Prof. Céline Lutoff from the Universite de Grenoble, France has completed her 6-month visit with the FLASH team at the National Weather Center. While in Norman, she and her family experienced two EF5 tornadoes that were very near (Moore and El Reno), as well as the deadly Oklahoma City flash flood. Céline assisted in many flash flood-related studies with the team. In particular, she helped launch the “social component” of the Flood Observations – Citizens As Scientists using Technology (FLOCAST) project (http://flash.ou.edu/flocast/). Her expertise was invaluable in developing the interview questions that will be used to understand societal perceptions, responses, and behavior of victims impacted by flash floods. Céline helped in the development of a photography guideline, which is presently being used to collect unique and informative photographs of flash flooding. Lastly, she co-supervised a study that is aimed at understanding the characteristics of deadly and injurious flash flooding events vs. those that have little impact on lives. Although she will be missed, we anticipate many more fruitful collaborations with her and her team in France in the future! Céline was hosted at the University of Oklahoma by the Cooperative Institute for Mesoscale Meteorological Studies.
