Meteorologists are offering stern warnings as Hurricane Hillary turned Tropical Storm Hillary advance Southern California, including metro Los Angeles, San Diego and Palm Springs. Some areas of the desert, including Palm Springs are expected to get a year's worth of rain in 36 hours.
"Hurricane Hilary is expected to bring a year's worth of rain to The Coachella Valley in a 36-hour window," Mike Everett, former chief meteorologist at NBC Palm Springs posted in a Facebook message. "Flash flooding occurs there when we get a half-inch of rain. Current models have around 5" by Monday morning.
"In addition, even heavier rain (up to around 10") is likely on the east facing slopes of the San Bernardino mountains and places such as Idyllwild. This will create slide potential along the west side of the valley.
"Anyone near the Palm Springs Aerial Tramway, Tahquitz Canyon, Downtown Palm Springs, Rancho Mirage, Cathedral City, Palm Desert and La Quinta Cove should exercise extreme caution and have an evacuation plan in place.
"Rain begins midday Saturday. I expect road closures by Sunday morning. The heaviest rains will occur Sunday afternoon into Monday.
"By that point, it's possible that there will be major washouts that could impact local streets and bridges and I-10, especially eastbound. The Wash is likely to become very active as well. Areas around Tahquitz will be impacted and potentially dangerous - DO NOT try to drive or walk through rushing water," the meteorologist wrote.
The National Weather Service San Diego is predicting as of Saturday morning that Hillary will hit Southern California Sunday afternoon.
