Early Season Heatwave Threatens Western US

In-Depth Analysis

The heatwave is driven by a strong and persistent high-pressure system, often referred to as a "heat dome," settling over the western US. This system is expected to bring two waves of intense heat, first impacting the West Coast and then spreading eastward.

In Southern California, daily temperature records are at risk of being broken, with potential for all-time March records to fall. The interior Southwest, including deserts in California, Nevada, and Arizona, could see temperatures exceeding 100°F (37.8°C).

The rapid snowmelt caused by the heatwave is a concern for water managers, as it could lead to an early peak in runoff and potentially lower river and reservoir levels later in the spring and summer.

While the increased fire risk is somewhat mitigated by light winds in California, the risk is higher further east due to ongoing drought conditions and stronger winds.
