LAKE COUNTY, Calif. – A big storm expected to pass over Northern California later this week has the potential to bring several inches of rain to Lake County, and local officials are urging county residents to be prepared.
The National Weather Service has issued a special weather statement for Lake County and other parts of Northern California due to the storm, predicted to arrive on Thursday and continue until Monday.
Forecasters said another “atmospheric river” – described as a plume of concentrated moisture that is between 250 and 400 miles wide – is taking aim at Northern California.
The early December storm that dumped a lot of rain on Lake County and the rest of the region also was attributed to an atmospheric river, as Lake County News has reported.
This latest storm is expected to arrive over northwest California on Thursday, spreading east and southward by Friday, when the most rain is forecast across the lower elevations. Snow also is predicted at the 5,500-foot elevation level, rising to more than 7,000 feet over the weekend.
Forecasters said their models for precipitation are still variable in terms of amount, but this storm is expected to bring a “decent” amount of rain, with amounts estimated between 1 and 4 inches in the Sacramento Valley and 4 to 10 inches across the foothills and mountains.
Estimates for rainfall in much of Lake County averages at about 5 inches, with some of the mountain areas likely to get more, according to the detailed forecast. Updates will be posted as the storm track becomes clearer.
“That's a lot of rain for Lake County,” Lakeport Public Works Director Mark Brannigan told the Lakeport City Council on Tuesday night, as he gave them an update on the forecast.
Brannigan said in the city of Lakeport extra staff will be on standby this week in case the predictions for storm impacts hold true. They've always been cleaning storm drains and have sandbags on hand.
He said they are urging people to be ready, “And we're going to be doing the same.”
The storm also is forecast to bring winds with it. In Lake County, wind gusts are anticipated to range from between 20 miles per hour in the Lakeport area to as much as 55 miles per hour on the Northshore on Thursday night, according to the forecast.
Temperatures for the rest of the week and into early next week around Lake County are forecast to drop into the low 40s at night and the high 60s during the daytime hours.
Most of California remains in severe drought conditions, according to the latest version of the US Drought Monitor, which estimates that more than 50.4 million people are impacted by drought conditions across the Western United States.
In Lake County, Clear Lake's level on Tuesday was just under 2.90 feet Rumsey, the special measurement for the lake.
While that's well above the 0.54 feet Rumsey measurement on Feb. 3, 2014, it's also about half of the lake's recorded level on Feb. 3, 2013, and close to the 2.94 feet Rumsey recorded on Feb. 3, 2012, according to US Geological Survey records.
Brannigan told the council Tuesday that, because of the low lake level, the impact from heavy rains should dissipate quickly, as it did the last time.
Due to the anticipated rain amounts and wind speed, area residents are urged to be prepared for the possibility of small stream flooding and power outages.
Lake County Office of Emergency Services Manager Marisa Chilafoe said residents should have emergency supply kits ready and available in case of power outages, keep trees trimmed and yard debris to a minimum, protect areas vulnerable to flooding with sandbags, and by securing items such as lawn furniture, trash cans, hanging plants, or anything else that can be picked up by the wind and become a projectile.
Pacific Gas & Electric (“PG&E”) cautions residents that if you see a downed power line, assume it is energized and keep yourself and others away. Call 911 immediately to report the location of the downed line then 1-800-743-5002, PG&E's 24-Hour Emergency and Customer Service Line. Please keep away from flooded areas and downed trees, as these areas could be hiding an energized power line.
