Good morning. For a few hours on Sunday morning, the 110 Freeway was closed to cars — and open to bikers and pedestrians. See the Los Angeles Times’ photos of the event here. Onto the five USC, LA and California stories you need to know for today.

1.

An overwhelming majority of USC’s graduate student workers voted to authorize a strike Friday, calling for “fair wages” and “real recourse” from USC. A strike isn’t a sure thing: The authorization only gives union leadership the power to call one should contract negotiations fall through. The union represents teaching assistants, research assistants and assistant lecturers from nearly every academic department. “USC administration now knows that the clock is ticking,” the union wrote on Instagram. “It’s time for them to come to the table with serious proposals.”

2.

LA authorities imposed parking restrictions on streets they say need to be clear for first responders and potential evacuations as strong Santa Ana winds threaten fires across Southern California. The winds — which develop in high pressure areas in Utah and Nevada and eventually blow into California as strong, hot gusts — often fan fires and help them spread much faster than they would normally. The National Weather Service issued a red flag warning for LA and Ventura counties through at least Monday.

3.

Just 40% of California high schools offer computer science classes, putting the state at the bottom of a recent report that ranked states by percentage of schools offering computer science instruction. It’s a perhaps surprising metric for the home of Silicon Valley, but educators blamed a shortage of qualified teachers — and administrators who prioritize the subject — for the lackluster offerings. The lack of access disproportionately affects California’s low-income students, rural students and students of color.

4.

John Muir once wrote that the bighorn sheep “ranks highest among the animal mountaineers of the Sierra.” But 129 years later — as the now-endangered species’s population has dwindled to the low triple digits — half the sheep tracked by scientists died in last winter’s heavy snowfall. Some died in avalanches. Others of starvation. And even more were killed by mountain lions when they were forced to descend to lower elevations to look for food. Scientists say a lack of generational knowledge in herds and their already low numbers are to blame for the die-off, a major setback for the decades-long conservation effort.

5.

A suspect fleeing the scene of a San Francisco disturbance tossed a pipe bomb and molotov cocktail out the window of his vehicle at pursuing squad cars. The chase began in the early evening when officers responded to a report of an assault at the famous Saints Peter and Paul Church. Nobody was hurt, and California Highway Patrol eventually took the unidentified man into custody. Police warned residents to report any suspicious devices found on the streets.

You’re all caught up. Thanks for reading Morning, Trojan, and have a good day.
