The much-awaited Southwest Monsoon 2018 has finally arrived over Andaman and Nicobar Islands. The Northern Limit of Monsoon (NLM) is currently passing through South Andaman Sea and Car Nicobar Islands.
The weather conditions remain favourable for the advancement of the NLM over some more parts of Bay of Bengal and Arabian Sea that includes, Lakshadweep, South Kerala coast, Sri Lanka and northern parts of Andaman Sea during the next 24-48 hours. The system is likely to reach Kerala coast before the normal date of Monsoon that is June 1.

Now let us have a look at the weather forecast across the country.
Beginning with the weather over North India – The Western Disturbances had moved away, thus rainfall activity will reduce over Jammu and Kashmir and Himachal Pradesh. A cyclonic circulation is seen over South Punjab and adjoining Pakistan. But we do not expect any weather activity over Northwest India. Thus, heatwave condition may also develop over parts of South Punjab, parts of Haryana and West Uttar Pradesh. Meanwhile, severe heatwave conditions will continue and even expand in some more parts of Rajasthan, Delhi.
Moving to the weather in East and Northeast India – A cyclonic circulation is over East Bihar. A trough is extending across Bihar to Arunachal Pradesh. Therefore, we expect moderate to heavy showers over Sub-Himalayan West Bengal, Sikkim and parts of northeast states. Isolated showers over Gangetic West Bengal, East Bihar, East Jharkhand and Odisha may also occur. Meanwhile, western parts of Bihar, Jharkhand and parts of Odisha are likely to reel under heatwave type conditions. In fact, temperatures would witness a rising trend in parts of West Bengal and Coastal Odisha.
Further in Central India – a cyclonic circulation lies in the lower levels. A trough is extending from South Uttar Pradesh to South Tamil Nadu across Maharashtra and Kerala. Isolated rain and thunderstorm may occur over South Chhattisgarh, Southeast Madhya Pradesh and adjoining Vidarbha, Madhya Maharashtra and Konkan and Goa. Meanwhile, heatwave conditions would continue to grip many parts of Central India.

Lastly in South India – a cyclonic circulation is seen over Southwest Bay of Bengal and adjoining Tamil Nadu coast and a low-pressure area is expected to form over East Central Bay of Bengal. Therefore, moderate to heavy rains will lash parts of Kerala, South Karnataka, West and South Tamil Nadu.
With Monsoon making an onset over Andaman, we expect heavy to very showers over Andaman and Nicobar Islands. Meanwhile, light rain over remaining southern peninsula cannot be ruled out. With increased rains, East and West coast of the country may also experience high waves during next 24 to 48 hours. Thus, people are advised to stay cautious.
