Tropical Storm Rachel’s Remnants Trigger Flood and Wind Alerts Across the Southwest
By Drooid · · How we work
Core Event
Remnants of Tropical Storm Rachel moved eastward across the western United States, producing heavy rain, flash-flood risk, strong wind gusts, and elevated surf along the Pacific coast. The National Weather Service (NWS) issued flood watches for large portions of Utah, southeast Idaho, northern and central Arizona, and a wind advisory for the same region. In Southern California, the storm’s moisture combined with an approaching low-pressure system to generate scattered showers, coastal flooding, and surf reaching up to nine feet.
Background & Context
Earlier in the weekend, Rachel’s core produced severe flooding in Nevada, where Las Vegas recorded 1.08 inches of rain—tying the city’s all-time October daily record set in 1947. Video footage showed water surging past casinos on the Strip. Forecasters warned that “disturbed weather” would linger as the storm’s remnants continued eastward.
Data & Statistics
- Rainfall: Las Vegas – 1.08 inches (record-tying). Utah forecasts call for 1–2 inches across most valleys, 2–4 inches possible in some areas, and localized totals of 6–8 inches on southwest mountain slopes. Southern California generally expects less than an inch, with Los Angeles County projected at 0.1–0.25 inch and higher amounts in the mountains. Orange County may see moderate to heavy rain, raising the risk of localized flooding.
- Wind: Utah wind advisories anticipate gusts of 55–60 mph, with potential peaks of 70 mph or more, especially where “sting jets” could develop.
- Coastal Conditions: Surf along Los Angeles and Orange counties is forecast at 3–5 feet, with occasional sets up to 9 feet. Morning high tides are expected to approach 7 feet, and a coastal flood warning remains in effect through Sunday afternoon.
Official Statements & Responses
City officials in Newport Beach declared a local emergency, activating pumps and tidal valves to protect streets from ocean water intrusion. The Long Beach building-inspection team issued preliminary red and yellow tags for structures threatened by high surf.
On-the-Ground Reports
Social-media videos captured a torrent of water racing past the Las Vegas Strip, while in Long Beach the historic boardwalk was torn apart by waves. Streets in Newport Beach flooded, prompting the emergency declaration and urging residents to avoid low-lying areas.
Conflicting Reports & Gaps
Forecast models differ on the exact track of Rachel’s remnants, leading to a range of projected rainfall totals for Utah’s mountains versus valleys. The NWS also noted that additional precipitation over the Southwest is not associated with Rachel but stems from a separate system moving across the West, adding uncertainty to total rainfall estimates.

What’s Next
The rain is expected to be short-lived, with cooler temperatures on Monday and a return to warmer conditions by the following weekend. Flood watches remain in effect through Monday afternoon, and the NWS projects that precipitation will taper off by Wednesday. Coastal flood advisories will continue until early Tuesday, while surf and wind are forecast to subside after the weekend’s peak.
