The SPC issues watches for what reason?

The correct choice indicates that the Storm Prediction Center (SPC) issues watches to signal a potential severe weather event may occur. Watches are proactive alerts that inform the public and meteorology community that conditions are favorable for severe weather development in a specified area. This means that while the severe weather has not yet happened, the atmospheric conditions are conducive to its formation, allowing people to prepare and stay vigilant.

In contrast, warnings typically pertain to severe weather that is currently occurring or imminent, while watches serve as advance notice of the possibility of such weather events developing. This distinction is important for understanding how meteorological communication works in terms of preparedness and response to changing weather conditions.
