Western disturbances to quell heat, monsoon stays stuck over Bay

While the monsoon is stuck over the South Andaman Sea and Southeast Bay of Bengal three days after the Indian Meteorological Department (IMD) announced its arrival, an emerging powerful cyclone over the western Pacific may take center stage, intensifying flows and helping its cause. over the bay.

The typhoon is expected to initially race west across the Pacific Ocean towards Taiwan where it may reverse and drive itself away.

While the southern parts of the Gulf may make some gains, the same cannot be said of the Arabian Sea off the coast of Kerala where the monsoons hit land first.

Arabian Sea alienation

IMD short-term projections and global models indicate that an unfriendly zone of high pressure (cyclone) will hold over the Arabian Sea at least until June 1, suppressing cloud formation or precipitation.

But parts of the west coast, the inner peninsula, the Middle East and northwest neighboring India could see showers or thundershowers from the western disturbance across northern India.

Since monsoon flows will be evident due to their absence during this period (till 1st June), these disturbances (low pressure waves) will prompt extension of the fringes in the form of weather-friendly basins southward into central India and the southern peninsula.

Moist air from the Arabian Sea will rush as hot air expands over land, cool, and thunderstorms.

Low temperatures during the day

Accordingly, maximum temperatures (today) may rise by 2-3°C over northwest India until tomorrow (Tuesday) and fall by 3-5°C with rain, thunderstorms, lightning and even hail onset thereafter.

No significant change in the maximum temperature was observed in the rest of the country over the next five days.

Heat wave conditions may appear over parts of southern Haryana, Delhi, southern parts of Uttar Pradesh, western Rajasthan, eastern Madhya Pradesh, plains of West Bengal and Jharkhand today.

Eastward, roughly similar conditions will emerge as westerly disturbances continue their journey eastward over northern and eastern India, lowering ‘payloads’ of erratic weather along demand-generated basins as moist air from the Gulf fills the void left by the ascent. Hot air.

Rain, thunderstorms, lightning and high winds will also result here.

Rain and thunderstorms

Monsoons can only enter these regions after these basins on suitably heated ground have ceased.

Western disturbance activity must also end for the Gulf arm of the monsoon to enter central and northwest India (the monsoon follows a similar approach since then with the Gulf and Arabian Sea arms hitting the east and west coasts respectively to begin).

IMD said this morning (Monday) that the northern boundary of the monsoon continued to pass through Nankuri in South Andaman.

Conditions are favorable for further progress in some other parts of the southern Gulf, Andaman Sea, and the Andaman and Nicobar Islands over the next 2-3 days.

A strong southwesterly wind blows from the Gulf to northeastern India.

New Western Disorder

The prevailing western unrest has reached Northeast India even with the successor likely to affect Northwest India from Tuesday.

This will also be active and will prevail differently until the end of the month (May 30) even when another run over the Mediterranean Sea begins to roll. It can hit northwest India with some intensity if the monsoon isn’t out by then.

IMD’s forecast for the next few days is helpful. Widespread rain, thunderstorms, lightning and gusty winds are likely to be somewhat widespread over the hills of northwest India and isolated from scattered precipitation over the plains from Tuesday to Friday.

Thunderstorms (wind speeds of 50 to 60 kmph), hail and lightning are likely over Uttarakhand while heavy rains may lash parts of Jammu and Kashmir and Himachal Pradesh.

Central and Southern India

Over central India, light to moderate to isolated rain, thunderstorms, lightning and gusty winds are expected in Vidarbha and Chhattisgarh over the next three days and over Madhya Pradesh until Friday.

Over southern India, isolated to scattered light to moderate rain is expected over the next five days over many parts of the region.

Thunderstorms, lightning and gusty winds likely over coasts of Andhra Pradesh, Telangana, Tamil Nadu, Puducherry and Karikal until Friday; over inland Karnataka until Tuesday (tomorrow); and over Kerala and Mahe for the next five days.
