In dispatch terminology, which code indicates a significant event due to weather?

The correct code indicating a significant event due to weather in dispatch terminology is x90W. This code is specifically designated to address incidents where weather conditions play a crucial role, making it clear to dispatchers and responders that the situation is influenced by meteorological factors. Using this code enables quick and effective communication regarding weather-related emergencies, ensuring that appropriate resources and responses are allocated for safe and efficient management of the event.

Each of the other codes serves different purposes within the dispatch system, specifying various types of incidents or statuses, but none directly reference weather-related events like x90W does. The specificity of the code allows for enhanced situational awareness among dispatch and response teams.
