So far, we haven't seen too many storms in southern California since the beginning of the month.

The Pacific storm track has been focused further north, swelling rivers, and creating a rich snowpack in the mountains.

That much is good news for a perennially parched state.

But El Niño's effect has been a bit less positive along the coastline... Powerful waves and heavy rains triggered significant erosion of the coastal bluffs in the northern town of Pacifica.

City officials have declared an emergency and local residents have been forced to relocate from 20 apartments.

For more about the dangers of accelerated erosion, Take Two's Alex Cohen spoke to Lesley Ewing  senior engineer with the California Coastal Commission.
