Can you describe what 'Partial County Alerting' is in the SAME specification, and how it differs from storm-based or impact-based alerts?
" Partial County Alerting (PCA)" refers to a system that provides notifications to local law enforcement officials when severe weather threatens their jurisdiction. The term "partial county alerting" emphasizes the fact that the notification mechanism only applies to certain parts of a given county or region, rather than covering the entire area.

Storm-Based or Impact-Based Alarms: Storm-Based or Impact-Based alarms are issued by meteorological offices or emergency response agencies based on specific criteria such as high winds, heavy rain, or lightning strikes. These alarms provide broad notice to the public about potentially dangerous weather conditions and may trigger evacuations or other actions.

 PCA System: A PCA system typically consists of several components, including software applications designed to detect and monitor severe weather events, real-time data feeds from various sources, and user interfaces for accessing and managing the system. When a severe weather event occurs, the software application uses the real-time data feed to identify affected areas within the jurisdiction of the local law enforcement agency. Then, the system sends out alerts to relevant individuals, groups, or organizations who have been identified as being particularly vulnerable to the effects of the weather event.

The main difference between PCAs and storm-based or impact-based alarms is that PCAs focus on providing localized information to authorities who can take immediate action to protect citizens, while storm-based or impact-based alarm systems provide broader warnings and information to the general public. Additionally, PCAs are often programmed to issue alerts at different levels depending on the severity of the threat, while storm-based or impact-based alarms usually do not have this capability.
