Southern California floods: record tides, closed roads, and a Halloween storm

BREAKING

Record tides flood Southern California

Ocean water along Southern California reached its highest recorded heights this week.

WHAT HAPPENED

Streets under seawater

Hundreds of homes, shops, and roads flooded from Malibu down to San Diego.

ROAD CLOSURES

Pacific Coast Highway closed

Water covered the highway near Huntington Beach and Sunset Beach, reaching knee-deep in spots.

COASTAL TOWNS

Seawall breaches

In Redondo Beach, waves broke over the seawall and pushed water into bars and restaurants.

THE NUMBERS

8-foot tides in San Diego

San Diego's tide gauge topped 8 feet, nearly 1.5 feet above the predicted level.

WHY IT MATTERS

Why the water rose

An extreme El Nino warmed the ocean. Warm water expands and pushed levels to record highs.

THE SCIENCE

Not the moon's fault

This week's tides were not even true king tides. El Nino, not the moon, drove the records.

THE STORM

Halloween storm hits

A Halloween storm added rain. Los Angeles saw its first wet Halloween in 12 years.

THE DANGER

Rain on top of tides

Rain overwhelms drains while high seas block water from escaping. Streets trap the floodwater.

WHAT'S NEXT

Bigger tides coming

True king tides arrive at Thanksgiving and Christmas, 6 to 12 inches higher than this week.

THE WARNING

Water could rise 1 foot higher

With El Nino effects lasting months, record water levels could climb a full foot higher.
