A combination of wind and overloading caused a boat to capsize in Lake Mead, injuring three people.
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 Jun 23, 9:02 PM PST, 3 hours 28 minutes earlier.
Area Forecast Discussion National Weather Service Las Vegas NV 1002 PM PDT Sat Jun 23 2018 .SYNOPSIS...Hot and dry conditions will continue through much of the upcoming week. Winds will subside tonight, and lighter winds are expected for much of next week as well. && .UPDATE...Forecast on track this evening and no updates are needed. -Salmen && .PREVIOUS DISCUSSION...239 PM PDT. .SHORT TERM...through Tuesday night. Only one change of note to the forecast today. Very shallow low level moisture was surging northward across the far southern Colorado River Valley and into the lower elevations of Riverside County on southerly winds. Raised dew points somewhat in the river valley from about Bullhead City southward for tonight and tomorrow. Elsewhere, the Excessive Heat Warning was working out well today and will probably be allowed to expire this evening as temperatures come down a few degrees tomorrow. Red Flag Warning was marginal, but this was expected, and will let it ride as well. After briefly lowering on Sunday, temperatures will come back up a few degrees Monday and Tuesday, but at this time, it does not look hot enough to support another Excessive Heat Warning. .LONG TERM...Wednesday through Saturday A Pacific trough will continue to dig south into the area midweek onward, and bring a slight change to the weather pattern. Overall, nothing of immediate high impact concern sticks out, with dry air keeping precipitation at bay. Winds will pick up on Thursday as the trough approaches and the pressure gradient increases across the Great Basin. Temperatures will continue their slow downward trend as well, with highs each day a few degrees cooler than the last. After Thursday, confidence in the forecast quickly decreases. Long range models differ on how strong and how far south the main trough will be, with the GFS considerably stronger than the latest ECMWF. Based on the overall pattern and the time of the year, favor the weaker solution, which would bring some gusty winds and a gradual decrease in temperatures going into next weekend. The latest runs of the GFS are trending weaker with the system overall, and the significant temperature drop on the GFS guidance between Thursday and Friday has slacked and also shows a gradual temperature decrease towards normal. This matched well with what was previously forecast, and with confidence in the long range forecast fairly low, didnt make any major changes to the end of the week forecast. && .FIRE WEATHER...Red Flag Warning remains in effect for AZ zone 102 until 8 pm MST, with lighter wind forecast for Sunday. Hot and dry conditions will persist through the weekend and much of next week, with minimum humidity readings in the single digits and poor overnight recovery in most areas. && .AVIATION...For McCarran...Southerly winds will subside overnight, and could turn northeast for a period of time Sunday before southerly winds under 10 knots return in the afternoon. The high temp Sunday will be around 104. No weather or significant clouds expected. For the rest of southern Nevada, northwest Arizona and southeast California...Northerly winds will spread as far south as Las Vegas tonight and Sunday morning, with southerly winds persisting in areas farther south. The southerly winds should spread back across the entire area by Sunday afternoon, with speeds generally under 20 knots. No weather or significant clouds expected. && .SPOTTER INFORMATION STATEMENT...Spotters are encouraged to report any significant weather or impacts according to standard operating procedures. && SHORT TERM/AVIATION/FIRE WEATHER...Morgan LONG TERM...Wolf For more forecast information...see us on our webpage: http://weather.gov/lasvegas or follow us on Facebook and Twitter
