In-Depth Analysis
The record-breaking heatwave is a result of a strong, slow-moving high-pressure system, often called a 'heat dome,' that is trapping hot air over the US Southwest. This has led to temperatures soaring 20-30°F above normal for this time of year. Several locations registered their hottest March temperatures ever, including:
- **Martinez Lake, AZ:** 110°F (43°C)
- **Phoenix, AZ:** 105°F (40°C)
- **Las Vegas, NV:** 95°F (35°C)
- **San Francisco, CA:** 85°F
The heatwave is expected to continue, with temperatures remaining high across the West and spreading eastward into the Rockies and the central and southern Plains. The weather service has warned of increased wildfire risks due to the combination of extreme heat, gusty winds, and low humidity. Human-induced climate change is exacerbating these conditions, making such heatwaves more common and more severe.
