Remnants of Tropical Storm Rachel break a Las Vegas daily rainfall record as the valley nears an all-time October mark

What happened

The remnants of Tropical Storm Rachel brought heavy rain to the Las Vegas Valley on Sunday, the Las Vegas Review-Journal reported. Between midnight and the morning hours, Las Vegas recorded 1.08 inches of rain, according to a post on X from the National Weather Service's Las Vegas office.

That total broke the record for the date and tied the all-time daily rainfall record for the month of October, the weather service said. With more rain in the forecast, the Review-Journal reported that the valley was close to setting an all-time rainfall record for the month of October.

How Sunday's rain compares

A record tied from 1947

The previous record for the date was 0.78 inches, set in 2012, according to the weather service. Sunday's 1.08 inches also tied the all-time daily record for October, which was set on Oct. 12, 1947.

Still catching up for the year

Before Sunday, the city was well behind its usual rainfall. After 0.11 inches fell Saturday night, Las Vegas had 1.10 inches for the calendar year, which is 2.10 inches below the normal value of 3.20 inches, according to weather service data cited by the Review-Journal. The newspaper reported that Sunday's official end-of-day total would narrow that gap considerably.

Flood and wind alerts across Southern Nevada

Flood watch through Sunday night

The weather service placed portions of Southern Nevada under a flood watch until Sunday night, including the Spring Mountains, Red Rock Canyon and the Las Vegas Valley. The agency said excessive runoff could flood rivers, creeks, streams and low-lying areas, along with urban areas and places with poor drainage. Low-water crossings may also flood.

Flash flood warnings were issued for several parts of Southern Nevada early Sunday morning, the Review-Journal reported. The west Las Vegas Valley was under a warning until 8:30 a.m. For more coverage of emergencies and safety alerts, see our public safety section.

Wind advisory until Monday morning

A wind advisory for the Las Vegas Valley runs until 5 a.m. Monday, the weather service said. Forecasters called for south winds of 20 to 30 mph with gusts between 45 and 55 mph. The agency warned that tree limbs could come down and power outages could result.

Renaissance festival cancels Sunday activities

The threat of severe weather led organizers of the Age of Chivalry Renaissance Festival to cancel everything planned for Sunday, according to a news release from Clark County Parks and Recreation. The annual three-day event is held at Sunset Park in Las Vegas. Our earlier brief covered the festival's Sunday cancellation.

Patrick Almeido, director of Clark County Parks and Recreation, said in a statement that the department was disappointed to cancel Sunday's festivities. He added that "operating under such dangerous wind conditions presents risks we simply cannot take," the Review-Journal reported.

What the rest of the week looks like

The weather service said rain chances would decrease after 5 p.m. Sunday, but showers are expected to continue. The forecast calls for a 50 percent chance of rain Monday and a 30 percent chance Tuesday as a cold front from the Pacific Northwest interacts with what is left of Rachel.

Temperatures are also expected to drop. Tuesday's forecast high is 71 degrees, which the Review-Journal reported is more than 10 degrees below normal. Cooler-than-normal conditions, with lows in the 50s, are expected to last through next week.

What to watch next

• Whether Sunday's official end-of-day total pushes Las Vegas to an all-time rainfall record for October, as the Review-Journal reported was possible.

• The wind advisory for the valley, in effect until 5 a.m. Monday, with gusts forecast between 45 and 55 mph.
