What information is contained in a CONVECTIVE SIGMET?

1. Heavy rain and low visibility

2. Tornadoes and hail 3/4 inch or greater in diameter

3. Severe wind shear and turbulence

4. General thunderstorm activity over the region

The correct answer is: Tornadoes and hail 3/4 inch or greater in diameter

A CONVECTIVE SIGMET is specifically designed to provide information about significant convective weather phenomena that could impact aviation. It particularly highlights severe weather conditions that are not adequately described by general SIGMETs. The correct information contained in a CONVECTIVE SIGMET includes reports of tornadoes, hail of 3/4 inch or greater in diameter, and severe thunderstorms. This is crucial for pilots as it indicates hazardous conditions that could pose a serious threat to flight safety. While other choices mention important aspects of weather that should be monitored, such as heavy rain, low visibility, severe wind shear, turbulence, and general thunderstorm activity, they do not encompass the particular severity and specific weather phenomena that a CONVECTIVE SIGMET covers. Therefore, these options do not fully represent the critical information that pilots receive concerning severe convective activity.
