It's Fire Everywhere Day apparently, and on top of vegetation fires on the Marin Coast and in up in Santa Rosa and the major wildfire burning near Geyserville, a fire next to I-80 in Vacaville is causing a traffic backup, and another small fire has broken out near I-580 in Richmond.

The Vacaville fire broke out near Cherry Glen Road around noon on Thursday, and as the Chronicle reports it led to the blockage of several lanes of the I-80 freeway in both the eastbound and westbound directions. As of 1:38 p.m., CHP Solano tweeted that all lanes of the freeway had reopened, and the fire was reportedly fully extinguished.

The fire in Richmond broke out around 1 p.m., and KRON 4 reported that it was in the area of the Bay Trail near Point Isabel and I-580. Smoke could be seen wafting out over the Bay and across the East Bay.

Meanwhile, the Muir Fire in Marin County reportedly grew to 50 acres, and the Marin County Fire Department says it is 10 percent contained.

The causes of all these fires remain unknown.
