What must be continuously monitored according to the guidelines for Convective SIGMET?

Continuous monitoring of radar is essential according to the Convective SIGMET guidelines, as it provides real-time data about storm development, movement, and intensity. Radar technology allows pilots and air traffic control to observe precipitation patterns, which are critical for identifying hazardous weather conditions associated with convective activity, such as thunderstorms, severe turbulence, and possible wind shear. This information is vital for maintaining flight safety and making informed decisions about altering flight paths or managing air traffic in areas affected by convective weather.

While weather conditions, instrument readings, and air traffic are also important to monitor for overall flight safety, radar specifically provides crucial visual insights into the dynamics of convection-related phenomena that are essential for assessing immediate threats to flight operations.
