What is a climatic waterway?

.FOR CALIFORNIANS it seemed like remembrance. In 2015 a ceremony of hurricanes, fuelled through atmospherical waterways, gotten rid of at least 21 individuals and also caused almost $5bn-worth of damages around the condition. On February 4th this year the exact same type of hurricane once again created chaos.

Hurricane-strength winds buffeted the main coastline near Large Sur. In Los Angeles celebs were soaked as they came to the Grammy honors’ ceremony. Residences in the Hollywood Hillsides were dealt with in mud.

A minimum of 3 individuals have passed away. What are actually atmospheric waterways, and are they a threat beyond The golden state?
