Impacts:  Prolonged exposure to this excessive heat could lead to dehydration, heat exhaustion or even a heat stroke.

Timing and Overview:

Very hot temperatures are expected today, though the weekend, and into early next week. The temperatures will gradually warm each day, peaking on Sunday and Monday. Heat Advisories are likely for much of the region, with Excessive Heat Warning possible for some areas.

Regardless of warnings and advisories, all of South Central Texas will be very hot during this extended heat wave. Take extra precautions if you must work or spend time outside. Wear light weight and loose fitting clothing, drink plenty of water, and take frequent breaks, preferably in an air conditioned area. When possible reschedule strenuous activities during the morning or mid evening hours.

Young children and pets should never be left unattended in vehicles under any circumstances. This is especially true during hot weather when car interiors can reach lethal temperatures in a matter of minutes. Look before you lock!
