Authorities in Vietnam were preparing to move more than 500,000 people from four central coastal provinces on Sunday as Typhoon Kajiki was set to make landfall.

More than 150,000 households in Thanh Hoa, Quang Tri, Hue and Danang were ordered to seek shelter inland.

Vietnamese carriers Vietnam Airlines and Vietjet canceled flights due to the anticipated weather conditions.

What else do we know about the typhoon?

According to the US Joint Typhoon Warning Center, Kajiki was traveling across the South China Sea with windspeeds of 175 kilometers per hour (109 miles per hour).

Heavy rains and flooding are expected.

The coastal city of Vinh was hit by heavy rain overnight, with most shops and restaurants closed by the morning.

The typhoon is expected to make landfall around 1:00 p.m. local time (0600 UTC) with winds of 157 kilometers per hour, according to Vietnam's National Center for Hydro-Meteorological Forecasting.

Vietnam suffered around $3.3 billion (€2.82 billion) in economic losses when Typhoon Yagi hit the country last year.

A social media post by the city urged residents not to go out unless necessary.
