Just after 9 p.m., the Weather Service issued a flood advisory for the entire Clark County, home of Las Vegas, warning that flooding could affect low-lying areas with poor drainage. Wind gusts  up to 64 mph were recorded near the North Las Vegas Airport and  the Las Vegas Strip, and the weather service received "multiple reports" of trees being burned by lightning strikes. 

 The area will be under  flood watch from 11 a.m. Friday to midnight Saturday, according to the Bureau of Meteorology, with a potential  slow-moving thunderstorm that could lead to heavy rain and flash flooding by Monday. and an evening storm probability of at least 20%. 

 The storm brought 0.58 inches of rain to Las Vegas. This is almost double the average rainfall for the entire month of August, or 0.32 inches. 

 Total precipitation in the city also increased to 1.28 inches during this monsoon season, which began on June 15,  according to the National Weather Service. This is his best in 10 years. Total precipitation is likely to continue to increase until he September 30, when the season ends.

Both recent floods were caused by the southwest monsoon. The southwest monsoon occurs when the prevailing winds switch from  west to  south, pushing humidity northward. This year's southwest monsoon was particularly intense and helped ease the drought conditions in the region, but it also caused many significant floods. Last week, 1,000 people were stranded in California's Death Valley National Park due to heavy rains that occur every 1,000 years. 

 Scientists say human-induced global warming  is increasing extreme precipitation events. Hotter air accelerates evaporation, making more water  in the atmosphere available for heavy rainfall. The Intergovernmental Panel on Climate Change has found some evidence that southwest monsoon precipitation has increased since the 1970s.
