Hot, humid, and thunderstorms

Thunderstorms developed both to the east and west of the Coachella Valley this afternoon. A storm over Joshua Tree cleared the area by 2:00 p.m. but triggered a brush fire that has burned more than 100 acres. Read more about the fire here.

Thunderstorm activity continues through the night as storms from Arizona move westward into California deserts. Talk of thunderstorms will continue into Wednesday afternoon across the High Desert and local mountains.

The strong ridge of high pressure that has been bringing the heat to the desert southwest will remain in place through the week.

The Excessive Heat Warning remains in effect through 10:00 p.m. Thursday.

Some tropical activity to keep tabs on is Hurricane Genevieve which is currently a category 4 storm with maximum sustained winds of 130 MPH.

Moisture from this system looks to move into Southern California Friday and Saturday bringing clouds and continuing the chance for showers and storms, primarily over the mountains.
