What weather phenomenon is indicated by a “red flag warning” in Mississippi?

A “red flag warning” is specifically issued to alert the public about conditions that are conducive to the rapid spread of wildfires. In Mississippi, this warning indicates a combination of high winds and low humidity, which significantly increases the risk of fire ignition and propagation. During such conditions, even a small spark can lead to catastrophic fires, especially in dry grassy areas or forests.

Understanding this, it becomes clear that red flag warnings are a crucial component of fire weather forecasts, helping to inform both residents and officials of the heightened risks, so they can take necessary precautions to prevent wildfire outbreaks, protect property, and ensure public safety.

The other options pertain to different weather phenomena: severe thunderstorms, heavy rains, and frost advisories are categorized separately with distinct warning systems, aimed at addressing their specific hazards.
