The combination of hot temperatures and humid will result in oppressive heat conditions across the Rio Grande Valley and Deep South Texas this week with heat indices or "feels like" temperatures in excess of 105 degrees each afternoon. Heat-related illnesses may occur for anyone working or playing outdoors for extended periods of time. Be sure to drink plenty of water, take frequent breaks in the shade or air conditioned structures, wear loose fitting and light colored clothing, and NEVER leave pets or kids unattended in vehicles outside for any length of time.

A moderate risk of rip currents is expected again today due to increased wave action from the breezy southeasterly winds. An isolated shower or thunderstorm will be possible under partly cloudy skies. Remember to swim near a lifeguard and apply the sunscreen often.

Hot and humid conditions will intensify through the workweek. Heat indices or "feels like" temperatures will peak from 107 to 113 degrees Tuesday and 109 to 119 midweek, into the latter half of the week. Practice heat safety by staying hydrated, limiting outdoor activity, prepping the kids/pets and dressing in light weight/colored clothing. Mostly sunny to partly cloudy skies should generally continue throughout the week. Otherwise, expect a breezy to windy end to the week, into the weekend.
