Atmospheric River Event Sunday...

When I read that subject line, in an email from the City of South Lake Tahoe, I thought it was some kind of Winter Festival. Not!

The National Oceanic and Atmospheric Administration (NOAA) is forecasting a major Atmospheric River to hit the region this weekend starting on Sunday, January 8th and continuing through Monday, January 9th with widespread flooding expected. NOAA is also forecasting another Atmospheric River arriving in the region on Tuesday and Wednesday, January 10th-11th. NOAA is stating that this event could be similar or greater than the floods of 1997 and 2005 which greatly impacted South Lake Tahoe.

An Atmospheric River is a conveyor belt of vapor that extends thousands of miles from out at sea, carrying as much water as 15 Mississippi Rivers. Each storm can dump inches of rain or feet of snow. NOAA is predicting 6”-8” of rain falling in the Tahoe Basin between Sunday and Monday; if these predictions hold, residents and visitors of South Lake Tahoe need to be prepared.

On Friday, January 6th, we encourage residents to get prepared by doing the following:
Stay home. If you really don’t have to go out, don’t. Even if you can drive well in the snow, not everyone else can. Don’t tempt fate: If you don’t have somewhere you have to be, #StayHomeStaySafe.
Get sand bags. Sand bags are available at the City yard.
Clear storm drains. There are 1,874 storm drains in the city. City crews will be out clearing to clear high priority drains in expected flood areas. Residents can also help by clearing any storm drains in front of their home. Use a shovel or pick to break ice and snow away from storm drains so that water can enter the drains.
Prepare for utility outage. Gather flashlights and replace batteries.
Keep roofs cleared. Snow with high water content is heavy. When it’s followed up by torrential rain, existing snow on your roof will become heavier. Spend Friday and Saturday clearing as much snow off your residential structures before the next storm arrives.
Expect berms. Heavy snow is more difficult to plow and often results in berms in driveways and at street intersections.
Stock up on supplies. People using oxygen tanks need to have battery back-up power on hand. Residents should store up on food, water, batteries, pet food.
Don’t drive through water that is too deep. If flooding occurs, don’t drive through it.
Stay informed. Tune into TV, radio stations, and/or social media for storm updates.
Get the word out. Advise neighbors, friends and family of expected flooding and to plan and prepare.
Emergency Operations. In anticipation of flooding and severe weather, the City has already contacted American Red Cross and prepared its Emergency Operations Teams to be on call and ready to open evacuation centers as needed. Stay up to date with emergency and weather information with the City’s social media accounts. Recreation Center staff are currently working with the Red Cross to have emergency shelter established for residents displaced during the storm. We urge everyone to be prepared. NOAA states this Atmospheric River is one of the largest they’ve seen in many years. Let’s be prepared. Let the excitement begin!

I was a So-Cal born Winter Badass for 8 years! My favorite time was March 1991 (when we were both 8 mos pregnant) and we got 52 inches of snow one week and 72 inches of snow for the month. First time I think I ever called in to work in Palm Springs as "snowed in"! My 4wd cars were troopers down that twisty mountain road every day. Enjoy! Was telling Nick how I like it when the weather influences what you can and cant do... seldom does that down here. But I will say the hills are a beautiful green with our rain.
