What does THUNDERSTORM CONDITION I (T1) indicate?

1. A thunderstorm is within 10 NM

2. A thunderstorm is within 25 NM

3. No thunderstorms are nearby

4. Thunderstorms are expected after 48 hours

The correct answer is: A thunderstorm is within 25 NM

THUNDERSTORM CONDITION I (T1) indicates that a thunderstorm is within 25 nautical miles (NM) of the area in question. This condition serves as a crucial alert for boaters, as it signifies the potential for hazardous weather, including lightning, strong winds, and heavy rain that can affect safety on the water. Recognizing this condition is essential for making timely decisions about seeking shelter or taking other precautions to ensure safety. The range of 25 NM is significant because it allows those on the water enough time to prepare and respond appropriately, while also being close enough that the effects of the storm could be felt. This awareness enables boaters to adhere to safety practices and navigate accordingly to avoid dangerous situations. Understanding thunderstorm conditions helps in promoting safe boating practices and is vital for effective emergency management in marine environments.
