CAMBUS Severe Weather Policy

CAMBUS Severe Weather Policy

CAMBUS will maintain service during severe weather within reasonable and safe practices. During extreme weather events, CAMBUS may need to unexpectedly modify or suspend all service. CAMBUS will communicate service modifications and disruptions on our website and social media accounts (@UIcambus on Facebook and Twitter). CAMBUS will announce service restoration following severe weather events on Facebook and Twitter. 

Riders are encouraged to subscribe to alerts from the National Weather Service and Hawk Alerts. 

Severe Thunderstorm Warning: During a National Weather Service-issued Severe Thunderstorm Warning, CAMBUS will maintain service unless conditions become hazardous to the safe operation of service. Conditions that may require service to be suspended may include excessive wind speeds or large hail.

Tornado Warning: During a National Weather Service-issued Tornado Warning for Johnson County, CAMBUS will suspend service immediately. Riders should not remain on buses or wait at CAMBUS stops; riders should seek shelter in a nearby building immediately. CAMBUS will resume service after the tornado warning has expired or once it has been determined that the Iowa City and Coralville areas are no longer under direct threat of a tornado.

Flash Flooding: Streets may become impassable for buses during flash flooding. CAMBUS may need to modify routes to avoid flooded roadways. These modifications will be announced on the CAMBUS social media sites. Areas that are susceptible to flash flooding include: Newton Road near the VA Hospital, Iowa Avenue between Riverside and Madison and North Riverside Drive near River Street.

Ice and Snow Events: CAMBUS will continue to run during ice and snow events, however significant delays are to be expected. If ice and/or snow events are so severe that University classes and other operations are closed, CAMBUS may reduce or suspend service.

CAMBUS will make every effort to maintain current and accurate information on our website, Facebook and Twitter. For questions, comments or concerns, please call CAMBUS at (319) 335-8633 or email
