With parts of Los Angeles County still smoldering from wildfires, the expected rain this weekend would seem like a welcome relief. But how the rain falls could make the difference between a disaster respite or a disaster repeat.

The death toll from wildfires raging near Los Angeles has risen to 28, authorities said Tuesday, as new fires prompted evacuations near San Diego.

Rain brought much needed aid to the Los Angeles firefight, moving the fires surrounding the city closer to containment.
