1 heat, as filed by the National Weather Service.
Deaths and injuries are direct and indirect together, as the offices filed them. Damage is property and crops in the dollars of the year, not adjusted for inflation, and only where an office estimated it.
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 Jul 14, 1:40 PM PST, 1 hour 20 minutes earlier.
MOJAVE DESERT/SOUTHERN GREAT BASIN AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE LAS VEGAS NV 240 PM PDT MON JUL 14 2003 .SYNOPSIS...THE STRONG UPPER HIGH WHICH HAS BEEN CAUSING HOT AND DRY CONDITIONS WILL GRADUALLY MOVE EAST OVER COLORADO THIS WEEK. THIS WILL ALLOW MOISTURE TO INCREASE FROM THE SOUTHEAST WITH MUCH OF THE AREA SEEING A CHANCE OF THUNDERSTORMS BY THURSDAY. TEMPERATURES WILL MODERATE CLOSER TO NORMAL LEVELS BY THE END OF THE WEEK. .DISCUSSION...UPPER HIGH WILL BECOME CENTERED OVER COLORADO BY THE END OF THE WEEK. MOISTURE WILL GRADUALLY CREEP UP FROM THE SOUTHEAST OVER THE NEXT FEW DAYS AS A RESULT WITH NORTHERN MOHAVE SEEING THE FIRST CHANCE OF THUNDERSTORMS TUESDAY. THE CHANCE OF THUNDERSTORMS WILL EXTEND ACROSS ALL OF MOHAVE COUNTY AND EASTERN LINCOLN COUNTY WEDNESDAY WITH PRETTY MUCH THE ENTIRE FORECAST AREA SEEING A SLIGHT RISK OF THUNDERSTORMS BY THURSDAY AS MOISTURE CONTINUES TO INCREASE. MODELS DO NOT REALLY INDICATE MUCH INSTABILITY BUT THINK THEY ARE NOT DOING A VERY GOOD JOB WITH THE LIFTED INDEX PROG. MOST OF THE MOISTURE WILL BE CENTERED AROUND/ABOVE 500 MB SO DO NOT EXPECT ALOT OF RAINFALL WITH ANY THUNDERSTORMS THAT DO FORM. TEMPERATURES SHOULD COOL A BIT AS THE HIGH MOVES TO THE NORTHEAST BUT BELIEVE GUIDANCE IS COOLING THINGS A BIT TOO MUCH SO WILL GO ABOVE GUIDANCE THROUGH THURSDAY. EXTENDED...MODELS INDICATE WE WILL REMAIN IN A MONSOONAL PATTERN THROUGH THE EXTENDED PERIOD...BUT THERE ARE A FEW MODEL DIFFERENCES. 12Z GFS AND EURO ARE IN FAIRLY GOOD AGREEMENT WITH LONGWAVE PATTERN THROUGH THE EXTENDED TERM. 12Z GFS CONTINUES TO SHOW AN INVERTED TROUGH ROTATING AROUND THE HIGH AND THROUGH THE CWA ON FRIDAY. THIS WOULD BRING AND UPSWING TO THUNDERSTORM ACTIVITY...ESP SINCE GFS ALSO FORECASTING PW OVER ONE INCH FOR SOUTHERN 1/3 OF CWA. OTHER MODELS NOT PICKING UP ON THIS FEATURE...BUT CONSISTENCY OF GFS NEEDS TO BE CONSIDERED. OTHER NOTEWORTHY DIFFERENCE IS THE EURO IS PULLING UP A FAIRLY DECENT PLUME OF 700MB MOISTURE ON SUNDAY...GFS NOT SO MUCH. IT LOOKS LIKE THIS IS THE REMNANTS OF CLAUDETTE AND AM LEARY TO PUT IN THE FORECAST UNTIL HER TRACK IS MORE CERTAIN. TEMPERATURES SHOULD COOL SLIGHTLY BUT STILL REMAIN JUST ABOVE NORMAL. .LAS...NONE.

A man whose truck became disabled in the desert tried to walk to safety. He was overcome by the heat and died near his home.
As the offices recorded each death: direct deaths were caused by the weather itself, indirect ones by something it set in motion.
