More than 50% of all flood fatalities are vehicle-related. You never know how deep the water is or if the road has been washed away or compromised beneath the water. Don’t risk driving into floodwaters. Turn Around, Don’t Drown!

With a high risk of excessive rainfall issued across southern California on Wednesday, do you know what that means?

Excessive Rainfall Outlook High Risk Days indicate potential for extreme impacts from flash flooding.

For more information about High Risk Days: www.wpc.ncep.noaa.gov/qpf/eroclimo/
A level 4 out of 4 high risk for excessvie rainfall is in place across a large portions of southern California, just north of Los Angeles for Wednesday. High Risk Days are a BIG DEAL. High Risks are only issued by WPC on about 4% of days, but account for one third of all flood-related fatalities and four fifths of all flood-related damages. Graphic showing the WPC Excessive Rainfall Risk Categories: no area/label, marginal, slight, moderate, and high. Each has a description. High risks mean widespread flash floods expected. Areas that don't normally flood could. Lives and property are in greater danger.

A rare High Risk has been issued:
"This will pose a significant threat of flash flooding, landslides, rock falls & mud slides. The greater than normal travel during the Christmas Holiday will potentially expose a larger number of people to these life threatening hazards." -NWS Forecast Discussion
This map shows an Excessive Rainfall Outlook for Wednesday, December 24, issued by NOAA's Weather Prediction Center. It highlights potential flooding risks across California, Nevada, and parts of Arizona. Risk Breakdown by Region The map uses a color-coded scale to indicate the probability of rainfall exceeding flash flood guidance: High Risk (Pink/Purple): This is the most severe category. It is centered directly over Los Angeles and surrounding coastal/mountain areas. This indicates a very high confidence in widespread, life-threatening flash flooding. Moderate Risk (Red): Surrounds the High Risk zone, covering much of Southern California, including areas north toward Santa Barbara and south toward San Diego. Slight Risk (Yellow): Covers a broad area including the Central Valley (Fresno), the eastern Mojave Desert, and Las Vegas, NV. Marginal Risk (Green): Extends across Northern California (near San Francisco/San Jose), the Sierra Nevada, and into western Arizona.

Heavy rainfall will result in flooding of rivers, creeks, streams, and other low-lying and flood-prone locations this week (Dec. 22-26) across portions of California. Mud and debris flows will be possible across foothill and mountain areas, including recent burn scars.
weather.gov
Be prepared for debris flows. Heavy rain can cause debris flows in minutes, potentially burying homes. Areas with low vegetation or recent wildfire burns are especially at risk. Have a plan for your family and be ready to follow instructions from local officials. Listen & watch for rushing water or mud or unusual sounds such as trees cracking or boulders knocking together.

Happy Winter! 10:03am ET today marked the Winter Solstice, the day of the year when the Earth's northern hemisphere is tilted furthest away from the Sun – making today the shortest of the year for those of us north of the equator.
Will wintry temperatures be in your area? 😬

During a flood, water levels & the rate of flowing water can quickly change. You are safest staying indoors or seeking higher ground if shelter isn’t available. If you’re outside when a flash flood occurs, do not attempt to cross flood waters by vehicle or on foot.

You are safest by staying indoors, or seeking higher ground if shelter isn’t available. If you’re stuck outside when a flash flood occurs, do not attempt to cross flood waters by vehicle or on foot."
