What’s the longest stretch of rain L.A. has ever had — and could this week come close? An atmospheric river is set to roll in late Thursday, with another big wave Saturday that could bring heavy rain, flooding, and debris flows for up to four straight days. 🌧️ Downtown could see 2.5 inches by Sunday, and even more in the mountains. But forecasters say Saturday’s storm is a wild card — it could pour or just drizzle. So, will this be the longest streak ever? No. Back in January 1980, Los Angeles saw 12 straight days of rain. vid by @tomexploresla #LAWeather #RainInLA #AtmosphericRiver #CaliforniaStorm #LAtimes
