California Could Flood Like Texas. But Thunderstorms Likely Won't Be to Blame | KQED
Briefly

Flash floods like those recently seen in Texas could happen in California due to climate change, although major thunderstorms similar to those in Texas are unlikely. Localized flooding can occur if conditions align, as evidenced by past events like the atmospheric river in the North Bay that caused fatalities. Compared to Texas, most California localities lack sirens for flood alerts but rely heavily on the weather service for warnings. Some Marin County communities do utilize flood horns or sirens to alert residents to imminent flooding.
"The magnitude of the severity of the flooding absolutely could happen in California, and it is the kind of flooding that we are very concerned about," said Daniel Swain.
"Because our flooding kind of builds and we can see what is coming in," said state climatologist Michael Anderson.
California relies heavily on the weather service for messaging about potential flooding from storms.
Some Marin County communities maintain flood horns or sirens that they sound when flooding is imminent.
