IMD weather alert today: ‘Red’ alert for heavy rains in Keralam, Tamil Nadu, ‘severe’ cyclone to hit Andhra on Oct 28

A depression over the East Central and adjoining Southeast Bay of Bengal is strengthening quickly. The IMD expects it to become a Deep Depression on October 25, then recurve west-northwestwards. This matters because the system is forecast to intensify further before reaching India’s east coast.

By October 27 morning, it is likely to become a severe cyclonic storm over the west-central Bay of Bengal. The system is projected to peak as a very severe cyclonic storm and reach the Westcentral Bay near the Andhra Pradesh coast by October 28 morning.

Landfall is expected between Bapatla and Visakhapatnam along the Andhra Pradesh and Yanam coasts during the forenoon of October 28. The IMD forecasts maximum sustained winds of 115–125 kmph, with gusts up to 140 kmph. Rainfall warnings extend from October 26 to 29.

Weather alerts communicate the seriousness of expected rainfall. In general IMD usage, a red alert means extremely heavy rain is likely and people should take urgent precautions. An orange alert indicates very heavy rain with a risk of disruption. A yellow alert means heavy rain is possible and residents should stay watchful. These meanings extend the rainfall descriptions given in the article.

For example, Malappuram, Kozhikode and Wayanad had red alerts for October 25. Idukki and Palakkad were placed under red alert for October 26. Kerala districts including Thrissur and Kannur received orange alerts, while several southern districts received yellow alerts.

The alerts do not predict identical conditions everywhere. They identify areas needing different levels of readiness. The IMD also issued red alerts for Tamil Nadu, Puducherry and Karaikal. Residents should follow local official instructions, especially where intense rain may affect travel, homes, roads and low-lying areas.

The storm’s projected strength is severe. The IMD says it will likely become a severe cyclonic storm around October 27, then ultimately peak as a very severe cyclonic storm. Near landfall, maximum sustained winds may reach 115–125 kmph, while violent gusts could reach 140 kmph.

The most direct threat is along the Andhra Pradesh and Yanam coasts, where the storm may cross between Bapatla and Visakhapatnam. Coastal Andhra Pradesh and Yanam are forecast to receive heavy to very heavy rain, including isolated extremely heavy rain on October 27 and 28. Rayalaseema is also included in thunderstorm forecasts.

The wider weather footprint includes Kerala, Tamil Nadu, Puducherry, Karaikal and coastal Karnataka. Kerala has district-level red, orange and yellow alerts. Tamil Nadu, Puducherry and Karaikal have red alerts, while coastal Karnataka may receive intense showers. The article does not quantify the storm’s geographic width.

Such winds can create serious coastal hazards. Based on established cyclone impacts, sustained winds of 115–125 kmph may uproot trees, damage roofs, break windows, disrupt electricity and communications, and make travel dangerous. Gusts reaching 140 kmph can worsen sudden structural and infrastructure damage. The article describes these as violent gusts but does not provide a damage assessment.

Extremely heavy rainfall can overwhelm drainage and rivers. It may cause flash flooding, waterlogging, reduced visibility and dangerous road conditions. In hilly or steep areas, saturated ground can also raise the risk of landslides. These are general weather hazards associated with the forecast conditions, not specific damage predictions in the article.

The greatest immediate concern is near the projected landfall corridor between Bapatla and Visakhapatnam. Coastal Andhra Pradesh and Yanam face extremely heavy rain on October 27 and 28. Officials and residents should use IMD updates to guide evacuation, sheltering, travel and emergency preparations.

The IMD monitors a weather system’s position, movement, development and likely track. It also estimates how quickly the system may strengthen and where it could reach the coast. These updates matter because governments, emergency agencies, fishermen, transport services and residents use them to prepare for dangerous weather.

In this case, the IMD reported that the depression was moving southeastwards at 8 kmph as of October 24. It forecast a southward movement on October 25, intensification into a Deep Depression, and a gradual west-northwestward recurve by October 26 morning. It then projected severe and very severe cyclone stages.

The department also communicates timing, wind speeds, landfall location and rainfall alerts. It forecast landfall between Bapatla and Visakhapatnam on October 28, with winds of 115–125 kmph and gusts up to 140 kmph. It issued red, orange and yellow alerts for affected districts and regions.

These are intensity categories based mainly on maximum sustained wind speed. Under the IMD scale, a depression has winds of 31–50 kmph, and a Deep Depression has 51–61 kmph. The categories show that a system is strengthening, although rainfall, track and local impacts also matter.

A severe cyclonic storm has maximum sustained winds of 89–117 kmph. A very severe cyclonic storm has 118–166 kmph. The article’s projected landfall winds of 115–125 kmph overlap the upper severe range and the very severe range, while gusts can be higher than the classification’s sustained wind measure.

The article reports a forecast progression from depression to Deep Depression, then severe cyclonic storm, and finally very severe cyclonic storm. These technical labels help the IMD communicate rising intensity. The article does not state the system’s exact wind speed at each earlier stage, so only the forecast categories and landfall winds are certain here.

A disturbance over warm tropical water can intensify when the ocean supplies heat and moisture to rising air. Condensation releases additional energy, lowering pressure and strengthening circulation. This explanation uses established meteorological knowledge; the article itself only reports the system’s forecast intensification.

Its direction can change because steering winds vary with altitude and location. The Earth’s rotation also influences the system’s circulation and movement. In the article, the depression had moved southeastwards at 8 kmph, was expected to move nearly southwards on October 25, and then gradually recurve west-northwestwards by October 26 morning.

The IMD expects several stages of strengthening: Deep Depression on October 25, severe cyclonic storm around October 27, and very severe cyclonic storm before landfall. The system is forecast to reach the Andhra Pradesh coast on October 28. Exact changes depend on atmospheric and ocean conditions monitored in later updates.
