(KRON)– An 18-year-old is dead, and several others are injured after an early morning crash on eastbound I-80, near the 7th street off ramp in San Francisco’s SoMa district, according to California Highway Patrol San Francisco (CHP SF).

The crash occurred around 1:00 a.m. between a tractor-trailer, a Recology truck semi, and a grey Chevrolet Camaro, according to CHP officials.

Police said the Camaro was traveling eastbound just west of 7th Street when it made an illegal lane change to the right, colliding with the tractor-trailer as it was approaching the off-ramp.

Both vehicles crashed into the sand barrels at the top of the 7th Street off-ramp, officials said. The tractor-trailer continued onto the offramp, where it came to a stop, blocking all lanes.

After hitting the sand barrels, the Camaro continued, launching over the off-ramp bridge railing, where it dropped 25 feet and landed in the San Francisco Police Department Impound parking lot beneath the off-ramp and hitting several vehicles in the impound yard, police said. The Camaro landed upside down on top of another car.

Police said four people were inside the Camaro. The driver, an 18-year-old man, had moderate injuries and managed to get himself out of the car, police said. The right front passenger, a 17-year-old male, suffered moderate injuries as well.

The two rear passengers, both 18-year-old men, suffered major injuries. One is being treated at a local hospital, and the other was pronounced dead at 1:50 a.m. at the scene of the crash, police said.

The other three passengers in the Camaro were wearing seatbelts, and the 18-year-old who died was not wearing a seatbelt.

CHP SF officials do not believe alcohol or drugs were a factor in this crash.

SEATTLE – After waking up to a smattering of clouds this morning, skies gradually cleared through the afternoon as sunshine increased around Western Washington. Temperatures climbed into the low 60s for many communities, making for a pleasant and quiet start to the weekend.

What’s next:

Sunday will remain mild and dry with a little more warmth expected across the region. Winds will shift to a more northerly direction, helping temperatures inch upward compared to Saturday.

The warming trend will continue Monday as highs climb into the 70s under mostly sunny skies.

By Tuesday, a developing thermal trough along the Cascades will help usher in the warmest air of the week. Sunshine is expected throughout the day with temperatures soaring into the low to mid 80s for many communities.

 Some of the traditionally warmer locations could climb even higher. The warmer, drier air will also raise fire danger across parts of the region.

This weather pattern helps Seattle experience sinking air, abundant sunshine, and significantly warmer temperatures. (FOX 13 Seattle)

Water safety on hot days

If you’re planning to cool off at area lakes, rivers, creeks, or streams, remember that water temperatures remain dangerously cold despite the warmer air. Wearing a life vest is strongly encouraged.

The heat will begin easing Wednesday as temperatures fall back into the low 70s. A cooler onshore flow pattern will continue Thursday and Friday, bringing highs back into the 60s. An isolated shower or two may develop Friday as a weak weather system approaches the Pacific Northwest.

Cooler weather returns to Seattle later in the week with highs back in the 60s and a slight shower chance Friday. (FOX 13 Seattle)
