Hot and dry weather conditions have been prevailing over northwest and central parts of the country, barring Northeast India and states on the East Coast of India that saw rains courtesy Cyclone Fani. The last when country had witnessed pre-Monsoon rains was from April 15 to 17, which was also the first widespread spell of the pre-Monsoon season.
Since the Cyclone Fani has now finally dissipated, the weather of most parts of the country have become dry once again. This has led to increase in the day temperatures. In fact, heat wave is likely to make a comeback anytime now over entire Northwest and Central India.
However, it seems that country would be fortunate enough to get a breather from heat wave quite soon. According to weathermen, country is now gearing up for another fairly widespread spell of pre-monsoon activities from May 10. The approaching spell would be a prolonged one i.e. activities are expected to continue until May 15. This would be main reason which would bring much needed relief from the ongoing hot weather for the country, particularly heat wave prone areas of Madhya Pradesh, Rajasthan, Maharashtra, Telangana and Rayalaseema.
Multiple Weather Systems:
The reason for the upcoming pre-Monsoon spell can be attributed to the formation of multiple weather systems forming over parts of the country. To begin with north, two successive Western Disturbances on May 10 and May 13 would be seen affecting Western Himalayas, which are likely to induce a cyclonic circulation over Rajasthan and adjoining areas.
A trough will also extend from northern plains to eastern parts of Uttar Pradesh, leading to increased rain activities. Simultaneously, a cyclonic circulation would also be seen over sub-Himalayan West Bengal.
Another deep trough would be forming from Uttar Pradesh to Southeast Arabian Sea, while a Confluence Zone will form over Central India.
As per weathermen, whenever there is such situation wherein in we see multiple weather systems forming simultaneously, they all complement each other and tend to stay for a longer duration. Thus, resulting in prolonged weather activities over wider area. India, in the coming days, would see such kind of spell.
Rainfall Pattern
From April 10, we can expect fairly widespread rain and thundershowers all across Jammu and Kashmir, Himachal Pradesh and Uttarakhand. In plains, dust storm or thundershower activities would begin over Punjab, Haryana, Delhi and parts of Rajasthan on May 10.
By May 11, Madhya Pradesh, Maharashtra, parts of Chhattisgarh, coastal Andhra Pradesh, Interior Tamil Nadu, Kerala and South Interior Karnataka will also start receiving some pre-monsoon activities.
By May 13 and 14, we expect rains to cover parts of Uttar Pradesh, Bihar, Jharkhand and Odisha as well. On and off rains will continue over Northeast India throughout.
So, we can say that almost entire country including isolated pockets of Gujarat is gearing up for a rainy spell very soon.
During this time, northwestern plains might get some intense dust storm and thundershower activities, with wind speed might reaching up to 100 kmph. East India might also witness Nor’westers and intense lightning strikes during this period.
These pre-Monsoon activities would be instrumental in taking country out of the clutches of heat wave, which by then would have gripped entire India tightly.
