Hurricane Hilary is now a post-tropical cyclone as the storm continues to make its way north. The winds and rainfall have died down, but the storm left plenty of flooding in its wake, including road closures and some damage to several U.S. National Parks and other public land.
Joshua Tree National Park
As of Monday morning, all of Joshua Tree National Park remains closed. The park closed earlier than other areas over the threat of flash flooding. The Southern California desert area is known for flooding when it experiences rainfall. Adding a hurricane amount of rain could easily wash out roads and sweep away any cars that could be in the way.
Rain began to fall in the area on Friday, and social media posts show that even a tiny amount of rain could leave roads impassable.
In a press release, park officials wrote: “Reconsider outdoor activities for this weekend, be prepared to turn around if you experience moving water on roadways and be alert for lightning.”
Death Valley National Park
Death Valley National Park did not close before the storm, but park rangers shut down the entire park Sunday afternoon. The decision came after an inch of rain fell early Sunday, with more rain forecasted overnight Sunday.
The desert landscape saw flash flooding, and California Highway 190 is closed.
In their press release, Death Valley officials warned: “Flash floods are rivers of mud and rocks that can easily sweep cars off roads. Emergency responders may not be able to reach people in need.”
Extreme weather is a recurring issue this year in Death Valley. The park has seen record-setting temperatures and at least one death from the heat this summer.
Zion National Park
Zion National Park remains open today, but park rangers are reminding visitors about the threat of flash floods.
The park is well known for its slot canyons that, while beautiful, can quickly become death traps when they fill with water.
While the park is open, park officials have issued a warning to avoid areas like the Narrows until the storm system has fully passed.
Mojave National Preserve
Sitting between Joshua Tree and Death Valley is Mojave National Preserve, a vast desert landscape that, at first glance, can appear like an empty desert. The area closed on Friday before the storms to keep motorists and park staff safe from anticipated flooding.
“Travel in the preserve and the surrounding region is definitely not advised during these tropical storm landfall events,” Acting Superintendent Debra Hughson said in a press release. “Debris-laden water can rise rapidly on area roads and can quickly become lethal.”
As of Monday, the area remains closed as officials assess possible damage.
