West Bengal and Sikkim remain under alert as some areas are expected to experience extremely heavy rainfall due to active monsoon systems.
Uttarakhand, Assam, Meghalaya and Chhattisgarh have received an Orange Alert with forecasts of heavy to very heavy rainfall and possible disruption.
Delhi-NCR may receive light rains, but high humidity and high temperatures will continue to plague residents across the region.
The monsoon trough and low pressure system over West Bengal is likely to lead to increased rainfall over eastern and central India.
Thunderstorms, lightning and strong winds are expected in several states, with fishermen receiving warnings due to rough sea conditions.
The southwest monsoon remained active across much of India on Saturday, with the India Meteorological Department (IMD) issuing a red alert for sub-Himalayan West Bengal and Sikkim amid forecasts of extremely heavy rainfall. An active monsoon low coupled with a low pressure area over West Bengal is expected to cause widespread rainfall over eastern, central and northern India over the next 24 hours, while Delhi-NCR is likely to continue to experience oppressive heat and humidity despite the possibility of light showers.
Delhi will see cloudy skies but relief will be limited
Delhi and the National Capital Region will experience partly cloudy skies throughout the day with isolated spells of light rain likely in the afternoon or evening, the IMD said. However, these showers are unlikely to provide much respite from the prevailing heat and humidity. The maximum temperature is expected to hover around 36 degrees Celsius while the minimum temperature is expected to remain between 28-30 degrees Celsius. Winds will likely blow at 20-30 km/h. Similar weather conditions are expected in parts of Haryana, Chandigarh and Punjab where wet weather will continue to cause discomfort.
Low pressure area promoting precipitation
Meteorologists said the low pressure area that formed over Ganga, West Bengal and adjoining Jharkhand and north Odisha has moved northwest and is now centered over Ganga, West Bengal. The associated cyclonic circulation extends almost 5.8 km above mean sea level. While the system is expected to weaken gradually over the next 12 hours, it will continue to influence weather conditions over eastern and central India, supporting widespread rainfall activity.
Currently, the monsoon trough extends from Amritsar through Muzaffarnagar, Shahjahanpur, Basti, Patna and the center of the low pressure area and then extends towards the northeastern Bay of Bengal. This alignment created very favorable conditions for prolonged rainfall in several states.
Red and orange warning for heavy rain
The IMD has issued a red alert for the sub-Himalayan regions of West Bengal and Sikkim, warning of heavy to very heavy rainfall, with isolated places likely to receive extremely heavy downpours exceeding 204.5mm. Such intense rainfall increases the risk of flash floods, river overflows and landslides in vulnerable areas.
An orange alert has also been issued for Arunachal Pradesh, Assam, Meghalaya, Chhattisgarh and Uttarakhand where heavy to very heavy rainfall ranging from 115.6 mm to 204.4 mm is expected. Authorities advised residents in these regions to remain vigilant, especially in low-lying and hilly areas prone to flooding and slope failures.
Several states are on yellow alert
Heavy rainfall is also forecast in Bihar, eastern Uttar Pradesh, Jharkhand, Odisha, Himachal Pradesh, eastern Madhya Pradesh, Karnataka, Kerala, Nagaland, Manipur, Mizoram and Tripura, prompting the IMD to issue a yellow alert. Rainfall amounts between 64.5mm and 115.5mm are likely in many areas. Continuous rainfall can lead to waterlogging in urban centers and increase the likelihood of landslides in mountainous areas.
