What is the typical forecast period for a CWA?

The correct choice identifies that the typical forecast period for a Convection Watch Advisory (CWA) is within the next 2 hours. This period aligns with the nature of CWAs, which are intended to provide timely and short-term guidance about the potential for convective weather, such as thunderstorms. CWAs are typically issued in response to rapidly developing weather phenomena, making a focus on the near term essential for effective planning and safety considerations.

The emphasis on a 2-hour window allows meteorologists and the aviation community to proactively prepare for significant weather occurrences, as these events can impact flight operations quite suddenly. This time frame strikes a balance between providing early warning and maintaining relevance to the fast-changing weather conditions associated with convection.
