Southern Nevada is preparing for a weekend of significant weather, with heavy rain, strong winds, and cooler temperatures anticipated across the region. Moisture from Tropical Storm Rachel is streaming into the area, prompting a Flood Watch from Saturday morning through early Monday, alongside a Wind Advisory in effect from early Sunday to early Monday.

Saturday's forecast calls for cloudy skies, with a chance of light showers early in the day. The probability of rain and thunderstorms is expected to increase to 40% by late afternoon and evening. High temperatures on Saturday will reach approximately 88 degrees Fahrenheit, accompanied by south winds blowing between 15 and 30 miles per hour.

The chance of rain and storms significantly climbs to 90% by midnight on Saturday night. Sunday will experience widespread showers and thunderstorms, with southeast winds forecast to gust between 25 and 40 miles per hour. Temperatures on Sunday are expected to remain cooler, hovering near 70 degrees Fahrenheit.

Forecasters anticipate about one inch of rain between Saturday night and Sunday afternoon in areas like Las Vegas, which can lead to various hazards. Roads are expected to become slick, likely increasing the number of crashes due to wet conditions. There is also a strong possibility of street flooding in low-lying areas with poor drainage. Furthermore, washes are expected to fill rapidly during heavy downpours, potentially necessitating water rescues for unhoused individuals in those areas.

Higher elevations, specifically the Spring Mountains, are projected to receive even greater rainfall, with up to three inches anticipated from Saturday evening through Sunday afternoon. This substantial precipitation could lead to flooding as moisture flows down Kyle and Lee Canyon. Residents and visitors are advised to avoid outdoor activities such as camping and hiking from Saturday night through Sunday to ensure safety.

Looking ahead to early next week, a more significant cooldown is expected. Monday's high temperatures will remain near 70 degrees. Monday night will see temperatures drop into the 50s, with Tuesday highs only reaching the mid-60s. While a few additional showers with thunder are possible on Monday and Tuesday, their coverage will be more isolated, and rainfall amounts are expected to be much lower, around 0.10 inches.

The Flood Watch remains in effect from 11 AM Saturday through 5 AM Monday, advising vigilance for potential flooding conditions. The Wind Advisory is also active from 2 AM Sunday through 5 AM Monday, warning of strong winds that could create hazardous driving and outdoor conditions. Residents and visitors throughout Southern Nevada are encouraged to exercise caution, especially when traveling on wet roads and in areas prone to flooding, and to stay informed about changing weather conditions.
