Heat advisory issued for Wednesday

Headline Goes Here

HOUSTON - A heat advisory was issued for the Houston area Wednesday as triple-digit temperatures are expected for another day.

The National Weather Service said the heat advisory is in effect from noon until 8 p.m. An Ozone Watch was also issued. A heat advisory is issued when heat indices are at or above 108 degrees.

Houston's high is forecast for 101 degrees on Wednesday. Houston's record high for June 27 was 102 degrees, set in 1980.

Numerous records were broken on Wednesday. The high temperature at Bush Intercontinental Airport reached 105 degrees. The previous record was 104 set in 2009. Hobby Airport broke a record with a high of 102. The previous record was 99 degrees in 2009. Galveston broke its record high with 97 degrees. The previous record was set back in 1875. College Station had a record high of 106. Wharton set a record of 104 and Angleton set a record at 102. Sugar Land tied it's highest temperature with 102 degrees.

Residents are urged to take extra precautions if they work or spend time outside. Reschedule strenuous activities to early morning or evening, and wear lightweight or loose-fitting clothing. Also, drink plenty of water.

Demand for electricity also goes up as the temperatures rise. The Electric Reliability Council of Texas said it thinks there's enough power to go around, but there's no promise that it will be like that all summer.

Electric provider NRG recently brought 1,100 megawatts of power online.

"It's enough power that on the hottest day of the year, when people are running air conditioners, we can supply the needs of about 200,000 households," NRG spokesman David Knox said.

When there's a heat emergency, power companies are not allowed to turn off service because of lack of payment.

Some parents took their children outside for fun on Tuesday, but they made sure everyone had plenty of water and lots of breaks in the shade.

KPRC Local 2 tested the temperatures on some playground equipment near Memorial Park. Metal playground equipment tested at 127 degrees. The hottest reading was on a slide that was 155 degrees.
