Flood Watch
Issued: 8:09 AM Sep. 29, 2026 – National Weather Service
...FLOOD WATCH REMAINS IN EFFECT THROUGH THIS EVENING... * WHAT...Flooding caused by excessive and long duration rainfall. * WHERE...All of northern and central Arizona. * WHEN...Through this evening. * IMPACTS...Flooding will be possible over burn areas, low-water crossings, creeks, streams, washes and swimming holes. Larger creeks and rivers may exceed bankfull. Flooding of paved roads and highway underpasses will be possible. Unpaved roads could become muddy and impassable. * ADDITIONAL DETAILS... - Low pressure will interact with tropical moisture from the eastern Pacific. This could potentially produce numerous showers and embedded thunderstorms, with heavy rain that will fall over saturated soils and burn scars. This could lead to localized flash flooding and rises on local rivers, such as the Little Colorado River. - Additional information is available at weather.gov/flagstaff. PRECAUTIONARY/PREPAREDNESS ACTIONS... You should monitor later forecasts and be alert for possible Flood Warnings. Those living in areas prone to flooding should be prepared to take action should flooding develop. &&
