San Leandro Rainfall Totals

SAN LEANDRO, CA — The wild weather is in our rearview mirror, but it left a mark on San Leandro and the East Bay.

Mount Diablo saw more than 8 inches of rain over the past two days, the weather service said Monday morning. The Oakland Airport saw 4.44 inches of rain.

It's "been a memorable past 24 hours for the Bay Area as the long-talked-about atmospheric river rolled through the region," the weather service said before dawn Monday. "We literally have gone from fire/drought conditions to flooding in one storm cycle."

San Francisco saw its wettest October day ever and its fourth-wettest day overall since the Gold Rush, according to the weather service.

The storm was dubbed both an atmospheric river and bomb cyclone.

Atmospheric rivers are "relatively long, narrow regions in the atmosphere — like rivers in the sky," according to the National Oceanic and Atmospheric Administration.

A bomb cyclone occurs when a storm experiences bombogenesis, meaning it rapidly intensifies over a 24-hour period, according to NOAA.

The weather is expected to start to clear up Tuesday, according to the weather service. Temperatures are forecast to return to the 70s later this week.
