MIL-OSI USA: New backcountry alert system warns Grand Canyon visitors about flash floods in areas without cellular signal

While the new alert system was developed specifically for Grand Canyon, the framework it uses could apply to most wilderness areas and be utilized by land management agencies, search and rescue units and those concerned with public safety to increase communication with people visiting or living in areas that are outside of cellular signal coverage. More than a million people spend the night in National Park Service-managed backcountry wilderness areas every year.

“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.”
