running around 15 degrees above seasonal normals. Moderate HeatRisk
(level 2 out of 4) will spread across the southern half of the

Palms. Major HeatRisk (level 3 out of 4) is expected in some of the
lower desert valleys, including Death Valley and cities in the lower

into the area, winds will also increase, with southwest wind gusts
of 20 to 30 mph possible over the southern Great Basin from Tuesday
afternoon through Thursday afternoon.
