(AP) -- ST. LOUIS (AP) -- Three more heat deaths have been confirmed in St. Louis, bringing the total from the summer heat wave to 17 in the city.

The deaths announced Monday included three men, ages 64, 65 and 71. All 17 deaths in the city have occurred since June 28. Temperatures are expected to climb back above 100 degrees on St. Louis on Wednesday and Thursday, raising concerns about more heat-related deaths and illnesses.

Also Monday, the city asked the U.S. Centers for Disease Control and Prevention to create a national heat death reporting system. City officials say the lack of a national reporting system prevents jurisdictions from learning from each other.
