New Delhi, A low pressure area formed over Arabian sea and Lakshadweep is likely to intensify further into a cyclonic storm and reach coastal states of Maharashtra and Gujarat next week, the Indian Meteorological Department (IMD) said on Sunday.

Sunitha Devi, in charge of cyclones at IMD, said, "A low pressure area has formed over southeast and adjoining east central Arabian sea and Lakshadweep area. It is very likely to concentrate into a depression during the next 24 hours and intensify further into a cyclonic storm during subsequent 24 hours."

She added, "It is likely to move nearly northwards and reach near north Maharashtra and Gujarat coasts by 3rd June."

A low pressure area and a depression are the first two levels on the IMD's eight-category scale used to classify cyclones based on their intensity.

The weather bureau said that the sea condition will be very rough and advised fishermen not to venture into the sea till June 4.

It has forecast heavy to very heavy rainfall over south coastal Maharashtra for June 2-4, on north coast on June 2-3 and in Gujarat, Daman and Diu and Dadar and Nagar Haveli on June 3-5.

IMD said that under the influence of likely formation of a low pressure system over Arabian Sea, conditions will become favourable from June 1 for onset of monsoon over Kerala.

The arrival date for monsoon in Kerala is around June 1 every year and in Maharashtra around June 10.

On Saturday, a private forecasting agency claimed that monsoon has already hit Kerala, but the assertions were quickly rebutted by the Ministry of Earth Sciences.

"The news about monsoon onset over Kerala in Social Media is not correct. Monsoon has not arrived over Kerala. The greatest enemy of knowledge is not ignorance, it is the illusion of knowledge a"Stephen Hawking," saidAMadhavan Rajeevan, Secretary, Ministry of Earth Sciences.

Kuldeep Srivastava, the head of IMD's Regional Weather Forecasting Centre said that the formation of a low pressure system in Arabian sea and its movement towards Gujarat coast will bring moisture to Delhi-NCR and North West India from June 3.

Two storms are forming over the Arabian Sea, one lies off the African coast and is likely to move over Oman and Yemen, while the other is placed close to India.

The development comes almost ten days after 'Amphan' pummeled four districts of Bengal in the fiercest cyclone in the region in a century, that left 86 people dead and rendered ten million people homeless.
