High pressure dominated the weather over Northern California which brought above normal temperatures to the region on July 24th and beyond. Rivers during this time were still fast and cold moving in the foothills and mountains with water temperatures spanning 48 to 60 degrees Fahrenheit.
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.

NWS Sacramento, CA wrote its last area forecast discussion before the first event at Jul 24, 2:13 PM PST, 2 hours 47 minutes earlier.
Area Forecast Discussion National Weather Service Sacramento CA 313 PM PDT Wed Jul 24 2019 .SYNOPSIS... Hot temperatures this week with widespread triple digit temperatures at the lower elevations. Excessive Heat Watch in effect for this weekend. Temperatures cooling to near normal next week. A few afternoon thunderstorms over the Sierra south of Lake Tahoe today & tomorrow. && .DISCUSSION... Hot temperatures are in store through the rest of the week and weekend for interior NorCal as high pressure continues to build in the West. Temperatures this afternoon are a few degrees warmer than yesterday, and will peak in the upper 90s to low 100s across the Valley and foothills. The Delta Breeze is expected to continue each evening through Friday, which will keep overnight temperatures pleasant in Delta influenced areas. The monsoon high is currently centered over the Four Corners region through the end of the week. Weak impulses over our forecast area will allow enough monsoon moisture to move northwest around the high and create a chance of Sierra thunderstorms today and tomorrow. Isolated thunderstorms are beginning to pop up over eastern Tuolumne county and Alpine county this afternoon. Have introduced precipitation chances further north along the Sierra crest up to Highway 50 for Thursday as HREF is suggesting the possibility of storms that far north. For now have not introduced precipitation chances on Friday as ensemble models keep chances out of our forecast area. However, will need to keep an eye on elevated stability chances. For the weekend, ensemble guidance is in good agreement that an area of high pressure will be centered over southern California with ridging extending into the interior of NorCal. This will allow temperatures to increase significantly Saturday and Sunday. Saturday temperatures are expected to be around 4 to 8 degrees hotter than Friday. Temperatures will be around 8 to 12 degrees above normal Saturday and Sunday with Valley and foothill temperatures around 100 to 110 degrees and the mountains around 75 to 95 degrees. Onshore flow will be cut off with this pattern, so overnight lows on Saturday will only cool to around 67 to 77 degrees in the Valley and foothills. An Excessive Heat Watch has been issued for Saturday and Sunday as these temperatures can be hazardous, especially for those groups most sensitive to heat such as children, the elderly, people spending extended periods of time outdoors, and those with chronic ailments. HEC && .EXTENDED DISCUSSION (Sunday THROUGH Wednesday)... Hot temperatures expected on Sunday as the Excessive Heat Watch remains in effect. Valley high temperatures will range from 100- 110 degrees, roughly 10 degrees above average for most locations in late July. Weak troughing returns to the West Coast Monday which will act to push the high pressure back east and lower temperatures slightly for the beginning of next week. Temperatures will be around 5 to 10 degrees cooler on Monday than Sunday, returning to near average by Tuesday. Dry weather expected for the entire period. && .AVIATION... VFR conditions continue over the next 24 hours. Clear skies except for some cumulus buildups along the Sierra crest south of Highway 50. Winds expected to be generally around 12 kt or less. && .STO WATCHES/WARNINGS/ADVISORIES... Excessive Heat Watch from Saturday morning through Sunday evening for Central Sacramento Valley-Clear Lake/Southern Lake County-Motherlode-Northeast Foothills/Sacramento Valley-Northern Sacramento Valley-Northern San Joaquin Valley-Southern Sacramento Valley. &&

On the evening of July 24th at 1700 PST three people were swimming in the Feather River Canyon when suddenly they started to be carried away by the current. Two of the swimmers escaped; however, the third person, a 9 year old child, did not. His body was located around 2000 PST under the Tobin Bridge.
As the offices recorded each death: direct deaths were caused by the weather itself, indirect ones by something it set in motion.
