As the temperatures continue to peak in the triple-digits, the National Weather Service is posting a heat advisory for all of Central Texas.
The advisory is in effect until 7 p.m. Saturday night.
With temperatures ranging between 100 and 105 degrees, the heat indices could rise to nearly 110 degrees.
You're urged to stay in an air conditioned area, out of the sun and check up on relatives and neighbors, especially the young and elderly.
Wednesday's temperature hit 105 degrees making it the hottest June 24th in Austin weather history and area residents broke another record just trying to keep cool.
June 24 marked an all-time peak demand of energy.

Between 4 and 5 p.m., 2,518 megawatts of power surged through Austin power lines, according to Leslie Schneiweiss with Austin Energy.
Ironically, the previous record of 2,514 megawatts was set just last year during the typical peak of summer, but in August. Wednesday's record fell on only the third full day of summer 2009.
"On a normal summer day when temperatures are in the 90s, peak demand is usually somewhere between 2,200 and 2,400 megawatts. In the spring it's more like 1,900 megawatts," Schneiweiss said.
Austin Energy's original peak projection for this year of 2,542 megawatts had actually been lowered to 2,477 megawatts based on the downturn in the economy.
Experts advise residents not to worry, as more power is available if it's needed.
"We have 2,700 megawatts of firm power generation, so we have plenty of power to keep Central Texans cool on these hot summer days," Schneiweiss said.
Texas' energy grid, maintained and controlled by ERCOT, holds a 17 percent reserve beyond their peak.
However, more record hot days in the triple digits ahead means a greater chance for another record of peak usage. There are some steps you can take to help lighten the power load.
The city recommends you leave lights off and avoid running power-hungry appliances like dishwashers and dryers during the hottest hours of 3-6 p.m.
