There have been five vegetation fires along the road in Oakland since June 1, at least one caused by illegal fireworks, Oakland fire spokesman Michael Hunt said.
High fire danger and several recent fireworks-related fires are to blame.
The fire near Howard Elementary School and Interstate Highway 580 was reported shortly after 3 a.m. and was quickly elevated to three alarms, with 56 firefighters responding.
The fire is burning at 3rd and Chestnut Streets in Oakland's Jack London Square.
The fire broke out shortly before 4 p.m.
There were no immediate reports of injuries or arrests.
Oakland police responding about 2:30 a.m. to the crash at Seventh Street and Frontage Road at Interstate Highway 880 found a silver 2004 Honda Civic that had struck a concrete wall.
Oakland Police and the California Highway Patrol are investigating.
A KTVU tower cam recorded smoke coming from the property, located near Foothill Boulebvard and 34th Avenue, in the city's Peralta Hacienda neighborhood.
The bus was found parked under an overpass near Wood Street and Grand Avenue on Wednesday night, and was already engulfed in flames when the California Highway Patrol and fire crews got to the scene.
Oakland fire dept. responded and capped the hydrant.
The man, who appeared to be in his 50s, likely died from smoke inhalation in the fire in a four-plex in the 800 block of 47th Street near UCSF Benioff Children's Hospital Oakland, said fire department spokesman Michael Hunt. The victim had only minor visible burns, Hunt said.
The fire broke out Saturday night.
Firefighters responded to the 5900 block of Alhambra Way at about 3 p.m. to find the tree having smashed through a pool/tub room of the house. Rain was especially heavy at the time, said Battalion Chief James Bowron.
The fire was reported about 9:30 a.m. at the single-story structure at 3828 Foothill Blvd.
Oakland Fire Department made short work of a 2-alarm condo-complex fire near the waterfront at Jack London Square Friday night. No one was injured.
