Two people died in Las Vegas of heat-related causes.
The local office's own words before the first event, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.
NWS Las Vegas, NV wrote its last area forecast discussion before the first event at Aug 31, 9:43 PM PST, 2 hours 17 minutes earlier. Its key messages:
Area Forecast Discussion National Weather Service Las Vegas NV 1043 PM PDT Sun Aug 31 2025 .KEY MESSAGES... * Dry conditions and near to above normal temperatures through the holiday weekend. * A mid-week influx of monsoonal moisture brings precipitation chances up and temperatures down. && .DISCUSSION...through next Saturday. High pressure is currently in place over the western United States, which will maintain temperatures a few degrees above average today and tomorrow. This will result in widespread Moderate with some isolated areas of Major HeatRisk in certain valleys around the Mojave Desert, including Death Valley and the Colorado River Valley. Precipitation is not expected at most locations. Some low and mid level moisture remains below 500 mb, but dry and stable above 500 mb should limit shower development. The only location with precipitation potential today is the eastern Sierra. The presence of slightly higher moisture and a boost from orographic lift may allow for isolated shower development near Bishop this afternoon. An area of low pressure will move inland midweek, which will push the high eastward and allow monsoonal moisture to advect back into the region. Low end PoPs return to southern Mohave County as early as Monday afternoon, but anything that does develop will remain isolated and generally over the higher terrain. Moisture increases on Tuesday with improved southeasterly flow. The trajectory seems to favor eastern California on Tuesday before a shortwave pushes the moisture east on Wednesday, causing the highest POPs to shift east into southern Nevada, northwestern Arizona, and eastern San Bernardino County. From there, moisture and instability will continue to increase through the end of the week. Showers and thunderstorms are possible each afternoon. More specific forecasting of convection will likely have to be done on a day-by-day basis as preceding convection and cloud cover will greatly influence the daily evolution of precipitation chances. Regardless, flash flooding and strong outflow winds are potential hazards with these storms. Stay tuned for details with upcoming forecasts. && .AVIATION...For Harry Reid...For the 06Z Forecast Package...Winds will follow their typical daily directional patterns with speeds of 10 knots or less through tomorrow morning. Easterly winds may flirt with 10 knots at times tomorrow afternoon. Wind speed will decrease after sunset. VFR conditions will persist with FEW mid- level clouds will develop over the higher terrain tomorrow afternoon.

For the rest of southern Nevada, northwest Arizona and southeast California...For the 06Z Forecast Package...Smoke from the Garnet Fire on the west side of the Sierra is forecast to move into the Owens Valley tonight, with temporary reductions in visibility possible through the overnight period into the morning hours. Winds will follow typical daily directional patterns through tomorrow morning with sustained speeds of 12 knots or less. Breezy southerly winds will pick up across the area tomorrow, with the exception of the western Mojave Desert where breezy east-southeastely winds will pick up in the afternoon. && .SPOTTER INFORMATION STATEMENT...Spotters are encouraged to report any significant weather or impacts according to standard operating procedures. && DISCUSSION...Meltzer AVIATION...Stessman For more forecast information...see us on our webpage: https://weather.gov/lasvegas or follow us on Facebook and Twitter
