The skies above Southern California have unleashed their fury, prompting an urgent and potentially life-threatening Flash Flood Warning for significant portions of Los Angeles and Riverside counties. As Tropical Storm Hilary makes its unprecedented approach, bringing torrential downpours, authorities are urging residents to take immediate precautions against severe and rapid flooding.
This critical warning, issued by the National Weather Service, covers a vast stretch from Malibu and the Santa Monica Mountains across to the San Bernardino and San Gabriel Mountains, and eastward into the communities of the Coachella Valley, including Palm Springs.
It's a dire call to action for areas expected to experience the most intense rainfall from Hilary's powerful outer bands, particularly until the late evening hours.
Forecasters are not just predicting heavy rain; they're warning of life-threatening flash flooding, which can turn streets into raging rivers in mere minutes.
Compounding the danger are the potential debris flows, especially in recent burn scar areas such like the Bobcat Fire area in the San Gabriel Mountains. These flows can carry mud, rocks, and vegetation, posing an extreme threat to homes and infrastructure.
The impact zones are extensive. In Los Angeles County, residents from Malibu, the Santa Monica Mountains, the San Gabriel Mountains, and the Antelope Valley are under this immediate threat.
In Riverside County, the warning extends across the San Bernardino Mountains, the San Gorgonio Pass near Banning, and the vulnerable communities of the Coachella Valley. This is not a drill; the potential for catastrophic conditions is real.
Emergency services are clear: if you are in a warned area, move to higher ground immediately.
Do not attempt to walk or drive through floodwaters. Just six inches of fast-moving water can knock an adult off their feet, and a foot of water can sweep a vehicle away. Turn around, don't drown. These flash flood warnings signify an imminent threat to life and property.
Beyond the immediate flash flood threat, a broader Flood Watch remains in effect for much of Southern California, including inland Orange County, Santa Barbara County, and Ventura County.
This indicates that conditions are favorable for flooding, and residents in these areas should also remain vigilant and prepared for rapid changes in weather.
As Tropical Storm Hilary continues its relentless march, residents across the region must prioritize safety. Stay informed by monitoring local weather alerts and emergency broadcasts.
Have an evacuation plan ready and ensure your family knows what to do in case of rapid flooding. This is a dynamic and serious situation, demanding everyone's full attention and cooperation.
