Strong Wind Gusts Midweek

Late Week Elevated Fire Danger for Kern County

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.
