An Atlanta airport official says there’ve been around 800 cancellations due to the threat of Irma, which weakened to a tropical storm Monday morning.

Hartsfield-Jackson Atlanta International Airport spokesman Andrew Gobeil says the airport will still be operational Monday and will monitor storm conditions.

Gobeil says the airport created an overflow parking plan to allow planes unable to land in areas such as Florida to park at the airport in Atlanta.

Also in Atlanta, the city’s transit system has suspended all bus and rail service ahead of the weather conditions caused by Irma.

Metropolitan Atlanta Rapid Transit Authority spokesman Erik Burton says both systems will be closed for Monday. He says officials will continue to coordinate with state and local officials along with emergency personnel to determine MARTA’s service schedule for Tuesday.
