Why the weather created a perfect storm scenario in the California wildfires


The California wildfires, as of late Friday night, have claimed 36 lives and thousands of buildings.

As was the case last November during the Gatlinburg fires, the weather created a 'perfect storm' scenario on the west coast.

May through September is usually the driest point in the year in San Francisco, averaging around 0.72" of rain in that four month span. This year, however, San Fran got only 0.27" of rain in those four months.

Dry brush preceded the 'Diablo winds' which then exacerbated the fires and made them the national headline that they are now.

WATCH below to see how the Diablo winds interact with the California landscape:

High pressure in the Intermountain West sits in a favorable position for fire growth. Clockwise winds around high pressure come over the Sierra Nevada and spill into the canyons. This hot, dry, gusty winds allows the fire to fan out and spread to a wider path.
