  Sedgewickville, Bollinger County

  3 deaths, 2 injured, $50K damage

  What happened

  Flash flooding of two creeks resulted in two separate fatal incidents involving vehicles swept off roads. In the first incident, a vehicle carrying four people was swept away at the low water crossing of the Little Whitewater Creek on County Road 356. This location is several miles south of Sedgwickville. Two of the occupants lost their lives, and the other two were treated for injuries. The survivors were the 33-year-old male driver and a 2-year-old boy. Two young boys aged 5 and 8 years old were killed. The location of the flash flood fatalities was in a hilly area, where numerous low water crossings are prone to frequent inundation. A volunteer firefighter familiar with the area estimated the water depth was 3 to 4 feet where the driver of the SUV attempted to cross the creek. The injured victims were airlifted or taken by ambulance to regional hospitals with moderate to serious injuries. The victims were all members of the same family. In the second incident, a truck was swept away at the low water crossing of Upper Whitewater Creek on County Road 234. This location is a couple miles east of Sedgwickville. The 48-year-old male driver from Louisiana was killed. The vehicle...

  1 death, 16 injured, $4M damage

  What happened

  This strong tornado with peak winds near 180 MPH touched down in a rural area southwest of Marble Hill. A total of 19 residences were severely damaged, and 6 were destroyed. Approximately 10 of the residences were mobile homes and 15 were single-family homes. Another 50 outbuildings, such as barns and sheds, were destroyed or damaged. Seven people were inside a house that was demolished. One of the victims, a 12-year-old boy, was thrown about 50 yards from the house and fatally injured. Several others in the immediate area, possibly the other occupants of the house, were thrown into a nearby lake and swam to safety. Of the 16 people injured in the tornado, four were air lifted to hospitals with serious injuries. Cars were stacked atop cars. Several residents were trapped inside the debris of their homes for up to 3 hours. The large number of trees down across roads delayed the arrival of rescue teams.

  Bollinger

  12 injured

  What happened

  A heat wave spanning a three-day period caused heat stress problems for the unprepared. A cooling unit of an air conditioner in a Cape Girardeau office building failed, causing four employees to require medical attention. The four women spent a good part of the day in the room without air conditioning. The women became lethargic and overheated, and were taken to a local hospital as a precaution. Over a four-day period, Southeast Missouri hospitals treated at least a dozen people for heat related illness in their emergency rooms. About half of the cases involved elderly residents. Four people were treated for dehydration at one hospital on July 27. High temperatures were in the upper 90s to near 100 degrees for three consecutive days. High humidity sent the heat index up to near 115 degrees.
