Strong and potentially damaging winds will lash away at mountain, valley, coastal and urban areas of Los Angeles County Monday and Tuesday morning, according to the National Weather Service.
Following a dry cold front, the winds will pick up Monday afternoon and blow in a west-to-northwest direction, then strengthen as they turn northerly Monday evening and Tuesday morning, said an NWS statement.
