Authorities across Burbank and Glendale said the storm did not adversely affect the area.
At Bob Hope Airport, spokesman Victor Gill said the rain-soaked tarmac did not result in any delays to morning and afternoon flights, and operations throughout the facility were mostly unaffected by the storm.
“There was a shower coming down, but everything was pretty normal,” he said.
Burbank police reported three accidents between midnight and 4 p.m., though Sgt. Travis Irving said they were not likely the result of the weather.
There were six accidents Monday in Glendale, a normal amount that officials said was not related to wet conditions on the roads.
Rain started late Sunday night and, by 10 a.m. Monday, had dropped nearly half an inch across the region, heralding the unofficial start to winter, though the season officially begins Sunday.
The wet weather followed a record-setting cold front across Southern California, said Stuart Seto, a weather specialist with the National Weather Service in Oxnard.
“The morning lows were a few degrees colder than normal,” he said. “But it was the daytime temperatures that were significantly colder.”
In Burbank, officials recorded a low of 40 degrees Sunday — one degree colder than average — but a daytime low of 55 degrees that same day, 13 degrees lower than the average temperature for that time of year, he said.
Across the nation, temperatures have hovered above what is normally recorded.
The average national November temperature of 44.5 degrees was 2 degrees higher than average, and from January to November, the average temperature of 54.9 degrees was 0.3 degrees above normal, according to records kept by the weather service.
