Urgent Warning: Flash Flooding Threatens Grand Canyon National Park

The National Park Service (NPS) has issued a flash flood warning for Grand Canyon National Park, urging visitors and residents to exercise extreme caution. Heavy rainfall in the upper watershed areas has led to a significant increase in water flow within the canyon's drainage systems. This situation poses a serious risk of flash flooding, particularly in low-lying areas and along washes.

What to Do

• Heed all warnings and advisories: Stay informed by monitoring official channels such as the NPS website, local news outlets, and weather reports. Do not attempt to cross flooded areas.
• Evacuate if necessary: If instructed to evacuate by park officials, do so immediately. Follow designated evacuation routes.
• Seek higher ground: If caught in a flash flood, seek higher ground immediately. Do not attempt to drive through flooded areas – even seemingly shallow water can sweep vehicles away.
• Avoid hiking in vulnerable areas: Refrain from hiking in canyons or areas prone to flash flooding during this period of heightened risk.
• Stay aware of your surroundings: Be alert to signs of approaching flash floods, such as rapidly rising water levels, increased stream flow, and changes in weather conditions.

Understanding the Risk

Flash floods in the Grand Canyon are a potentially life-threatening hazard. The canyon's unique geography, with steep-walled canyons and ephemeral streams, can quickly concentrate rainfall, leading to sudden and powerful surges of water. These floods are often unpredictable and can occur with little warning. Even relatively small amounts of rainfall in the upper reaches can trigger devastating flash floods downstream.

Current Situation

The NPS is actively monitoring the situation and deploying resources to ensure visitor safety. Park rangers are patrolling vulnerable areas and providing updates to the public. The specific duration of the flash flood warning will depend on weather conditions and the receding of floodwaters.

Staying Safe

Your safety is paramount. By staying informed, following official guidelines, and exercising caution, you can significantly reduce your risk during this flash flood warning. Remember, when in doubt, err on the side of caution.
