A robust, vigorous storm rolled into California Thursday into Friday and brought torrential rain, mudslides, power outages, roaring winds and even a tornado.

In the severely drought-stricken state, the rainfall provided some relief. However, thousands were without power as a result of the storm.

As the storm inundated parts of Northern and Southern California, it also produced a tornado Friday morning in South Los Angeles. No one was injured but damage occurred on several blocks from the EF-0 tornado, the National Weather Service in Los Angeles said.

Los Angeles County officials said the rain brought 1.8 billion gallons of water to the region, which they said is enough to support 30,000 residents for one year.

7:55 a.m. Friday: As persistent, heavy rain swamps California, 'pineapple express' trends are appearing across numerous social media outlets. This setup is not that of pineapple express, however, AccuWeather.com Expert Meteorologist Bernie Rayno explains.

"A pineapple express is a continuous surge of tropical moisture extending from near Hawaii all the way into a storm," he said. "While this storm certainly had a tropical contribution at times, it is not being driven by tropical moisture. It was driven by dynamics, or wind."


The storm has brought damaging winds from southern Oregon all the way down into southern California. The winds served as energy and were the true drivers of the storm, not the tropical moisture.

"If this was a true pineapple connection, rainfall amounts would be double what we're seeing now," Rayno said.
