Southern Californians took advantage of the President's Day holiday to get in a little beach time, but some were surprised to see the once sandy Cabrillo Beach coastline is now covered in rocks.
The military is funding a coastline study to help determine how El Nino and climate change could impact its facilities and bases close to the ocean.
A strong El Niño is in place in the Pacific. With California in the fourth year of drought, rainfall would be welcome, though it could bring mudslides to areas scorched by wildfire. El Niño conditions will start to decline during the spring.
