Colder storm blunts Truckee River flood threat
December 2, 2012
RENO (AP) – A powerful storm delivered more snow and less rainfall Sunday to the Sierra than forecast, blunting the flooding danger on the Truckee River in California and Nevada, forecasters said.
Gary Barbato, a hydrologist with the National Weather Service in Reno, said the colder-than-expected storm caused snow levels to drop earlier and lower in elevation than forecast.
That’s welcome news for those living and working along the Truckee, which flows more than 100 miles from Tahoe to Nevada’s Pyramid Lake near Reno, he said.
“It could lower the flood threat on the Truckee River,” he told The Associated Press on late Sunday morning. “I’m not sure by how much yet. Maybe dramatically, but we’ll have to see.”
Barbato said his agency’s flood forecasts would be revised later Sunday afternoon. The weather service originally called for major flooding Sunday around Truckee, Calif., and for minor to moderate flooding Sunday and Monday around Reno.
At Truckee, 30 miles west of Reno, city officials were focusing on snow removal Sunday afternoon instead of flood control after the town received 4 to 5 inches of snow in the morning, said Assistant City Manager Alex Terrazas.

As of Sunday morning, the river was flowing at 3.8 feet near the Sierra town and was expected to crest at 5.4 feet at 4 p.m. Flood stage is 4.5 feet. Dozens of homes and businesses are located along the river in the town of 16,000.
