SAN FRANCISCO (CBS SF) — In a region in the grips of a severe drought the rain totals from a potent atmospheric river were a welcomed relief — nearly a foot of precipitation fell over the last 72 hours on Mt. Tamalpais and more than 10 inches drenched Ben Lomond in the Santa Cruz Mountains.

It may not be a drought buster, but it certainly eased the parched conditions and brought much needed moisture to the Bay Area hills and reservoirs.

“This is great,” said Authur Bosshardt, who was out for a walk in San Anselmo. “It’s what we need. Not much higher, but it’s really needed.”

The welcome rain didn’t stop Oakland resident and artist Zhenne Wood from walking her neighbor’s dog.

“I decided to stay home today and not go anywhere, which is nice,” she said. “And I’m really happy for the rain. I think we needed it a lot.”
