Update: Holiday Storm Advisories And Watches

A Winter Weather Advisory continues for the Sierra Nevada above 6,000 feet through 10 AM this morning.

Four to ten inches of additional snow accumulation is likely above the 6,000 foot elevation.

An incoming strong storm system around Presidents’ Day (Monday) will bring a period of excessive rainfall to Northern California. The combination of saturated ground, heavy rain, and snow melt will result in large amounts of runoff into rivers and streams.

Significant rises in rivers and streams draining from the mountains can be expected beginning Sunday night. Elsewhere, flooding of poor drainage areas and flood prone creeks and streams will be possible.

Mud slides in areas of higher terrain are also possible, which could lead to road closures and significant travel delays.

A Winter Storm Watch has been issued for the Sierra Nevada, from Sunday morning through late Monday night.

And a Flood Watch has been issued by the National Weather Service for the Mother Lode, the Sierra Nevada and the Northern San Joaquin Valley from Sunday evening through early Tuesday morning.

A Winter Weather Advisory for snow means that periods of snow will cause primarily travel difficulties. Be prepared for snow covered roads and limited visibilities, and use caution while driving.

A Winter Storm Watch means there is a potential for significant snow, sleet, or ice accumulations that may impact travel.

A Flood Watch means there is a potential for flooding based on current forecasts. You should monitor later forecasts and be alert for possible Flood Warnings. Those living in areas prone to flooding should be prepared to take action should flooding develop.
