How IMD Alert Marquee Works

Overview

The alert marquee shown on the ELWOIC homepage is NOT directly connected to IMD servers and does not fetch or copy official data automatically. All information displayed is manually entered by the developer for educational and informational purposes only.

How Alerts Are Added

Alerts are manually typed inside a JavaScript file imd-marquee.js where daily alert text is stored in the following format:

const alerts = {
  "2025-11-24": { text: "IMD Alert For Malappuram District: y" },
  "2025-11-25": { text: "IMD Alert For Malappuram District: y" },
  "2025-11-26": { text: "IMD Alert For Malappuram District: y" },
  "2025-11-27": { text: "IMD Alert For Malappuram District: g" },
  "2025-11-28": { text: "IMD Alert For Malappuram District: g" }
};
        

The system then checks the user’s current date and displays the corresponding text. If no alert is available for that date, the message will clearly say that the data is not available.

Why This Matters

⚠️ Please note: The IMD alert displayed in the marquee is entered manually by the developer and does not update automatically. If an alert is updated on IMD today but is not yet manually updated in our system, the marquee will continue showing the previous alert for that date until it is updated.

Example: Consider today is 26/11/2025. IMD officially publishes (at 18:24) the following alert levels:
• 26/11/2025 — Yellow
• 27/11/2025 — Yellow
• 28/11/2025 — Green
• 29/11/2025 — Green
• 30/11/2025 — Green
The developer manually enters these values into the JavaScript file as:
const alerts = {
"2025-11-26": { text: "IMD Alert For Malappuram District: y" },
"2025-11-27": { text: "IMD Alert For Malappuram District: y" },
"2025-11-28": { text: "IMD Alert For Malappuram District: g" },
"2025-11-29": { text: "IMD Alert For Malappuram District: g" },
"2025-11-30": { text: "IMD Alert For Malappuram District: g" }
};

If the next day (27/11/2025) IMD changes the alert for all 5 days to Green, ELWOIC will still show 27/11/2025 as Yellow until the developer manually updates the script.

🔹 This delay does not mean the information is wrong intentionally — it simply means the manual update is pending. ELWOIC always encourages users to cross-check severe weather alerts with official IMD sources. But we try our maximum to update in time and gives you real time updates.




• No IMD servers or links are accessed automatically.
• No copyrighted IMD data is extracted or downloaded.
• ELWOIC does not claim to be an official weather authority.
• Data is manually filled by a student for learning and awareness purposes.

Official Advisory

For verified and real-time alerts, visitors should always rely on the India Meteorological Department (IMD). ELWOIC encourages users to cross-check severe weather alerts with the official IMD sources.
