What do the Red, Orange, Yellow and Green alert colours mean?
These follow the India Meteorological Department's official colour code. Red means take action - a severe hazard is expected. Orange means be prepared - a significant hazard is likely. Yellow means be aware - watch conditions closely. Green means no warning is currently in effect for that state.
How often are alerts updated?
This page checks the IMD CAP feed every 30 minutes. An alert is removed automatically the moment its own official validity window expires - nothing on this page is manually curated.
How do I subscribe to alerts?
Click "Alert me" on any alert card, or on your state in "alerts near me", enter your email, and confirm via the link we send you. You'll then get an email whenever IMD issues a new Red or Orange alert for that state - Yellow alerts don't send an email. Every notification includes a one-click unsubscribe link.
Why state-level alerts and not my exact district?
IMD's official alert feed itself reports at meteorological-subdivision/state level, not district level - this page shows exactly the area IMD names in each alert, nothing more precise than the source data actually supports.
Where does this data come from?
Directly from the India Meteorological Department's official CAP (Common Alerting Protocol) 1.2 feed - the same public-domain standard used by emergency alerting systems worldwide.
Alerts on this page come directly from the India Meteorological Department's official CAP (Common Alerting Protocol) feed - the same standard used by emergency alerting systems worldwide. This page is informational; in a genuine weather emergency, always follow official IMD and local authority guidance directly.
What is a Weather Alert & Why Should You Get Warnings?
A weather alert is an official warning from the India Meteorological Department (IMD) that a specific kind of severe weather, heavy rain, a heatwave, a cyclone, a cold spell, is expected in a particular state within a set time window. IMD uses a four-colour system: Green means no warning is in effect, Yellow means be aware and watch conditions, Orange means be prepared for a likely significant hazard, and Red means take action, a severe hazard is expected. India's geography makes this matter everywhere at once: a Himalayan state can sit under a Red snow alert the same week a Rajasthan district is under an Orange heatwave warning and a Bay of Bengal state tracks a forming cyclone, which is why a single national summary never tells the whole story the way a state-by-state alert does. IMD has issued official forecasts and warnings since 1875, one of the oldest meteorological services in the world still operating today.
How Weather Alerts Are Issued & What Each Level Means
IMD assigns a colour to each state or meteorological subdivision based on how severe the expected hazard is, then publishes it through an official CAP (Common Alerting Protocol) feed, the same open, structured alerting standard emergency systems worldwide use, which is exactly what this page pulls from directly, refreshed every 30 minutes. An alert isn't a single blanket "bad weather" label, each one names a specific hazard type, heavy rainfall, heatwave, cyclone, cold wave, fog, thunderstorm, and a specific area and time window, so two Orange alerts on the same day can mean genuinely different things depending on what's actually expected. Because IMD's feed reports at state or subdivision level rather than by individual district or city, this page shows exactly the area IMD itself names in the alert, nothing invented at a finer resolution than the source data actually supports. An alert also disappears automatically the moment its own official validity window ends, nothing here is manually curated or left up after it's no longer current.
How to Interpret & Use Weather Alerts for Decisions
Green needs no special action, normal day. Yellow means it's worth checking the forecast again before finalising outdoor plans, nothing drastic yet. Orange is the level where real preparation makes sense, rescheduling non-essential travel, securing anything that could be affected, checking on anyone in the household who's more vulnerable to the specific hazard named. Red means the hazard is expected to be severe enough that avoiding unnecessary exposure altogether is the safer choice, this is the level local authorities most often act on directly, adjusting schools or transport in the affected area. Children, older adults, anyone with a chronic health condition, and anyone whose work happens outdoors, construction, agriculture, street vending, delivery riding, generally face the highest real risk from any given hazard level, worth factoring in beyond just the colour itself when deciding how seriously to treat a given alert.
Where to Check Alerts & Best Monitoring Practices
This page pulls directly from IMD's own official CAP feed and refreshes every 30 minutes, so checking here during an active Orange or Red alert gives a current, not stale, picture without needing to separately visit IMD's own site. IMD's own website (mausam.imd.gov.in) remains the most detailed official source, including the underlying forecast discussion behind a given alert, worth checking directly for anything genuinely high-stakes. During an active Yellow alert, a normal daily check is enough; during Orange or Red, checking again every few hours as the situation develops is worth the habit, especially if the alert covers a state you're travelling to or from. Subscribing to email alerts for a specific state, available directly on this page, is a simpler way to catch a new Red or Orange alert the moment it's issued, rather than needing to remember to check manually at all.
Why Weather Alerts Matter: Real Decisions, Real Risk
Health and safety impact: Extreme heat and cold are genuine, well-documented health risks in India, not just discomfort, heatwaves in particular are treated as a serious hazard by India's own disaster management authorities, and the risk concentrates heavily in specific groups: young children, people over 60, anyone with an existing heart or respiratory condition, and outdoor workers who can't simply stay indoors during the hottest or coldest hours. Fog and heavy rain carry a different, more immediate risk, reduced visibility and flooded or waterlogged roads are a real factor in road accidents and traffic disruption during winter fog season in North India and during intense monsoon spells nationwide. A cyclone or severe flood warning is the level where evacuation guidance from local authorities, not just this page, becomes the thing to actually follow, since a Red-level coastal alert reflects a genuinely serious, potentially life-threatening hazard rather than a routine weather update. Post-flood periods are also when waterborne and vector-borne illness risk genuinely rises in affected areas, a reason public health messaging around a flood or heavy-rain Red alert often extends beyond the rain itself into the days that follow.
Daily life and logistics impact: Weather alerts translate into real, practical decisions well before anything dramatic happens, a household deciding whether an outdoor event goes ahead, a school deciding whether to hold outdoor activities, a commuter deciding whether to leave earlier because fog or heavy rain is likely to slow traffic, a farmer timing field work around a coming heavy-rain or heatwave warning. Businesses with outdoor operations, construction, logistics, delivery, agriculture, treat an Orange or Red alert as a genuine planning input, adjusting work hours or pausing outdoor tasks rather than treating the warning as background noise. None of this requires waiting for an official closure announcement, checking this page before finalising a day's plans during an active alert is simply a more current, direct read than waiting to hear secondhand that schools or offices have adjusted their own schedule.
