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.
1 heat. Local standard time, as filed.
A heat wave in late June caused 10 heat deaths between June 26 and June 29 in Chicago. Tow more deaths occurred in early July even though the heat had subsided.
As the offices recorded each death: direct deaths were caused by the weather itself, indirect ones by something it set in motion.
