The National Weather Service (NWS) Flagstaff AZ issued Tornado Watch 688 on Wednesday, October 21, 2026 [1]. This watch began at 10:10 AM MST and is scheduled to remain in effect until 6:00 PM MST (7:00 PM MDT) on the same day [1]. Tornado Watch 688 covers three counties in Arizona: Coconino and Navajo in the north central part of the state, and Yavapai in west central Arizona [1]. The alert specifies numerous communities within this area, including Camp Verde, Cottonwood, Flagstaff, Holbrook, Kayenta, Prescott, Sedona, Show Low, Snowflake, Whiteriver, and Winslow [1]. A tornado watch means that conditions are favorable for tornadoes to develop in and near the watch area.

Earlier on Wednesday, October 21, 2026, Arizona experienced four distinct tornado warnings [2]. These warnings were issued for Coconino and Yavapai counties [2]. Several sources reported brief tornado warnings specifically for Coconino and Yavapai counties [3]. One such tornado warning was issued for the area surrounding Flagstaff in Coconino County, remaining active until 9:45 AM on October 21 [5].

In a separate but related development, the National Weather Service office in Flagstaff, Arizona, issued an alert earlier in the morning [4]. This alert, released at 8:18 AM MST on October 21, 2026, highlighted an "extraordinary threat to life or property" specifically within Yavapai County [4]. The combination of a tornado watch and prior warnings indicates a significant period of severe weather. Residents in the affected Arizona counties are advised to stay vigilant, monitor local weather forecasts, and be prepared to take immediate shelter if a tornado warning is issued for their specific location.
