Angelenos woke up to an unpleasant surprise this morning.
Rain drenched the Southland in water -- up to three inches in downtown, which saw its wettest day of the year.
Two people had to be rescued from a tree near San Fernando Road -- just an hour later a pair of men and their dog had to be saved from the LA River.
Meteorologists have been warning about a particularly torrential El Nino for months now… And where there’s rain, there’s mudslides.
What does that mean for LA? Is our infrastructure prepared to handle the rain -- and the mud?
