Stable identifier for this precipitation burst; use it for deduplication and historical lookups.
registrationId
string
ID of the webhook registration or subscription that the event belongs to.
recipientId
string
Caller-defined ID that ties the alert back to your internal customer/asset record (can be an anonymous/hashed key to meet GDPR compliance); it must remain unique per geometry because only one registration is allowed for the same area per recipientId, letting you route the alert without storing our registrationId.
timeEpochMillis
number
UTC timestamp in milliseconds that marks when the precipitation is predicted to reach the target centroid.
intensity
enum
Qualitative rate derived from radar reflectivity + sensor fusion.
centroid
object
Geographic center (latitude/longitude) of the impacted area.
distance
number
Meters between the centroid of the precipitation cell and your registration reference point.
