Why a dying hurricane might be California's next great threat

What The Next Hurricane Will Do To California · 15:40 · Video: Insane Curiosity · Watch at the source

In short: California is rarely hit by hurricanes, but Tropical Storm Hilary proved that even a weakening cyclone can cause catastrophic damage. This documentary explores how shifting climate conditions could turn these storms into severe inland flooding events.

Typically, California's cold coastal currents and wind shear act as natural barriers that dismantle tropical cyclones before they landfall. However, during El Niño cycles, these protections can shift. The film examines the 1858 historical record of hurricane-force winds in the state to understand how such events occur.

The primary danger may not be wind but water. Because California is built for drought, a storm like Hilary—which dropped more than an annual rainfall average in one day in D.Valley—can trigger debris flows and massive flooding. The documentary highlights the specific risks posed to Southern California's canyons, burn scars, and urban infrastructure.
