As the summer of 2024 gets closer, the southwestern United States is experiencing a severe heatwave that has brought record-breaking temperatures and heightened risks for residents. While Colorado has seen some 90 degree days recently, it’s nothing compared to the extreme conditions in places like Las Vegas, NV.
Synopsis of the Heatwave
High pressure is dominating the region through Friday, keeping temperatures as much as 10 to 15 degrees above normal. Many are under Excessive Heat Warnings and Advisories through Saturday. Record high temperatures are likely in many areas through tomorrow, with a gradual breakdown of the high-pressure system expected over the weekend as a trough approaches the West Coast. While temperatures will start to retreat slightly over the weekend, they will remain above normal into early next week.
Record-Breaking Temperatures
All climate sites in the region, including Las Vegas, Needles, Bishop, Death Valley, Kingman, and Daggett, are breaking or tying record highs. Las Vegas, for example, tied for the earliest 110-degree temperature on record. The Excessive Heat Warning remains in effect through Saturday, with a slight 1-3 degree drop in temperatures expected by Friday.
Key Notes
1. Dangerously High Temperatures: Persistent and dangerously high temperatures can lead to heat-related illnesses. Avoid outdoor activities during peak heat hours, typically between 10 a.m. and 4 p.m.
2. Heat-Related Illnesses: Symptoms of heat exhaustion and heat stroke include heavy sweating, weakness, dizziness, nausea, and an elevated body temperature. Seek medical attention immediately if these symptoms occur.
3. Hydration and Cooling: Staying hydrated is essential. Drink plenty of water, even if you do not feel thirsty. Avoid caffeinated and alcoholic beverages as they can contribute to dehydration. Find ways to stay cool, such as spending time in air-conditioned spaces, taking cool showers, or using fans.
4. Public Cooling Centers: Many cities have opened cooling centers to provide relief for those without access to air conditioning. These centers are typically located in community centers, libraries, and other public buildings.
5. Fire Danger: The extreme heat increases the risk of wildfires. Be mindful of local fire restrictions and take precautions to prevent accidental fires, such as properly disposing of cigarette butts and avoiding the use of fireworks or outdoor grills.
6. Travel Precautions: If you must travel, ensure your vehicle is well-maintained to avoid breakdowns. Carry extra water and emergency supplies in your car. Check the weather forecast and plan your trips during cooler parts of the day if possible.
