The park was hit on Wednesday night by high winds, hail and rain – up to three inches in places, a significant amount for the desert. As of Thursday morning, main roads into the park and the main visitor center were open, but all backcountry roads and dirt roads were closed and impassable. Some paved roads were also closed due to high water and flash flood debris. Road crews were working yesterday to open roads wherever possible, and rangers were checking on backcountry campers. More rain was in the forecast.
