New backcountry alert system warns Grand Canyon visitors about flash floods in areas without cellular signal
"This new alert system provides a critical communication link in remote areas, giving backcountry users timely information about flash floods or other hazards they may encounter," said Ed Keable, Superintendent of Grand Canyon National Park. "At the same time, no technology replaces the need for personal preparation and situational awareness. Visitors should always research their route, understand the risks, and be ready to adapt when conditions change."
To subscribe for alerts, visitors can text GCRIVERALERTS to 928-707-7842 from the device they wish to subscribe to be added to the Grand Canyon River Alerts list that is maintained by Coconino County Emergency Management. Subscriptions must be made prior to leaving on a backcountry visit. For more information about how to subscribe, click here.
