If an alert covers your area
Every alert
- Do what the alert's instruction says, and follow the district administration.
- Tell neighbours, the village council or the nearest post, especially people without a phone.
- Check the issuing agency for updates: an alert can be extended, updated or cancelled.
- Ignore forwarded messages that do not name an official source.
Thunderstorm and lightning
- Go indoors into a pucca building or a closed vehicle when you hear thunder.
- Keep away from open fields, tall trees, poles, metal fences and water. Get out of boats and ponds.
- Do not use corded phones or touch plumbing; unplug appliances.
- Caught in the open: crouch low with your feet together. Do not lie flat.
Heavy rain and floods
- Do not walk or drive through moving water; keep away from rivers, drains and landslide-prone slopes.
- River status for border rivers and what to do: flood page.
Sea, coast and heat
- Fishers: do not go to sea when IMD or INCOIS warn. Sea state and boundaries: fishers page.
- Heat: safer hours and first aid on the heat page.
Lightning and flood steps adapted from guidance published by the National Disaster Management Authority and its flood do's and don'ts.

From the OASIS Common Alerting Protocol 1.2, the format SACHET uses. The issuing agency chooses these words; Trinetra never changes them.

How this page works
Trinetra reads SACHET's public feeds (all-India and 29 state and union territory feeds) and each alert file, and keeps alerts that cover one of the districts on an international land border or the coast. The district list is derived from OpenStreetMap; map boundaries are not authoritative. Text is shown exactly as issued. Only the field labels ("Headline", "Valid until") can be switched to Hindi, Bengali or Assamese, and those translations are drafts that need local review.
This page updates when Trinetra's pipeline runs, so it can be hours behind SACHET; whether an alert is in force is worked out on your device's clock. Some alerts describe their area only as a count ("9 Mandals") and cannot be placed in a district; they are not shown here, so check SACHET for your state too. Full method: SANDESHA.
