Central California Fire Risk

A Fire Weather Watch is in effect for the San Joaquin Valley from Merced to Kern County and the adjacent Coastal and Sierra Foothills. The Fire Weather Watch is in effect from mid-morning to late evening on Thursday, May 22nd. At that time, warm temperatures, dry air and strong winds will make the dry grass suspectable to fire starts.

With the passage of a weak disturbance over Northern California on Thursday May 22nd, strong winds will be generated across Central California. A Wind Advisory has been issued for the Mojave Desert Slopes due to West winds 20 to 30 mph and gusts to 55 mph expected. Areas affected include Walker Pass, Indian Wells Canyon, and CA highways 14, 58, and 178 and US highway 395.

While air temperatures will be in the upper 80s and low 90s through the weekend, keep in mind that water temperatures can be much colder than air temperatures due to the water originating from snowmelt runoff. Rivers are also running swift due to gradual increases in flow rates from dam releases. It takes less than 15 minutes to lose your dexterity in water below 60 degrees! Always wear a life vest, always bring a life preserver with you, and do not go into closed rivers, streams, and lakes.

Relative humidity values less than 20% are expected on Thursday, May 22nd. When combined with drying fuels and stronger winds, a risk for conditions favorable for grass fire development will exist. Reduce fire risk by careful use of lawn mowers to cut dry grass and avoid dragging parts or chains from your vehicle. This image provides information on what can cause wildfires to start.
