Tornado Response

The best response to a tornado-like occurrence, such as a “landspout” (though rare here) depends on where you are. Outdoors, find shelter quickly, or lie flat in a low area like a ditch or ravine and protect your head and neck. Avoid areas with trees. Indoors, follow advice from the Federal Emergency Management Agency for single- or multilevel structures:

Hillside Slippage

One of several tarped and K-railed hillside homes in the Baldwin Hills area of LA is shown.

       Wednesday, 10 AM, 3/29 - SLIDE AREAS: Past weeks' rains created saturated hillsides Citywide. Response/recovery agencies are monitoring slides in various locations - including hillside communities in the Baldwin Hills area, where in the interest of personal safety, a few homes were yellow-tagged for limited access. Impacted homes and hillsides continue to be evaluated for stability. 

Days after the rains, a large (near-half acre) slide developed from heavily saturated soils in the Pacific Palisades neighborhood resulting in both affected homes being declared unsafe for dwelling, pending further City inspection.

Wednesday AM, an additional slide during morning rains caused ~8,000 square-feet of mud to slide towards homes in the Beverly Ridge area - south of Mulholland Drive - blocking driveways. No homes were tagged.     



​ Recognize warning signs of a potential landslide. Fences, retaining walls, utility poles, or trees tilt or move. Widening cracks appear on the ground or on paved areas such as streets or driveways. Listen and watch for rushing water, mud, or unusual sounds.

Signs of a Slide

Listen AND watch for other warning signs, such as: mud buildup at the base of hills, widening cracks in outside walls or paved areas, sticking doors, newly broken utility lines, and new pools of ground water.
