Thousands Flee as California, Nevada Wildfires Swell

The Facts

• The states of California and Nevada have reportedly evacuated around 31K people as wildfires expanded rapidly in the two states on Sunday amid a worsening heat wave.

• California's blaze, which lit up Thursday in the city of Highland near the San Bernardino Mountains, has reportedly ravaged more than 20K acres by Sunday.

• Meteorologists said the "Line Fire" conflagration's intensity “helped spawn its own thunderstorms” and lightning, stalling fire-fighting manuevres.
