Many people in McKinney are feeling the heat more than the rest of us.
For the second day in a row, the power has gone out at their homes during the hottest time of day.
As of Thursday evening, about 1,500 homes in and around McKinney were without electricity. Many of the homes are in a neighborhood near Highway 75 and El Dorado Parkway.
Some homeowners say the power went out at about 1 p.m. and was still out as of 10 p.m. Others already had powered restored.
The latest news from around North Texas.
Oncor crews were seen swarming this neighborhood Thursday evening trying to find the problem.
An Oncor spokesperson said later that two transformers blew and confirmed it was the result of added strain on the system.
No timetable was given for when electricity will be completely restored.
Homeowners coped with no air conditioning by keeping blinds, doors and refrigerators closed to preserve as much cool air as possible.
“It doesn't help anybody in the neighborhood when the temp is 108 or 109 degrees without electrical power. my wife Judy and I have talked about it. It's something that often we take for granted,” said homeowner Dick Thompson.
Oncor says the outage is isolated and that they're prepared to handle strain on the system in the days ahead.
Several electric companies are encouraging people to conserve electricity between 2 and 6 p.m. on Friday.
With such oppressive heat in the forecast, North Texans are reminded to check on their friends and loved ones with health problems as they may be among the most susceptible to heat exhaustion and heat stroke.
As always, never leave young children or pets unattended in an enclosed vehicle, even for a short amount of time, as temperatures can quickly rise to threatening levels.
Pets should not be left unattended outdoors for more than a few minutes.
