Disclaimer
NOTE: Weather is unpredictable, so floods are too. The alerts provided err on the side of caution. It is possible that you may receive a warning and the events described do not occur. This is, in part, because floods in Pima County can develop so quickly that we have to anticipate possible events early in order to give the public reasonable time to react to the potential threat. In addition, there are many unpredictable factors that affect the extent of flooding. Flood damage may be lower or higher than what we expect. The District strives to provide the best possible information based upon the best available data and is not liable for errors. No message can guarantee your safety.
We will occasionally be wrong, but that does not mean that the safety messages should be ignored. It is your responsibility to use sound judgment in and around flood waters.
Due to the fast-changing pace of flood conditions, the flood discharge at which flood alerts are sent may vary from those indicated in the individual watercourse pages based on real-time evaluation by District staff. In addition, flood alerts may be sent to a larger inundation area than the current discharge predicts in order to provide additional warning time to residents.
