Urgent Warning: Flash Flooding Threatens Joshua Tree National Park

The National Weather Service has issued a flash flood warning for Joshua Tree National Park, effective immediately. Heavy rainfall in the surrounding mountains is causing rapid runoff, leading to a significant risk of flash flooding in low-lying areas and washes within the park. This warning is in effect until further notice.

What to Do if You're in Joshua Tree National Park

Seek Higher Ground Immediately: If you are currently in Joshua Tree National Park, seek higher ground immediately. Do not attempt to cross any flooded washes or streams. Flash floods can rise rapidly and with immense force, sweeping away vehicles and people.

Stay Informed: Monitor local news and weather reports for updates on the flash flood warning. Cellular service can be unreliable in the park, so rely on pre-downloaded weather apps if possible.

Avoid Hiking and Backcountry Activities: All hiking and backcountry activities are strongly discouraged until the flash flood warning has been lifted. Even seemingly dry washes can become raging torrents in minutes.

Understanding Flash Flood Dangers

Flash floods are characterized by their sudden and rapid onset. They can occur with little or no warning, making them particularly dangerous. The combination of steep terrain and limited vegetation in Joshua Tree National Park increases the vulnerability to flash flooding during periods of heavy rainfall.

Key Danger Signs:

• Rapidly rising water levels: A sudden increase in the water level of a wash or stream is a crucial indicator of an impending flash flood.
• Muddy or debris-filled water: This indicates that water is flowing swiftly from higher elevations.
• Changes in water color or sound: A change in the appearance or sound of a usually calm water source can signal a potential flash flood.

Precautions to Take

Before visiting Joshua Tree National Park, or any desert environment prone to flash floods, always:

• Check the weather forecast: Be aware of predicted rainfall and potential flash flood warnings before heading out.
• Inform someone of your plans: Let a friend or family member know your itinerary and expected return time.
• Carry a fully charged cell phone and a physical map: Cellular service may be unreliable, so a map is essential.
• Know your route and have an escape plan: Familiarize yourself with potential escape routes in case of a flash flood.

The safety of visitors and park personnel is paramount. Heed this warning seriously and take necessary precautions to ensure your safety. Further updates will be provided as the situation evolves.
