Another day of triple digit heat expected in the mid and upper Rio Grande Valley, as well as northern ranchlands, with mid 90s expected along the coastal portions of deep south Texas and the lower valley. Mariners can expect seas of 2-4 feet on the Gulf, with a light chop increasing to a moderate chop on the bay due to increasing southeast winds this afternoon.
A low risk for rip currents is expected today along the beaches of South Padre Island and at Boca Chica. Even though the rip current risk is low today, life threatening rip currents are still possible, especially in the vicinity of the South Padre Island Jetties. Another hot day expected with partly cloudy skies and afternoon temperatures up into the low 90s. With the UV index in the extreme range, it's recommended to use sunscreen and to re-apply often. Have a fun and safe day at the beach!

Even higher heat indices or "feels like" temperatures are expected when humidity is factored in, reaching up to 110 degrees in many areas. Overnight lows will remain warm, ranging from the upper 70s into the low 80s.
