Watch for flood/debris issues around burn areas Sun/Mon

The substantial amount of water delivered by these early-season storms will be primarily beneficial (likely ending fire season across NorCal), but high rain rates could also bring some flood/debris flow problems on Sun/Mon, esp. near wildfire burn areas. #CAwx#CAfireQuote Tweet

Daniel Swain@Weather_West · 1h Models now targeting late Sun into Mon period for potentially strong #AtmosphericRiver event in northern and/or central CA. Ensemble mean brings strong AR conditions. Worth noting that control run brings even more intense conditions, but is at upper end of ensemble envelope.#CAwx8:24 AM · Oct 20, 2021·Twitter Web App
