Introduction
INMET is the Brazilian official source of meteorological forecasts. It also maintains the ALERT-AS, an weather alert center for the Brazilian territory.
The alerts are broadcasted in the RSS format and there is no official record history of alerts available. Thus, I started to run a daily script to record those alerts and made them available to the public. The record started on September 29, 2025 at 4pm.
Data
The alerts are fetched daily at 1am using the inmetrss R package. After fetching new alerts and updating the database, a parquet file is exported to an S3 storage, available at the link bellow:
https://inmetalerts.nyc3.cdn.digitaloceanspaces.com/inmetalerts.parquetData usage
The parquet data present the alerts in the original structure from INMET. The package inmetrss presents a function to parse the alerts by municipality.
