Severe Thunderstorm Warning or Tornado Warning
During a National Weather Service-issued Severe Thunderstorm Warning or 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 warning has expired or once it has been determined that the Iowa City and Coralville areas are no longer under direct threat of the severe weather and/or tornado.
Streets may become impassable for buses during flash flooding. CAMBUS may need to modify routes to avoid flooded roadways. 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.
