Cleveland Center Weather Service Unit (CWSU)
Our main responsibility is to provide up to the minute weather information to FAA Supervisors and the ZOB Traffic Management Unit (TMU). Some of the products issued by the CWSU are the Center Weather Advisories (CWA) and the Meteorological Impact Statement (MIS). The CWA is an aviation weather warning for thunderstorms, severe icing or turbulence, and low IFR ceilings and visibility. The MIS is a 2-12 hour forecast for weather conditions, which are expected to impact ARTCC operations.
The Cleveland Center Weather Service Unit (ZOB CWSU) is located at the Federal Aviation Administration (FAA) Air Route Traffic Control Center (ARTCC) in Oberlin, OH. Four National Weather Service meteorologists staff the office. Our hours of operation are from 6:00 A.M. to 9:30 P.M. daily.
