PACIFICA (KRON) — Even though the worst of this week’s storm is over, officials are still warning Bay Area residents of dangerous waves along the coast.

The National Weather Service issued a High Surf Warning Thursday that will be in effect until 2 p.m.

KRON 4’s Will Tran spent the morning in Pacifica where the entire pier is wet, but not because of the rain.

Giant waves up to 20 feet high slammed the pier overnight and into Thursday morning.

Officials are warning swimmers and beach-goers of the large and powerful waves, saying that the water is too dangerous to venture into.

A series of El Nino-fueled storms hit the Bay Area this week, bringing much-needed water to drought stricken California.STORMTRACKER 4: Track the storm yourself
