Tropical Storm Rachel is currently battering Southern California, triggering widespread beach closures in Newport Beach and emergency flood warnings across multiple counties... Forecasters warn that life-threatening rainfall and damaging winds will persist through Sunday, Oct. 12, as the storm moves northeast.
The 7.5-foot tides battering Long Beach and Newport Beach
Coastal communities are facing a severe onslaught as high tides are expected to reach between 7.3 and 7.5 feet along the Los Angeles County coast this weekend. According to the report,this surge has already led to red-tagged homes in Long Beach after powerful waves damaged a protecctive bulkhead and flooded residential streets. Resident Brian Gerrard described the event as a "once-in-a-lifetime storm," highlighting the lack of preparation for such extreme coastal volatility.
In Newport Beach, the situation became critical enough that city officials closed all beaches and piers on Saturday morning , Oct. 10. City crews have been working around the clock to pump seawater from flooded streets and reinforce sand berms to protect low-lying neighborhoods.. The report notes that seawater had already spilled onto roads in both Newport Beach and Laguna Beach a day prior, forcing immediate road closures.
A 40% flash flood risk for Palm Springs and Joshua Tree
While the coast faces surges, the interior is bracing for deluge. The National Weather Service has flagged a 40% chance of excessive rainfall triggering flash floods across the mountainous and desert regions of Riverside and San Bernardino counties, specifically naming Palm Springs, Joshua Tree National Park, and Twentynine Palms as high-risk areas.
Meteorologist Casey Oswant of the NWS warned that mountain areas in the Inland Empire could see 2 to 3 inches of rain, with some localized spots receiving even more. This is particularly dangerous for communities like Wrightwood and Oak Glen, where steep terrain and existing widfire burn scars increase the likelihood of debris flows. The National Hurricane Center reported that as of 8 a.m. Saturday, Tropical Storm Rachel maintained maximum sustained winds of 60 mph.
Daniel Swain's warning on record warm ocean temperatures
This weather event is not an isolated fluke but the result of a specific atmospheric convergence. Daniel Swain, a climate scientist with UC Agriculture and Natural Resources, explained that this unusual event was made possible by the coincidence of an early-arriving low-pressure trough and record-warm ocean temperatures off the California coast.
This pattern reflects a broader, more alarming trend of tropical moisture penetrating further north into the Southwest than historically common.. The combination of atmospheric pressure and warming seas creates a "perfect storm" scenario that allows systems like Rachel to maintain strength and deliver significant rainfall to regions not traditionally equipped for tropical storm surges.
The cost of flood insurance and the Oct. 13 Council session
The human cost of the storm is exacerbated by a gap in financial protection. Jim Gesner , a long-time resident of the Long Beach Peninsula, noted that many of his neiighbors have not purchased flood insurance because the premiums are prohibitively expensive, leaving them financially exposed as their properties are battered by the sea.
This crisis arrives at a pivotal political moment; the Newport Beach City Council has a study session scheduled for 4 p.m. on Tuesday, Oct. 13, to discuss severe beach erosion and sand replenishment. However, several critical questions remain: will the city's replenishment plans be enough to counter rising tides, and how will the local government support uninsured homeowners who have lost their properties? The source focuses primarily on the immediate emergency response, leaving the long-term funding and infrastructure solutions as an open debate for the upcoming council meeting.
