Floods isolate 2 California towns, storm dumps snow in West

GUERNEVILLE, Calif. (AP) — Two communities in Northern California's wine country were accessible only by boat Wednesday after a rain-swollen river overflowed its banks following a relentless downpour, inundating an already waterlogged region as snow from the storm system piled up from California's mountains to Montana.

The small city of Guerneville north of San Francisco "is officially an island," with the overflowing Russian River forecast to hit its highest level in about 25 years, the Sonoma County Sheriff's Office said in a statement.

"Nobody is coming or going from the Guerneville area at this time," said sheriff's Sgt. Spencer Crum.
