(CNN) Dorian has left the United States but is still causing trouble

The post-tropical cyclone made landfall near Sambro Creek in Nova Scotia, Canada, at 7:15 p.m. Atlantic Standard Time on Saturday.

The storm's estimated maximum sustained winds were 100 mph (155 km/h) when it made landfall 15 miles (25 km) south of Halifax, according to the National Hurricane Center. Dorian is moving northeast at 30 mph.

The storm is still dangerous with maximum sustained winds equivalent to a Category 2 hurricane. Hurricane warnings remain in effect for parts of Nova Scotia and Newfoundland, the center said.

The hurricane center transitioned the storm from a hurricane to a post-tropical cyclone earlier on Saturday. The loss of its hurricane status refers to the fact that it no longer has a warm core, CNN meteorologist Gene Norman explained, but Dorian is still a low-pressure system.
