[Update 12 pm] A hot and breezy day is expected across deep south Texas and the Rio Grande Valley with highs ranging from the mid 90s to a few degrees beyond 100. Small craft should exercise caution on coastal, nearshore and offshore waters of the lower Texas coast with choppy conditions expected eventually on the bay and Gulf seas of 3-6 and occasionally 7 feet. A Small Craft Advisory is in effect for the Laguna Madre north of Port Mansfield until 9pm.
[Update 12 pm] A moderate risk for life threatening rip currents are possible today along area beaches. Remember to swim near a lifeguard and with a non-inflatable flotation device, such as a life jacket or boogie board. Expect hot and breezy conditions with afternoon highs near the low 90s and heat indices up to 107 degrees. Be safe and have fun!
