Hilary, the first tropical storm to hit Southern California in more than 80 years, headed to Indian Country, affecting as many as 60 different tribal nations across California, Nevada, Arizona, and Utah. Hilary was an unprecedented and severe storm that unleashed high winds and heavy rains in Southern California Sunday evening and continued its path into parts of Nevada, Arizona, Utah, Idaho, and Oregon until Tuesday night. The California Highway Patrol posted images on social media of flooding, mudflows, and debris that washed out some roadways and people left their cars stranded in standing water.
