Los Angeles mayor: 'This storm continues … take precautions'
"This storm continues -- and that means we still need Angelenos to take precautions," Los Angeles Mayor Karen Bass warned Tuesday.
Periods of rain will continue Tuesday creating dangerous conditions on the roads and increasing the chance of mudslides and flooding, Los Angeles Fire Department Chief Kristin Crowley said.
No fatalities have been reported in LA, Bass said.
Crews have responded to 307 mudslides and 257 fallen trees, Crowley said.
If you must go outside, use caution, Crowley warned. Slow down if driving and always be on the lookout for downed power lines and trees, she said.
The mayor commended residents who have checked on each other in hard-hit communities and stressed that everyone should check on their neighbors.
The "historic" rain is expected to taper off late Tuesday night, National Weather Service meteorologist Ariel Cohen said.
There’s a chance for more atmospheric rivers this spring, Cohen said.
Los Angeles averages 14.25 inches of rain for an entire year. So far this year, LA has recorded nearly 11 inches of rain, or 75% of the city's annual rainfall.
And the rain is still falling. As of Tuesday morning, the three-day rainfall totals have climbed to: 12.2 inches in San Bernardino County; 12 inches in Bel Air in Los Angeles County; 9.4 inches in Santa Barbara County; 8.7 inches in Ventura County and 7.6 inches in downtown Los Angeles.
