1201_rebecca_tree_launchWinds reaching nearly 100 mph are wreaking havoc on Los Angeles -- and Eric Dane and Rebecca Gayheart felt it first hand when a giant tree toppled over outside their Beverly Hills home.

Dane and Gayheart were reportedly at home at the time, but didn't get hurt. The tree -- which the LA Fire Department says was 50 feet long and weighed 800 lbs. -- also took down power lines ... so the area was sealed off.

Trees have been knocked down all over town, from Pasadena to Sunset Blvd.

Sometimes living in L.A. really does blow.
