Southern California is bracing for a hot and muggy week ahead, with heat watches in place and a chance of thunderstorms across the mountains and desert regions.

Temperatures are expected to increase each day into midweek, prompting officials to extend a heat advisory until 10 a.m. Tuesday, when it will transition to an extreme heat watch for even warmer conditions through Thursday evening.

Temperatures are expected to peak on Wednesday, with many locations topping 100 degrees and some reaching 110, according to the National Weather Service.

“Monsoonal moisture moving over the area will add to the discomfort, also bringing the potential for showers and thunderstorms each day,” the Weather Service said.

Those thunderstorms are most likely to occur over the mountain and desert areas as subtropical moisture is drawn into the region by a strong ridge of high pressure.

Temperatures along the coast may even reach the 90s by midweek, with very warm temperatures continuing through the night.

“Given the extreme heat and humidity, it’s highly recommended to complete outdoor activities as early as possible,” the Weather Service said.

The high pressure is expected to slowly weaken Thursday, bringing afternoon highs to within a few degrees of normal in most areas by Friday.

Two rare corpse flowers have begun to bloom simultaneously at the Huntington Library in San Marino, the nonprofit organization announced Sunday evening.

Odorysseus, the taller of the two flowers, bloomed first. A second, smaller corpse flower named Odora appears to be following close behind.

The Huntington Library is inviting visitors to take in the flowers’ unique aroma, which is often compared to rotting flesh. 

“And so it begins,” the Huntington Library wrote on social media.

Odora is shaped a bit differently than Odorysseus because its spadix is inverted due to a developmental irregularity. This is not expected to affect the blooming of the flower.

“Plot twist!” the Huntington Library wrote on Instagram. “Odora wants to steal the spotlight. Odora’s spathe has started opening, too. Tiny but mighty, we’re in for quite the show with a double bloom.”

The Huntington is open from 10 a.m. to 5 p.m. Wednesday through Monday, and is closed on Tuesdays. Reservations are required Friday through Sunday, on holidays, and during peak seasons. “Twilight stroll” hours are available on the Huntington’s website.

The public can also watch a live stream of the bloom on the organization’s YouTube channel.

Family members have identified 15-year-old Rosemead High School student Aziel Zacapala as the boy killed in a stabbing outside an elementary school in El Monte on July 10.

A candlelight vigil was held for Zacapala at the Rosemead skate park at 6 p.m. Saturday. The original location of the vigil was moved from 9700 Fern Street in El Monte, where the stabbing happened, as homicide detectives continue to investigate the scene.

Zacapala was one of three people stabbed during a fight that broke out on Fern Street around 1 p.m., according to information released by the Los Angeles Sheriff’s Department and the El Monte Police Department. Authorities were called to a local emergency room that afternoon, where two adults and Zacapala were being treated for stab wounds.

Zacapala was pronounced dead at the hospital. The adult victims are in stable condition and expected to survive, authorities said.

A GoFundMe page created to help Zacapala’s family pay for funeral expenses described the slain teen as a “beloved nephew, friend, son and high school football player” … “whose life was tragically cut short.”

“Aziel was a good kid, full of promise and kindness, and he had big dreams of making it to the big leagues as a football player,” the GoFundMe page reads. “His absence leaves a deep void in our family and community.”

Zacapala, known as “AZ” by fellow Rosemead High School students, was playing football with friends at Rosemead Park’s Fourth of July event days before the suspected attack, his family said. Now his loved ones are asking for community support as they mourn his death.

“His mother, who is currently unemployed and raising two other young children — including a newborn — has been doing Instacart orders just to stay afloat,” the GoFundMe reads. “Now, she faces the overwhelming daily hardships of supporting her family during this devastating time.”

As of Saturday night, the GoFundMe has raised $16,000 of its $24,000 goal.

No suspects were found at the scene of the stabbing and no arrests have been made in the case, authorities said.

“Investigators are still working to determine whether more than one suspect was involved,” LASD deputies said Saturday morning. “Currently, there is no suspect description available.”

Anyone with information about the stabbings is asked to call the Los Angeles County Sheriff’s Department’s Homicide Bureau at 323-890-5500.
