Wednesday, April 15, 2026 @ 10:40 AM PDT - A Wind Advisory is in effect for the Kern County desert areas, including the Mojave Desert Slopes from 8 PM PDT this evening until 11 AM PDT Friday and the desert floor in eastern Kern County from 11 AM Thursday until 11 AM PDT Friday. Northwest winds 20-30 mph with gusts 45-55 mph are expected in these areas. Take caution if driving through these areas.
A low pressure trough moving through central California midweek will result in stronger wind gusts across the Sierra crest and in the Mojave Desert Slopes. This image provides probabilities for maximum wind gusts to exceed 55 mph on Thursday, April 16th.
As a low pressure trough progresses eastward later this week, northwest flow will bring dry conditions to central California, particularly in the Mojave Desert. Minimum relative humidity is expected to fall below 10 percent in this area and will accompany wind gusts between 30 and 40 mph. Take steps to reduce potential fire ignition sources.
