Which weather phenomenon is characterized by both heavy rainfall and strong winds?

The characterization of a weather phenomenon that includes both heavy rainfall and strong winds is best represented by a tropical storm. Tropical storms develop over warm ocean waters and are classified as a type of tropical cyclone that has organized circulation and sustained winds of 39 to 73 mph. These storms are known for producing intense rainfall and can lead to significant flooding, along with damaging winds that can result in power outages and structural damage.

While hurricanes also exhibit heavy rainfall and strong winds, they represent a more severe stage of the tropical weather system, categorized with winds exceeding 74 mph. Thunderstorms do produce heavy rain and can have strong winds, but they are typically short-lived and do not have the sustained wind structure characteristic of tropical storms. Winter storms primarily involve snow or ice and may have wind but do not fit the description of heavy rainfall. This makes tropical storms the most appropriate choice when considering both heavy rainfall and strong winds together.
