We have extended the Lake Wind Advisory for the San Luis Reservoir and along Highway 152 through 11 PM Thursday (Jul 9). We have also issued a Lake Wind Advisory for Lake Isabella and the Kern River Valley from 5 PM this afternoon until 11 PM Thursday. Sustained winds of 15 to 20 mph and gusts up to 35 mph are expected at San Luis Reservoir. Sustained winds of 15 to 25 mph and gusts up to 40 mph are expected at Lake Isabella. Gusts this high are capable of producing whitecap waves dangerous to small watercraft and are dangerous to drivers, particularly those in high-profile vehicles. Exercise caution if recreating at San Luis Reservoir and Lake Isabella or driving in the area.
The Fourth of July falls during the driest part of the year. Grasses and brush are fully cured, and low humidity dries them out even further. Under these conditions, a single spark can grow into a fast-moving fire within minutes. Wind is the multiplier. Gusts push flames into fresh fuel and carry embers ahead of the fire, starting new spot fires downwind. 🎆 Fireworks rules vary by city, county, and agency, and many areas ban them entirely. Check with your local fire department or county authorities. 🔗 weather.gov/hanford
CPC 6-10 day temperature outlook has the Central Valley mostly in the 60-70% probability for above average temperatures from July 12th-16th. The 16th looks to be the hottest day on this outlook. Remember to stay cool, avoid the outdoors during the hottest parts of the day, and help the more vulnerable population (infants, 65+ years of age, unhoused) to stay cool.
