Heavy rains are poised to cause the worst flooding along the Russian River in Guerneville in Northern California in more than 20 years.
Here is what you need to know:
Q: What is the outlook?
- About 4,000 people living in about two dozen areas near the river were ordered to evacuate Tuesday as the river started to flood. It’s expected to crest at 46.1 feet — more than 14 feet above flood stage — Wednesday night.
- Some areas north of the river got nearly 10 inches of rain as of Tuesday. The National Weather Service said the new storm produced more than a foot of rain in the hills above Healdsburg.
Q: How about burn areas?
- Sonoma County was hit by devastating wildfires in 2017 that burned thousands of homes and charred many hillsides and canyons.
- Officials say they are also concerned about mudslides, especially in the hillside neighborhoods along the river and areas ravaged by recent wildfires. One debris flow sloshed across a roadway in the Monte Rio area on Tuesday evening, but no one was injured.
