Final answer:
Wind speeds of 55 to 73 mph are indicative of a Severe Thunderstorm Warning, not high enough for a Hurricane Warning, and below the criteria for a Tornado or High Wind Warning.
Step-by-step explanation:
Conditions with wind speeds of 55 to 73 mph meet the criteria for a Severe Thunderstorm Warning. These conditions signal the presence of a severe thunderstorm that could cause significant atmospheric disturbances such as strong wind gusts. The wind speed range specified is not high enough to classify as a Hurricane Warning, which starts at a minimum wind speed of 74 mph according to the Saffir-Simpson Scale. It is also below the threshold for a Tornado Warning, which is issued when a tornado has been sighted or indicated by weather radar. Lastly, a High Wind Warning is typically reserved for wind speeds exceeding 58 mph that are not related to thunderstorms.
