Advisories are issued for what type of threats?

The correct choice identifies that advisories are generally issued for threats that are dangerous but may not be classified as life-threatening. Advisories serve as alerts to inform the public or relevant authorities about potential hazards that may require caution, preparedness, or precautionary measures. This means that while the situation may pose risks to safety or property, it does not rise to the level of an emergency that would justify a more urgent alert such as a warning.

Other options present scenarios that usually require different types of alerts. For instance, life-threatening situations often call for warnings, which convey more immediate action and higher urgency. Minor weather changes, while they might impact daily activities, typically don’t warrant advisories. Severe and catastrophic events would also necessitate warnings or emergency declarations, as these represent significant threats to life and safety. Therefore, the context of advisories specifically aligns with situations that are indeed dangerous but not necessarily at the critical level where immediate action is needed.
