While it never officially broke 100 degrees in Houston, it sure did feel like it.
When the heat index gets high, it can be dangerous.
According to the National Weather Service, a Heat Advisory is issued when a period of hot temperatures is expected. The combination of hot temperatures and high humidity combine to create a situation in which heat illnesses are possible.
During a Heat Advisory, the NWS suggests that you drink plenty of fluids, stay in an air-conditioned room, stay out of the sun and check up on relatives and neighbors.
With the advisory in place Sunday, people were uged to do what they could to stay cool. We went to Hermann Park to see how some people were handling being outdoors.
There was a breeze at the park, which helped, but it was still a scorcher.
A lot of families were relaxing near the water and looking for shady spots.
Many were not aware of the heat advisory in effect, but they were still taking precautions.
"There's plenty of wind, plenty of cloud cover," father Robert Butler said. "It's pretty humid and hot, but like I said, we just knew the water was here, so we knew the kids would stay cool, and they have plenty of shade trees."
Eight-year-old Erica Butler managed to keep cool while also having fun at the park.
"Just getting wet and staying in the cool shade where it's cold," she said.
ABC13 Meteorologist David Tillman said the heat index reached 101 at Bush Intercontinental Airport on Sunday. It reached 107 in Galveston, 102 in Sugar Land, 105 in College Station and 109 in Bay City.
The heat was even blamed for fish deaths in Galveston Bay because, as temperatures rise, oxygen levels in water drops.
Tillman said the heat index would not be as high on Monday, and rain chances will be going up.
