Flash Flood Threat Expands Across the Southwest as Rachel’s Remnants Move Inland
The remnants of Tropical Storm Rachel continue to spread inland across the Southwest, prompting flash flood concerns for parts of Southern California, Arizona, and Nevada. According to the FOX Forecast Center, a low-pressure system in the upper levels of the atmosphere has been cut off from the main jet stream, meaning it has lost the traditional west-to-east movement of normal weather patterns. This stalled system is expected to produce persistent wet weather, with rainfall amounts of 1–2 inches possible in some areas. A level 1 and 2 out of 4 flash flood threat is in effect for these regions today, as the slow-moving storm could lead to localized flooding.
The impacts on Southern California and the Southwest have already been significant. Over the weekend, months of rainfall fell in just a few hours, overwhelming drainage systems and causing dangerous conditions. Portions of Los Angeles, Ventura, and San Bernardino counties are facing a significant flash flood threat on Wednesday. While the worst of Rachel’s remnants seem to be over for Southern California, the risk remains as the system continues to drift eastward. Meanwhile, the East Coast is forecast to remain clear since Hurricane Isaias has moved well offshore, leaving the Southwest to bear the brunt of the severe weather.
In addition to the flood threat, recovery efforts from previous storms are complicating the situation. About 158,000 customers remained without power Monday morning in the Florida Panhandle and southern Alabama, according to poweroutage.us, though that is separate from Rachel’s impacts. In California, transportation officials are monitoring vulnerable roadways. State Route 27 is likely to remain closed at least through Friday due to the storm, and there is no estimated time for reopening. However, Pacific Coast Highway will remain open through the Palisades Fire recovery work zone, which stretches from Sunset Boulevard to Carbon Beach Terrace. Authorities warn that the closure of SR-27 could be extended if conditions worsen.
Residents in the affected areas are urged to stay informed and avoid traveling through flooded roads. The FOX Forecast Center notes that this cut-off low-pressure system could linger for several days, prolong
