Cyclonic circulation to bring heavy rain over parts of West Bengal, Assam during next 48 hours

The weather system which originally formed as a cyclonic circulation in north Bay of Bengal has been lingering on for quite some time. It intensified into a low pressure system and has been vital in giving Monsoon rain to Northeast India, Sub Himalayan West Bengal, Bihar and Uttar Pradesh. It has already weakened and is now positioned over Bihar and adjoining Sub Himalayan West Bengal as an upper air cyclonic circulation.

After bringing good Monsoon rain over many parts of central and east Uttar Pradesh on Monday, rainfall has reduced over the entire state.

In the last 24 hours, this low pressure system brought a whopping 776 mm of rain over Cherrapunji,  Malda received 67 mm, Shillong 51, Bagdogra 38 mm, Cooch Behar 26.4 mm of rain.

As the system is moving away from Uttar Pradesh, rain has reduced in Bahraich and Fursatganj, where 315 mm and 358 mm of rain respectively had been observed on Sunday. Rain has reduced in Bihar as well with Patna receiving only 0.6 mm of rain.  According to the latest weather update by Skymet Meteorology Division in India, the system is moving along the foothills in a west to east direction. It will continue to move slowly and give intense weather activity over Sub Himalayan West Bengal and Northeast India, particularly Arunachal Pradesh and Assam for the next 48 hours.

The system has been bringing good Monsoon rain over East India and played a crucial role in mitigating the rain deficiency in other parts of the country.

Latest update on super typhoon Neoguri

Super Typhoon Neoguri pounded Okinawa Islands of Japan on Tuesday. While passing over the southern Islands, Neoguri had a wind speed of 175 kmph and gusts up to 250 kmph, forcing residents to take refuge from destructive winds, towering waves and strong surges.

About 480,000 residents of Okinawa were urged by the Japanese government to stay at home or take refuge at community centres. Airports were also closed and residents living in the low lying areas along the shorelines were evacuated. More than 50,000 households were reported to be without power.

According to Japanese officials, the Typhoon could be one of the strongest to hit Japan in decades.

Typhoon Neoguri is in the process of recurving and heading northeastward threatening mainland Japan with inclement weather conditions.

Meanwhile, there is another Typhoon Fausto building up in the eastern pacific. It is equivalent to a category one hurricane. It is expected to intensify further but move away from the coastlines.

India is the world's second-biggest Cotton producer country.  Cotton yields have been rising due to the increasing use of hybrid and genetically modified seed. Despite rising production, exports are expected to trend lower in the coming years as local mills raise consumption and China buys less, said the official from Agriculture Ministry.

Weather forecast for the week in India from 7th July to 13th July

According to the latest weather update by Skymet Meteorology Division in India, Monsoon in India may make some progress this week and the western arm of the Monsoon Line may cover some more parts of Gujarat. Here’s a detail look of the weather in India this week:

North India: Weather in North India is expected to be mostly dry this week. Weathermen inform us that chances of rain/thundershowers in the northern plains are very rare. Rain if any could be isolated and purely localized in nature, triggered by high temperatures or excessive humidity. Maximums in North India are expected to settle close to 40⁰C in many parts of Delhi, Haryana and Rajasthan. In the absence of any Monsoon rain, day temperatures could settle 2 to 4 degrees above the normal average in Punjab too. Dry weather will be attributed to a flow of dry and northwesterly winds from Rajasthan. Cloud cover remains scattered/partly cloudy in North India this week too. Humidity could exceed 80% in the morning hours, leading to high minimums (close to 30⁰C).

East and Northeast India: While North will witness a dry week, weather in East and Northeast India will be the exact opposite. In East India, rainy weather is likely to continue, pulling down the mercury to lower thirties. It may come down to settle in the higher twenties in pockets. The low pressure system could bring heavy rain to the foothills of Uttar Pradesh and Bihar in next 48 hours as the system may move from west to east now. The low pressure will turn into a cyclonic circulation thereafter and cover Sub Himalayan West Bengal and Northeast India, giving good amounts of rain in the region.  Meanwhile, the weather in Uttar Pradesh could turn dry mid-week onwards as the system will move away. Districts along the foothills of Uttar Pradesh have already received over 300 mm of rain on Sunday, 6th July

Central India: Some good news is in store for Central India this week. Meteorologists tell us that there is a possibility that the western arm of the NLM (Northern Limit of Monsoon), which has been stagnant for over twenty days now, could advance further into remaining parts of Madhya Pradesh, some parts of Gujarat and Rajasthan. And as the Monsoon line enters these states, it could bring some good rain along with it. This development could occur towards the end of the week or it might also spill over to the first half of the next week. Till then, Gujarat, Rajasthan and west Madhya Pradesh will be the hottest and driest belt of India, with temperatures exceeding 40⁰C. Other than these states, Maharashtra is also in for some good news. Parts of Vidarbha and Marathwada could observe some good showers during the entire week.

South India: Weather in South India will be rainy in many places this week. However, Kerala will remain mostly dry with scanty rain. Monsoon will be active over Andhra Pradesh and good rain is expected over Telangana and Rayalaseema. Moderate to heavy isolated rain is expected during the first half of the week, after which it will become dry. Monsoon rain is also likely over Goa during the first half of the week. Rain may increase along Maharashtra coast (including Mumbai) during the second half of the week. Coastal and interior Karnataka may receive rain both due to the westerly surge from the Arabian Sea, and from the trough running from East India up to north Tamil Nadu, across interior Karnataka.
