A Heat Advisory went into effect Saturday for numerous South Texas counties and continued into Sunday.

The National Weather Service said a combination of hot temperatures and humid conditions will result in dangerous heat index values Sunday afternoon. The heat index could range between 110 to 114 degrees across South Texas.

Highs for Father’s Day in Eagle Pass is expected to hit 107 while Del Rio is estimated at 104. According to the NWS, San Antonio metro area hit could hit 98 degrees.

Bexar County was not under a heat advisory, however, the heat index readings are estimated to be around 105 degrees.

The NWS reminds people that prolonged exposure combined with physical activity could cause heat exhaustion and even heat stroke. You should wear lightweight, light-colored clothing, as it reflects heat and sunlight and helps your body stay cooler.

Remember to drink plenty of liquids, preferably water, even if you do not feel thirsty and avoid alcoholic beverages.

"This is dangerous heat," said KENS 5 Meteorologist Jared Silverman. "Use caution."

There are still no real chances of rain this week, Silverman said.
