(Richmond, IN)--Hundreds of Richmond residents withstood another day in the heat and humidity Thursday without air conditioning or even the capability of running a fan as power remained out to hundreds of customers across the city. According to RP&L’s outage map, there were still 360 customers out in the city’s four quadrants and another 236 out in unknown areas at 6 o’clock Thursday night. All of those people have been without power since storms rolled through the area on Monday night. Power was restored Thursday afternoon in one of the more heavily affected area of South 6th. There has been no estimate of when the remaining people still in the dark will have their power restored. The storm that struck the Whitewater Valley on Monday night was officially classified Thursday by the National Weather Service as a derecho. Derechos are fast-moving storms with microbursts that create wind gusts of at least 57 miles per hour. It was followed by three straight days of temperatures in the 90’s and included a record-high temperature of 93 in Richmond on Tuesday.
