What are some common indicators of wildfire danger?

The presence of increased temperature, low humidity, and elevated wind speeds are critical indicators of wildfire danger. High temperatures can cause vegetation to dry out, making it more susceptible to ignition. Low humidity reduces the moisture content in plants and soil, increasing flammability. Elevated wind speeds contribute to the rapid spread of fire by carrying embers long distances and fanning flames, making it difficult to control a wildfire once it starts. These conditions create an environment that enhances the likelihood and severity of wildfires, which is why this choice is recognized as the correct indicator of wildfire danger.

In contrast, cool temperatures and high humidity tend to dampen fire risk, as they keep vegetation moist and reduce the chances of ignition. Stagnant air and rain forecasts can also lower wildfire danger since rain helps to hydrate dry vegetation and stagnant air limits the spread of existing fires. Lastly, dense fog and stable weather patterns generally provide a moist environment that reduces fire risk, further distinguishing these options from the critical conditions listed in the correct answer.
