Tropical Storm Rachel is poised to deliver a rare and potentially disruptive blow to Southern California this weekend, triggering a historic tropical storm watch for San Diego and forcing the city of Newport Beach to declare a local emergency after ocean water flooded streets on the Balboa Peninsula. For anyone with travel plans along the Southern California coast, the storm is a serious disruptor: heavy rain, damaging surf, gusty winds, coastal flooding and even mountain snow are all in the forecast as the system takes an unusual turn toward land.
Rachel, which spent the past two weeks churning over the open Eastern Pacific, is now forecast to approach the northern Baja California coast and push tropical moisture into the U.S. Southwest. Peak impacts for San Diego and Los Angeles are expected on Sunday, but coastal communities are already feeling the effects days in advance.
A Rare Storm Makes an Unusual U-Turn Toward the West Coast
Rachel formed in late September south of Acapulco, Mexico, and rapidly intensified into a powerful Category 3 hurricane in early October before weakening back to tropical storm strength over cooler waters. What makes the system remarkable is its path: a shift in steering winds is now whipping the storm sharply northeast toward northern Baja California and Southern California instead of sending it harmlessly out to sea.
That rare recurve has put forecasters on high alert. A tropical storm watch has been issued for San Diego County for only the second time in its history, the first coming in August 2023 during Hurricane Hilary. If Rachel makes landfall as a tropical storm, it would be the first time a tropical system has done so in Southern California since September 25, 1939, when a storm came ashore near Long Beach and San Pedro, dumping 5.62 inches of rain on Los Angeles over three days and producing wind gusts up to 65 mph.
Newport Beach Declares Local Emergency as Streets Flood
The storm is already making its presence felt. On Friday, the city of Newport Beach declared a local emergency after overnight coastal flooding sent ocean water surging onto streets and properties on the Balboa Peninsula. Driven by high tides, strong onshore winds and swells from the approaching storm, the rising water prompted city officials to close roads and urge residents to stay off the streets.
Coastal communities from Newport Beach to Long Beach were hit by significant flooding from large waves on Friday, and forecasters warn the worst may still be ahead. San Diego and Los Angeles could see record high tides on Sunday, with widespread coastal flooding possible. Along beaches stretching from Long Beach to Ventura, the storm is already causing erosion, dangerous rip currents and damaging surf.
Timeline: From Open Ocean to a Historic Watch
- Late September: Rachel forms south of Acapulco, Mexico, and begins strengthening.
- October 2: Rachel peaks as a Category 3 hurricane over the open Eastern Pacific.
- Mid-week: The storm weakens to tropical storm strength but begins a sharp recurve toward the coast.
- Friday, October 9: Newport Beach declares a local emergency as overnight coastal flooding swamps the Balboa Peninsula.
- Saturday: Rain and gusty winds begin to spread into Southern California.
- Sunday, October 12: Peak impacts arrive, with the heaviest rain, strongest winds and highest tides expected.
What Travelers Need to Know Before Heading to SoCal
If your weekend plans include the Southern California coast, here is what forecasters and officials are telling travelers and residents.
Expect flooding and road closures. Widespread rainfall totals of 1 to 3 inches are expected, with locally higher amounts possible. That could trigger flash flooding of normally dry washes and roadways, especially in mountainous and canyon areas. Officials warn that roads may be impacted by flooding and mudslides, so check conditions before traveling.
Stay off beaches and out of the water. Dangerous rip currents, large breaking waves and significant erosion are forecast along the coast. Beach and shoreline closures are possible, and high surf has already forced some closures in Orange County. High tides on Sunday could push water onto low-lying roads and beachfront properties.
Plan for wind and possible flight delays. Gusty winds above 40 mph are possible across the region. Allegiant Air says it is actively monitoring Tropical Storm Rachel and may adjust its flight schedule; other carriers are likely doing the same, so check your flight status before heading to the airport.
Watch for snow in the mountains. In a rare twist, moisture from Rachel combined with colder air could produce snow at higher elevations, including parts of the Sierra Nevada and Southern California mountains. Mountain travelers should be ready for slick roads and winter driving conditions.
A Busy Pacific: Rachel Isn't the Only Storm to Watch
Travelers heading to Mexico's Pacific resorts should also keep an eye on Hurricane Simon, a separate storm forecast to strengthen into a major hurricane as it approaches the west-central coast of Mexico near Puerto Vallarta and the Jalisco and Nayarit coastline. Delta Air Lines has already issued a travel waiver for Puerto Vallarta (PVR) for travel dates around October 10, and the storm is expected to bring heavy rainfall across southwestern Mexico. The one-two punch of Rachel and Simon makes this a particularly busy and disruptive stretch for Pacific coastal travel.
The rain forecast for Southern California varies by location. Through Sunday evening, Los Angeles and Ventura counties are generally expected to see 0.10 to 0.50 inches of rain, while other areas could see 1 to 3 inches with locally higher amounts. Even lighter totals are significant for a region unaccustomed to tropical downpours, and officials are urging caution rather than complacency. As one official told the Los Angeles Times of the approaching storm, "This is not even the worst."
The Bottom Line for SoCal Travelers
- Tropical Storm Rachel is a rare event: it has triggered only the second tropical storm watch in San Diego County history.
- Peak impacts are expected Sunday, October 12, with rain and wind ramping up Saturday afternoon.
- Newport Beach has already declared a local emergency due to coastal flooding on the Balboa Peninsula.
- Travelers should prepare for flooding, road closures, dangerous surf, beach closures, possible flight delays and mountain snow.
- Check road conditions, flight status and local advisories before traveling to the Southern California coast this weekend.
