The first day of July, the most crucial month during the annual rainy season, began on a sedate note with a moderate revival in monsoon fortunes.

Helpful cyclonic circulations located strategically to either side of the peninsula drove in rains along the west coast, adjoining peninsula and east India.

OFFSHORE TROUGH

The offshore trough along the west coast, which collects moisture moped up off the Arabian Sea to rain them down, lay extended from Gujarat coast to Kerala coast.

This full-length trough is topped off by a cyclonic circulation over off Maharashtra and Gujarat coasts, which is a good augury. To the other side of the peninsula, twin cyclonic circulations hung down over west-central Bay of Bengal and northwest Bay of Bengal and adjoining coasts.

Meanwhile, India Meteorological Department (IMD) said Sunday’s rain pattern would continue to hold for the next two days. Heavy rains have been forecast over Konkan, Goa, coastal and north interior Karnataka, Telangana, coastal Andhra Pradesh, south Chhattisgarh and Orissa.

HEAVY RAINS

An extended outlook valid until the weekend said thundershowers would lash many places over west coast, east and adjoining central India and the Northeastern States.

Importantly, it also saw an increase in rainfall activity over northwest India.

But global weather agencies suspect that the northwest Pacific could rustle up another storm around this time, which could distract the monsoon flows.

The European Centre for Medium-Range Weather Forecasts sees monsoon flows over Arabian Sea beginning to taper off around this time.

The US National Centres for Environmental Prediction suggests that the monsoon may not run up over the entire land mass by the scheduled July-15 timeline.

TWO-DAY OUTLOOK

Rain has been forecast at many places over west coast, interior Maharashtra, interior Karnataka, Lakshadweep and Andaman and Nicobar Islands for the next two days.

Adjoining east Gujarat and south Madhya Pradesh may also benefit from the wet session.

Towards the east, thundershowers may break out at many places over Orissa, south Chhattisgarh, Andhra Pradesh, West Bengal, Sikkim and the Northeastern States.
