California storm: LA Mayor issues local state of emergency as atmospheric river pounds region

On Monday, Los Angeles Mayor Karen Bass issued a local state of emergency as a powerful storm continued to hammer down on Southern California as the risk of life-threatening flooding remains for a greater portion of the area with constant moderate to heavy rainfall.

Mayor Bass said the emergency declaration will make sure the city will have the required resources during the storm and the storm’s aftermath. This comes one day after Gov. Gavin Newsom declared a state of emergency for eight California counties. 

Bass noted first responders across the city are fully prepared for the unprecedented weather conditions and that Saturday into Sunday marked the 10th wettest day in the history of the city. City crews have been working around the clock and several rescues have taken place. 

By Monday morning, the storm had already dropped more than 10 inches of rain in Woodland Hills, according to the National Weather Service. Bel Air received nearly 10.6 inches, while Beverly Hills received more than 7 inches. Some areas in the Santa Monica Mountains received nearly 11 inches.

As of 4 p.m. Monday, county storm water facilities captured 1.3 billion gallons of water, which can serve 32,800 homes for a year. 

As of 11:30 a.m. Monday, the Los Angeles Police Department had responded to 65 traffic collisions resulting in injuries. Meanwhile, the LAFD responded to over 130 flooding incidents, 49 mud and debris flow cases, extinguished half a dozen structure fires, conducted several water rescues, and managed a 132% increase in automatic alarms. 

NOAA’s Weather Prediction Center (WPC) warned that the ongoing situation will continue to produce catastrophic flash and urban flooding in Los Angeles, which remains under a rare "high risk" of flash flooding.

The "high risk" is the highest rung on NOAA's flash flood threat scale and is only issued under the most dire of flooding forecasts.

The latest storm is the second atmospheric river to strike the region in recent days. Moderate to heavy rainfall has been constant since Sunday evening and remains ongoing across the Southland. The atmospheric river event is expected to last through late Tuesday morning. However, rain chances linger over the next few days and should taper off in time for the weekend.
