Tech: These photos show how Southern California has been devastated by mudslides that killed at least 13 people

A powerful storm unleashed destruction in Montecito, Santa Barbara, on Tuesday.

At least 13 people have died from massive mudslides in a wealthy Southern California region early Tuesday morning.

A heavy storm triggered flash floods and unleashed debris in Montecito, Santa Barbara, around 2.30 a.m. local time (PST), the LA Times reported.

As Santa Barbara County Sheriff Bill Brown told reporters on Tuesday night: "The best way I can describe it is it looked like a World War One battlefield."

Take a look at the harrowing scenes below.

A heavy storm in the region triggered flash floods and unleashed debris. The region was especially vulnerable after a series of wildfires. This smashed car on Montecito's Hot Springs Road, is a small part of of the destruction in the area.

Trees were torn from their roots, houses and cars were destroyed, and people were covered in mud as debris surged down empty streets. This woman was caught up in the chaos, and had to be rescued from a collapsed house.

As of Tuesday night, at least 25 people were injured, and some 300 others trapped in their homes because of the storm.

People's cars got smashed in by fallen trees, which were knocked in the wind and mud flows.

Debris flowed into car parks. The car on the left, covered in debris, is floating on a mixture of mud and water.

Some cars were left floating along flooded freeways, while emergency services did their best to get to affected areas.

The Union Pacific Railroad — which operates routes from Chicago to New Orleans — was also blocked by mud.

Train tracks between Santa Barbara and Oxnard, a city west of Los Angeles, were closed, Amtrak's Southern California service tweeted on Tuesday night.

Locals did their best to get around despite all the obstacles.

Celebrities including Ellen DeGeneres, Rob Lowe and Patrick Stewart also live in the wealthy Santa Barbara area.

Search and rescue operations continued through the night. Some agencies are planning more aerial operations, like the one below, in the morning to get more trapped people out of their homes.
