Hot conditions continue, with highs expected to be near or above 100 through the week. Expect near-critical to critical fire weather conditions at times.
A Heat Advisory remains in for the western South Dakota Plains and northeastern Wyoming. This will be valid through Thursday at 9PM MDT (10PM CDT). Heat indices between 95 and 105 degrees will be possible. Drink plenty of water and take regular breaks during outdoor activities!
Red Flag Warning is in effect until 9 PM today. The Red Flag Warning has been issued due to gusty winds and low relative humidity. Any fires that develop will spread rapidly. Outdoor burning is not recommended.
Heat is one of the most deadly weather hazards, don't underestimate it! And with temperatures expected to top out over 100°F, now is the time to prepare. Heat can escalate quickly and become dangerous. So drink plenty of water through the day, even if you don't feel thirsty. Wear loose-fitting, light-colored clothing. Spend time in air conditioning and in the shade. And never leave people or pets alone in a car! 38 kids die each year by being left in an unattended vehicle. 88% are ages of 3 and under. 54% were forgotten by a caregiver. 100% of these deaths can be avoided! Animals can die of heatstroke within 15 minutes. Cracking the windows does not help, the inside still gets dangerously hot. During hot weather, keep your pets at home. If you see a pet in an unattended vehicle, do not leave until the problem has been resolved. ( Statistics courtesy of www.noheatstroke.org )
