Las Vegas residents should prepare for sweltering conditions this Labor Day as temperatures soar to 105°F, with heat lingering into the evening. Drivers on I-15 and local roads are urged to stay hydrated and use extra caution during peak heat hours.
According to the National Weather Service, winds will remain light and variable, but the heat index could make outdoor activity dangerous. By Tuesday, a 30% chance of afternoon showers and thunderstorms may provide some relief but could bring localized flooding to low-lying areas. Travelers heading home after the holiday should watch for slick roads and reduced visibility.
The extended heat combined with sudden storm chances raises safety concerns across Clark County. Residents are advised to limit time outside during the hottest hours, keep extra water on hand, and check on vulnerable neighbors. Air conditioning systems should be tested early to avoid failures during the week’s peak demand.
Even as storms approach, temperatures remain well above seasonal averages. Tuesday will reach near 100°F before showers move in. Wednesday brings a slight chance of thunderstorms, with highs near 101°F. The remainder of the week will continue hot, with highs hovering between 94°F and 100°F.
More advisories could follow if storm activity strengthens. Stay tuned to local updates for changing conditions through midweek.
