At 7:53 p.m. on Monday, the NWS Las Vegas NV released an updated lake wind advisory in effect until 8 p.m. for San Bernardino County-Upper Colorado River Valley.

"For the Extreme Heat Warning, dangerously hot conditions with temperatures between 100 and 108 degrees expected," explains the NWS. "Extreme early-season heat coupled with high tourism rates will make this heat very dangerous, particularly for those not acclimated to the heat and/or traveling from cooler climates. Numerous daily and monthly heat records are in jeopardy through at least Sunday."

"Heat-related illnesses increase significantly during extreme heat events," states the NWS. "Winds this strong can make driving difficult, especially for high-profile vehicles. Use extra caution. Drink plenty of fluids, stay in an air-conditioned room, stay out of the sun, and check up on relatives and neighbors. Do not leave young children and pets in unattended vehicles. Car interiors will reach lethal temperatures in a matter of minutes. Take extra precautions when outside. Wear lightweight and loose-fitting clothing. Try to limit strenuous activities to early morning or evening. Take action when you see symptoms of heat exhaustion and heat stroke. To reduce risk during outdoor work, the Occupational Safety and Health Administration recommends scheduling frequent rest breaks in shaded or air-conditioned environments. Anyone overcome by heat should be moved to a cool and shaded location. Heat stroke is an emergency! Call 9 1 1. Monitor the latest forecasts and warnings for updates."

This advisory is in effect until 8 p.m.
