Eckari

Active National Weather Service watches, warnings and advisories for a US coordinate or a two-letter state or marine area code - event, severity, certainty, urgency, headline, affected areas and zone codes, and effective/onset/expiry times in UTC. Read at request time, so an empty list means nothing is active. The 5 newest come back by default; detail=full adds the NWS narrative. Use when: Decide whether an active US weather warning affects a location before dispatching or travelling.
