5-Day Outlook

A Heat Advisory is in effect for Cameron, Willacy, and Kenedy counties from 11 AM until 6 PM today. Remember to stay hydrated, take advantage of air conditioning, and practice heat safety! Learn the symptoms of excessive heat exposure and the appropriate responses at weather.gov/safety/heat-illness

There is an Extreme Heat Risk across Deep South Texas and the Rio Grande Valley today. If spending time outdoors be sure to stay hydrated and practice heat safety. Visit weather.gov/heat for heat safety tips and resources.

Wildfires are caused by a spark (usually man-made) in the presence of fuel (dry vegetation) and oxygen. Strong winds, high temperatures, low humidity and drought conditions can further impact the fire’s spread. To stay Weather-Ready and protect yourself from wildfires, visit weather.gov/safety/wildfire

Favorable weather and surf conditions will make going back to work more difficult to do today.

Hot temperatures will continue through the period. Isolated sea breeze showers and thunderstorms are possible each afternoon, with the highest chances Thursday and Friday.
