Build a dispatch rule that triggers pre-storm crew mobilization specifically on 'Winter Storm Warning' events (not 'Watch' or 'Advisory') pulled from the api.weather.gov alerts feed.

Steps
Query /alerts/active for the relevant area/zone and parse the exact 'event' string returned in each alert's JSON-LD properties
Match dispatch triggers against the literal string 'Winter Storm Warning', distinct from 'Winter Storm Watch' and 'Winter Weather Advisory'
Use the alert's 'severity' and 'certainty' fields as secondary signals, not just the event name, when deciding mobilization thresholds
Test the matching logic against historical/sample CAP payloads to confirm it doesn't fuzzy-match all 'winter storm'-containing event strings to the same response tier
Log which specific event type triggered each mobilization decision for after-action review
Known gotchas
Fuzzy string matching on 'winter storm' alone will also catch Winter Storm Watch (lower confidence, earlier lead time) and treat it the same as a Warning — these carry materially different operational meaning and shouldn't trigger identical crew-mobilization responses
NWS event-type taxonomy can include region-specific or evolving product names — confirm current valid event-type strings against the API rather than hardcoding a list that could go stale
A Warning's issuance does not guarantee it's already in effect — check the 'effective'/'onset' timestamp before mobilizing crews for a future-dated event
