their travel warning for the U.S. east coast, warning residents to avoid all travel to the area because of Hurricane Dorian.

Their latest update, posted online Monday, says to avoid all travel from north of Deerfield Beach in Florida to the South Santee River in South Carolina.

It also notes that Fort Lauderdale and Orlando international airports have cancelled commercial flights until further notice, and that several counties in Florida have implemented curfews.

Canadians in the path of the storm should follow the instructions of local authorities, including evacuation orders, the government said on Twitter.

While the Canadian consulate in Miami may be closed, it can still provide urgent consular assistance, the update said.

Avoiding all travel is the most severe risk level and indicates “an extreme risk.”

Hurricane Dorian was a Category 5 storm when it made landfall in the Bahamas and killed five, according to Prime Minister Hubert Minnis.

The storm, since downgraded to a Category 4, is now stationary and is about 175 km east of West Palm Beach, Fla., according to the National Hurricane Center.
