You cancel the flight since the expected dangerous weather conditions along the route would demand too much of the passengers. Because of the expected turbulence you select a flight level below FL 250. Owing to these reports and taking into account the presence of heavy thunderstorms at planned FL 310 you select a higher flight level (FL 370). You show no further interest in these reports, since they do not concern the route to be flown.
