gusty

Forecasters had warned that a “monsoonal surge” kicking off Saturday would bring a strong chance for thunderstorms that could create gusty winds, dangerous dry lightning and even some brief downpours.

That monsoonal pattern could bring localized gusty winds, minor flooding, debris flows in burn scars, as well as lightning that could spark fires.

Veterinarians and engineers have studied how a barn owl flies so smoothly in gusty winds, and discovered wings act like a suspension and stabilise the head and torso when flying through disturbed air.

Frequent lightning, large hail and gusty winds are additional hazards that would bring transport disruption.

The combination of high temperatures, gusty winds, low humidity, and dry vegetation has created dangerous conditions, fuelling the fire's swift advance, park officials said.
