Tropical Storm Hilary, which formed 470 miles off the coast of Manzanillo, Mexico, became a hurricane on Thursday, and could bring a mix of heavy rains, big surf, and flash flooding to regions of California and the Southwest that rarely see such precipitation, according to the forecasters.
“Confidence continues to increase on a significant heavy rainfall/high impact event to unfold and focus across parts of the Southwest and California beginning Saturday to at least Monday,” the National Weather Service said on Thursday. ”
