The second of back-to-back atmospheric rivers, which unleashed heavy rain across Northern California this week killing two people, was set to dampen Southern California through Friday morning. And a potentially more powerful system could douse the Southland before or around Valentine’s Day, heightening concerns for recently burned communities in Los Angeles County. There is a 30% chance that there could be high amounts of rain between Feb. 12 and 15, Ryan Kittell, a meteorologist with the National Weather Service’s Oxnard office, said Thursday. That’s up from a 20% chance that was forecast a day earlier.
