Heat, St. Louis (C)

When: July 13, 12:00 PM CST to July 21, 11:00 AM CST
Where: St. Louis (C) forecast zone
Deaths: 4 direct, 0 indirect
Injuries: 437 direct, 0 indirect
Reported by: OFFICIAL NWS OBS.
Coordinates: 38.627, -90.198 (the zone’s center; the record gives no point)

A major heat wave hit the St. Louis area in mid-July. Temperatures ranged from the middle 90s to the around 100 with the Heat Index ranging from around 100 to 115. On July 17, 101 people were treated at Busch Stadium during the St. Louis Cardinals baseball game. To make matters worse, severe thunderstorms roared though the area on July 19 and 21, creating the worst power outage in St. Louis history. Up to 700,000 metered buildings lost power at some point through the 21st and for many the power was not restored for a week to 10 days. Over 400 heat related injuries were reported in the City of St. Louis with 4 deaths. Also, over 500 gastrointestinal illnesses were reported during the power outage. This believed to be due to people eating spoiled food from the lack of refrigeration.

The people who died

As the offices recorded each death: direct deaths were caused by the weather itself, indirect ones by something it set in motion.
